AB  - Astrocytes are the main homeostatic cells in the central nervous system, with the unique ability to transform from quiescent into a reactive state in response to pathological conditions by reacquiring some precursor properties. This process is known as reactive astrogliosis, a compensatory response that mediates tissue damage and recovery. Although it is well known that SOX transcription factors drive the expression of phenotype-specific genetic programs during neurodevelopment, their roles in mature astrocytes have not been studied extensively. We focused on the transcription factors SOX2 and SOX9, shown to be re-expressed in reactive astrocytes, in order to study the reactivation-related functional properties of astrocytes mediated by those proteins. We performed an initial screening of SOX2 and SOX9 expression after sensorimotor cortex ablation injury in rats and conducted gain-of-function studies in vitro using astrocytes derived from the human NT2/D1 cell line. Our results revealed the direct involvement of SOX2 in the reacquisition of proliferation in mature NT2/D1-derived astrocytes, while SOX9 overexpression increased migratory potential and glutamate uptake in these cells. Our results imply that modulation of SOX gene expression may change the functional properties of astrocytes, which holds promise for the discovery of potential therapeutic targets in the development of novel strategies for tissue regeneration and recovery.

AB  - Astrocytes are the main homeostatic cells in the brain with important roles both in
physiological and pathological conditions. They have a unique ability to become
reactivated in response to different types of brain pathologies, which serves as a
compensatory response that modulates tissue damage and recovery. Also, senescent
astrocytes have profound implications in age-related neurodegenerative disorders. The
molecular mechanisms underlying astrocyte reactivation and senescence are still not
well understood. To investigate the roles of SOX2 and SOX9 transcription factors and
miR-21 in these phenotypic alternations of astroglia, astrocytes derived from NT2/D1
cell line (NT2/A) were used as a model system. Western blot analyses showed that the
expression of both SOX2 and SOX9 decreases during the maturation of NT2/A and
they are re-expressed upon in vitro induced injury. Further modulation of the SOX2
and SOX9 expression will reveal their roles in the regulation of astrocytes
reactivation. Down-regulation of mir-21 in both immature and mature NT2/A by
using the antisense technology, induced the decline in cell proliferation revealed by
Ki67 proliferation marker. Also the premature cellular senescence was induced as
indicated by increase in SA-ß-gal activity and the expression of p21 and p53.
Additionally, in silico analysis predicted many of the genes, previously shown to be
upregulated in senescent astrocytes, as miR-21 targets.
Clarifying the roles of SOX genes and miRNAs in astrocyte reactivation and
senescence would contribute to better understanding of the functions of these cells at
the molecular level, which holds promise for development of new therapeutic
strategies.

AB  - Introduction: Prolonged exposure to sunlight, has a harmful effect on skin cells encompassing reduced
viability, morphological changes, and altered gene expression. The two most prevalent types ofskin cancer,squamous cell carcinoma (cSCC) and basal cell carcinoma (BCC), arise from malignant transformation
of keratinocytes. UV radiation, among other factors, serves as the primary cause of these tumors. Previous data hasshown that changesin different SOX genes expression in these cancer types correlates with
disease progression, suggesting their role as oncogenes/tumor suppressors. The presented work is focused on examining the impact of UVB radiation on the expression of SOX2 and SOX9 genesin HaCaT cells
derived from human keratinocytes.
Methods: Using a custom-made UV solarsimulator for the irradiation of HaCaT cells with 150 mJ/cm2 or
300 mJ/cm2
, we analyzed SOX2 and SOX9 gene expression. In order to determine the protective effects
of quercetin, anti-inflammatory bioflavonoid, we treated irradiated HaCaT with quercetin, and analyzed
SOX gene expression.
Results: Our resultsindicate that UVB radiation induces a dose dependent decrease of SOX2 expression
while expression of SOX9 was increased at the dose of 150 mJ/cm2 in HaCaT. Treatment of cells with
quercetin increased the expression of both SOX2 and SOX9 genesin HaCaT cellsfollowing UVB radiation
at both doses compared to irradiated cells.
Conclusions: Further research is needed to understand the molecular mechanisms and significance of
SOX2 and SOX9 in UVB-induced cellular responses, in the context of nonmelanoma cancers with potential implications for targeted therapeutic strategies for nonmelanoma cancers

AB  - Brain trauma leads to the induction of neural stem cell proliferation and the migration
of young neurons to injured areas. However, these neurons are insufficient to fully
restore neuronal function due to the limited potential of adult neurogenesis. This study
aimed to investigate the effect of hypoxia, a condition that underlines a wide spectrum
of brain pathologies, on pluripotency and the capacity of stem cells to differentiate
into neural progenitors. We analyzed the expression of SOX genes and microRNAs as
they control a variety of cellular processes during neuronal differentiation, including
cell proliferation and cell fate determination. In vitro neuronal differentiation of
human embryonal carcinoma cell line NT2/D1 and induced pluripotent stem cells
were used as a model system of adult neurogenesis. Cobalt chloride was used to
induce hypoxia.
The results of the analysis showed that, following hypoxia, the efficiency of neuronal
induction was significantly decreased, that coincident with decline in mRNA
expression levels of SOXB and SOXC genes. In contrast to that, the expression level of
miR-21 was significantly increased.
Our findings advance the study of SOX TFs, miR-21, and their possible interplay in
ischemia-related pathologies, establishing them as prospective biomarkers and
possible targets for future diagnostic and therapeutic approaches.

AB  - The quest for eternal youth and immortality is as old as humankind. Ageing is an inevitable physiological process accompanied by many functional declines that are driving factors for age-related diseases. Stem cell exhaustion is one of the major hallmarks of ageing. The SOX transcription factors play well-known roles in self-renewal and differentiation of both embryonic and adult stem cells. As a consequence of ageing, the repertoire of adult stem cells present in various organs steadily declines, and their dysfunction/death could lead to reduced regenerative potential and development of age-related diseases. Thus, restoring the function of aged stem cells, inducing their regenerative potential, and slowing down the ageing process are critical for improving the health span and, consequently, the lifespan of humans. Reprograming factors, including SOX family members, emerge as crucial players in rejuvenation. This review focuses on the roles of SOX transcription factors in stem cell exhaustion and age-related diseases, including neurodegenerative diseases, visual deterioration, chronic obstructive pulmonary disease, osteoporosis, and age-related cancers. A better understanding of the molecular mechanisms of ageing and the roles of SOX transcription factors in this process could open new avenues for developing novel strategies that will delay ageing and prevent age-related diseases.

AB  - Arranged patterns obtained via ultrafast laser processing on the surface of Ti/Cu/Ti/Si and Ti/Zr/Ti/Si thin-film systems are reported. Two differently designed multilayer thin films Ti/Cu/Ti/Si and Ti/Zr/Ti/Si were deposited on silicon using the ion sputtering method. The bioactive surfaces of these systems involve the formation of laser-induced periodic surface structures (LIPSS) in each of the laser-written lines of mesh patterns on 5 × 5 mm areas. The formation of nano- and micro-patterns with an ultra-thin oxide film on the surfaces was used to observe the effects of morphology and proliferation of the MRC-5 cell culture line. To determine whether Ti-based thin films have a toxic effect on living cells, an MTT assay was performed. The relative cytotoxic effect, as a percentage of surviving cells, showed that there was no difference in cell number between the Ti-based thin films and the control cells. There was also no difference in the viability of the MRC-5 cells, except for the Ti/Cu/Ti/Si system, where there was a slight 10% decrease in cell viability.

The bioactive surfaces of these systems involve the formation of laser-induced periodic surface structures (LIPSS) in each of the laser-written lines of mesh patterns on 5 × 5 mm areas. The formation of nano- and micro-patterns with an ultra-thin oxide film on the surfaces was used to observe the effects of morphology and proliferation of the MRC-5 cell culture line. To determine whether Ti-based thin films have a toxic effect on living cells, an MTT assay was performed. The relative cytotoxic effect, as a percentage of surviving cells, showed that there was no difference in cell number between the Ti-based thin films and the control cells. There was also no difference in the viability of the MRC-5 cells, except for the Ti/Cu/Ti/Si system, where there was a slight 10% decrease in cell viability.",

AB  - Astrocytes are the main homeostatic cells in the central nervous system (CNS) that provide mechanical,
metabolic, and trophic support to neurons. Disruption of their physiological role or acquisition of
senescence-associated phenotype can contribute to the CNS dysfunction and pathology. However, molecular
mechanisms underlying the complex physiology of astrocytes are explored insufficiently. Recent studies have
shown that miRNAs are involved in the regulation of astrocyte function through different mechanisms.
Although miR-21 has been reported as an astrocytic miRNA with an important role in astrogliosis, no link
between this miRNA and cellular senescence of astrocytes has been identified. To address the role of miR-21
in astrocytes, with special focus on cellular senescence, we used NT2/A (astrocytes derived from NT2/D1
cells). Downregulation of miR-21 expression in both immature and mature NT2/A by the antisense
technology induced the arrest of cell growth and premature cellular senescence, as indicated by senescence
hallmarks such as increased expression of cell cycle inhibitors p21 and p53 and augmented senescenceassociated
β-galactosidase activity. Additionally, in silico analysis predicted many of the genes, previously
shown to be upregulated in astrocytes with the irradiation-induced senescence, as miR-21 targets. Taken
together, our results point to miR-21 as a potential regulator of astrocyte senescence. To the best of our
knowledge, these are the first data showing the link between miR-21 and cellular senescence of astrocytes.
Since senescent astrocytes are associated with different CNS pathologies, development of novel therapeutic
strategies based on miRNA manipulation could prevent senescence and may improve the physiological
outcome.

AB  - Astrocytes, as the most abundant glial cells in the central nervous system, are tightly integrated into neural networks and participate in numerous aspects of brain physiology and pathology. They are the main homeostatic cells in the central nervous system, and the loss of astrocyte physiological functions and/or gain of pro-inflammatory functions, due to their reactivation or cellular senescence, can have profound impacts on the surrounding microenvironment with pathological outcomes. Although the importance of astrocytes is generally recognized, and both senescence and reactive astrogliosis have been extensively reviewed independently, there are only a few comparative overviews of these complex processes. In this review, we summarize the latest data regarding astrocyte reactivation and senescence, and outline similarities and differences between these phenotypes from morphological, functional, and molecular points of view. A special focus has been given to neurodegenerative diseases, where these phenotypic alternations of astrocytes are significantly implicated. We also summarize current perspectives regarding new advances in model systems based on astrocytes as well as data pointing to these glial cells as potential therapeutic targets.

AB  - Precise tuning of gene expression, accomplished by regulatory networks of transcription factors, epigenetic modifiers, and microRNAs, is crucial for the proper neural development and function of the brain cells. The SOX transcription factors are involved in regulating diverse cellular processes during embryonic and adult neurogenesis, such as maintaining the cell stemness, cell proliferation, cell fate decisions, and terminal differentiation into neurons and glial cells. MicroRNAs represent a class of small non-coding RNAs that play important roles in the regulation of gene expression. Together with other gene regulatory factors, microRNAs regulate different processes during neurogenesis and orchestrate the spatial and temporal expression important for neurodevelopment. The emerging data point to a complex regulatory network between SOX transcription factors and microRNAs that govern distinct cellular activities in the developing and adult brain. Deregulated SOX/microRNA interplay in signaling pathways that influence the homeostasis and plasticity in the brain has been revealed in various brain pathologies, including neurodegenerative disorders, traumatic brain injury, and cancer. Therapeutic strategies that target SOX/microRNA interplay have emerged in recent years as a promising tool to target neural tissue regeneration and enhance neurorestoration. Numerous studies have confirmed complex interactions between microRNAs and SOX-specific mRNAs regulating key features of glioblastoma. Keeping in mind the crucial roles of SOX genes and microRNAs in neural development, we focus this review on SOX/microRNAs interplay in the brain during development and adulthood in physiological and pathological conditions. Special focus was made on their interplay in brain pathologies to summarize current knowledge and highlight potential future development of molecular therapies.

AB  - The family of SOX genes encodes proteins that display properties of both classical transcription factors and architectural components of chromatin. During development of nervous system, as well as adult neurogenesis, SOX transcription factors govern diverse cellular processes such as maintaining the multipotency of neural stem cells, cell proliferation, cell fate decision, migration as well as terminal differentiation of neurons. Despite their well-known function in development and brain homeostasis, the expression and role of these genes in pathology- induced neural stem cell plasticity is poorly understood. Reduction in oxygen supply or ischemia are involved in various pathological conditions, such as stroke, traumatic brain injury and cardiac arrest, which promotes neurogenesis, angiogenesis, cell proliferation and other cell mechanisms for survival under the stress. The aim of the present study was to analyze the expression of SOX genes during in vitro neurogenesis following chemical hypoxia. Neuronal differentiation of human pluripotent embryonal carcinoma stem cell line NT2/D1 was used as an in vitro model system for studying the process of human neurogenesis. Depending on different concentration, RA directed the differentiation of NT2/D1 cells into neurons with a different phenotype. The effect of stress caused by hypoxia on the properties of pluripotent cells as well as the induction of neural differentiation was monitored in vitro by culturing NT2/D1 cells in the presence of cobalt chloride, a chemical inducer of hypoxia. The results of the analysis showed that the effect of hypoxia on the expression of SOX2 and OCT4 proteins involved in maintaining the pluripotency of cells depends on the duration of action of cobalt chloride. After short-term exposure of the cells, an increase in the levels of expression of SOX2 and OCT4 proteins was detected, while long-term treatment of the cells led to a decrease in the expression of these proteins. Furthermore, results showed that depending of duration of cobalt chloride treatments, the level of expression of miR-21 in undifferentiated NT2/D1 cells significantly changed. In addition, long-term pretreatment of pluripotent cells with cobalt chloride resulted in increased expression levels of SOX2, SOX3 and GAD67 proteins in neural progenitors induced for 7 days in the presence of, either low or high concentration of retinoic acid, indicating that hypoxia causes increased efficiency of NT2/D1 cell neural differentiation. Damage of brain tissue caused by reduction of oxygen and/or blood flow to the tissue is the leading cause of death worldwide and the leading cause of disability in humans. Our results contributes to the research focused on discovering the roles of SOX TFs and their gene targets in ischemia related pathologies, making them promising biomarkers and potential targets for future diagnostic and therapeutic strategies.

AB  - The SOX proteins belong to the superfamily of transcription factors (TFs) that display properties of both classical TFs and architectural components of chromatin. Since the cloning of the Sox/SOX genes, remarkable progress has been made in illuminating their roles as key players in the regulation of multiple developmental and physiological processes. SOX TFs govern diverse cellular processes during development, such as maintaining the pluripotency of stem cells, cell proliferation, cell fate decisions/germ layer formation as well as terminal cell differentiation into tissues and organs. However, their roles are not limited to development since SOX proteins influence survival, regeneration, cell death and control homeostasis in adult tissues. This review summarized current knowledge of the roles of SOX proteins in control of central nervous system development. Some SOX TFs suspend neural progenitors in proliferative, stem-like state and prevent their differentiation. SOX proteins function as pioneer factors that occupy silenced target genes and keep them in a poised state for activation at subsequent stages of differentiation. At appropriate stage of development, SOX members that maintain stemness are down-regulated in cells that are competent to differentiate, while other SOX members take over their functions and govern the process of differentiation. Distinct SOX members determine down-stream processes of neuronal and glial differentiation. Thus, sequentially acting SOX TFs orchestrate neural lineage development defining neuronal and glial phenotypes. In line with their crucial roles in the nervous system development, deregulation of specific SOX proteins activities is associated with neurodevelopmental disorders (NDDs). The overview of the current knowledge about the link between SOX gene variants and NDDs is presented. We outline the roles of SOX TFs in adult neurogenesis and brain homeostasis and discuss whether impaired adult neurogenesis, detected in neurodegenerative diseases, could be associated with deregulation of SOX proteins activities. We present the current data regarding the interaction between SOX proteins and signaling pathways and microRNAs that play roles in nervous system development. Finally, future research directions that will improve the knowledge about distinct and various roles of SOX TFs in health and diseases are presented and discussed.

We outline the roles of SOX TFs in adult neurogenesis and brain homeostasis and discuss whether impaired adult neurogenesis, detected in neurodegenerative diseases, could be associated with deregulation of SOX proteins activities. We present the current data regarding the interaction between SOX proteins and signaling pathways and microRNAs that play roles in nervous system development. Finally, future research directions that will improve the knowledge about distinct and various roles of SOX TFs in health and diseases are presented and discussed.",

AB  - Astrocytes are the main homeostatic cells in the central nervous system (CNS) that provide mechanical, metabolic, and trophic support to neurons. Disruption of their physiological role or acquisition of senescence-associated phenotype can contribute to the CNS dysfunction and pathology. However, molecular mechanisms underlying the complex physiology of astrocytes are explored insufficiently. Recent studies have shown that miRNAs are involved in the regulation of astrocyte function through different mechanisms. Although miR-21 has been reported as an astrocytic miRNA with an important role in astrogliosis, no link between this miRNA and cellular senescence of astrocytes has been identified. To address the role of miR-21 in astrocytes, with special focus on cellular senescence, we used NT2/A (astrocytes derived from NT2/D1 cells). Downregulation of miR-21 expression in both immature and mature NT2/A by the antisense technology induced the arrest of cell growth and premature cellular senescence, as indicated by senescence hallmarks such as increased expression of cell cycle inhibitors p21 and p53 and augmented senescence-associated beta-galactosidase activity. Additionally, in silico analysis predicted many of the genes, previously shown to be upregulated in astrocytes with the irradiation-induced senescence, as miR-21 targets. Taken together, our results point to miR-21 as a potential regulator of astrocyte senescence. To the best of our knowledge, these are the first data showing the link between miR-21 and cellular senescence of astrocytes. Since senescent astrocytes are associated with different CNS pathologies, development of novel therapeutic strategies based on miRNA manipulation could prevent senescence and may improve the physiological outcome.

AB  - The newly synthesized coumarin derivative with dopamine, 3-(1-((3,4-dihydroxyphenethyDamino)ethylidene)-chroman-2,4-dione, was completely structurally characterized by X-ray crystallography. It was shown that several types of hydrogen bonds are present, which additionally stabilize the structure. The compound was tested in vitro against different cell lines, healthy human keratinocyte HaCaT, cervical squamous cell carcinoma SiHa, breast carcinoma MCF7, and hepatocellular carcinoma HepG2. Compared to control, the new derivate showed a stronger effect on both healthy and carcinoma cell lines, with the most prominent effect on the breast carcinoma MCF7 cell line. The molecular docking study, obtained for ten different conformations of the new compound, showed its inhibitory nature against CDKS protein. Lower inhibition constant, relative to one of 4-OH-coumarine, proved stronger and more numerous interactions with CDKS protein. These interactions were carefully examined for both parent molecule and derivative and explained from a structural point of view.

AB  - Purpose: Widespread medical use of radiation in diagnosis, imaging and treatment of different central nervous system malignancies lead to various consequences. Aim of this study was to further elucidate mechanism of cell response to radiation and possible consequence on neural differentiation. Materials and methods: NT2/D1 cells that resemble neural progenitors were used as a model system. Undifferentiated NT2/D1 cells and NT2/D1 cells in the early phase of neural differentiation were irradiated with low (0.2 Gy) and moderate (2 Gy) doses of gamma radiation. The effect was analyzed on apoptosis, cell cycle, senescence, spheroid formation and the expression of genes and miRNAs involved in the regulation of pluripotency or neural differentiation. Results: Two grays of irradiation induced apoptosis, senescence and cell cycle arrest of NT2/D1 cells, accompanied with altered expression of several genes (SOX2, OCT4, SOX3, PAX6) and miRNAs (miR-219, miR-21, miR124-a). Presented results show that 2 Gy of radiation significantly affected early phase of neural differentiation in vitro. Conclusions: These results suggest that 2 Gy of radiation significantly affected early phase of neural differentiation and affect the population of neural progenitors. These findings might help in better understanding of side effects of radiotherapy in treatments of central nervous system malignancies.

AB  - Pyrimethanil, a synthetic fungicide widely used for the treatment of pre- and postharvest fungal diseases on different agricultural crops, was explored for its antifungal activity on different fungal strains. The effect of pyrimethanil on fungal ergosterol was tested by using Aspergillus niger as a model organism. Furthermore, it was investigated, if pyrimethanil can effectively reduce the appearance of Aspergillus rot in wounded cherry tomato fruits. The fungicide cytotoxic effect on different human cell lines was evaluated. In addition, its influence on cell proliferation was studied. A. niger was the most resistant fungal strain (MFC 1.88 mu g mu L-1) to the effect of pyrimethanil. Addition of ergosterol doubled the MFC on A. niger, indicating that the compound might interfere with ergosterol, main sterol of fungal cell membrane. Disease incidence of A. niger in wounded cherry tomato fruits was not detected with pyrimethanil treatment of 0.75 mg/wound. Some cytotoxic effects of pyrimethanil on human cell lines were recorded already at 50 ng mu L-1, while the expression of Ki67 marker of proliferation was decreased with 150 ng mu L-1. These results altogether indicate that pyrimethanil is effective in reducing various fungal pathogens, but further use of this fungicide should be reevaluated because of its cytotoxicity.

AB  - Visok stepen očuvanosti tokom evolucije i činjenica da do danas nije opisan nijedan klinički sindrom povezan sa mutacijama u genu SOX14, ukazuju na značajnu ulogu ovog gena tokom embrionalnog razvića. Iako je prošlo dvadeset godina od otkrića gena SOX14, funkcija ovog gena još uvek nije dovoljno istražena. U ovoj doktorskoj disertaciji analizirana je ekspresija i uloga gena SOX14 u procesu neuralne diferencijacije in vitro i regulaciji malignog fenotipa ćelija poreklom od karcinoma grlića materice. Tokom neuralnog razvića kod miša i pileta, gen Sox14 je eksprimiran u određenom setu neuralnih progenitorskih ćelija i u određenim tipovima zrelih neurona u mozgu. Za članove SOXB1 podgrupe, kojoj pripadaju geni SOX1, SOX2 i SOX3, poznato je da doprinose održavanju neuralnih progenitorskih ćelija u stanju proliferacije, sprečavajući proces neuralne diferencijacije, dok se za članove SOXB2 podgrupe, koja obuhvata gene SOX14 i SOX21, pretpostavlja da imaju ulogu u određivanju sudbine neuralnih progenitora, indukujući proces neurogeneze. Smatra se da nivo ekspresije SOX14 i SOX21 proteina tokom neuralnog razvića određuje da li će ćelija ostati neuralni progenitor ili će započeti proces neurogeneze. Iako je okarakterisan kao marker neurona, u ovoj tezi je pokazano da se gen SOX14 eksprimira u pluripotentnim ćelijama, neuronima, kao i u drugim tipovima ćelija koje se dobijaju nakon neuralne diferencijacije pluripotentnih NT2/D1 i P19 ćelija in vitro. Takođe, u ovoj tezi je pokazano da je profil ekspresije SOX14 proteina tokom neuralne diferencijacije sličan profilu ekspresije markera postmitotičkih neurona β-III-Tubulina kod NT2/D1 i P19 ćelija. Rezultati prikazani u ovoj doktorskoj disertaciji su pokazali da izlaskom ćelija iz stanja pluripotentnosti i ulaskom u proces neuralne diferencijacije dolazi do povećanja nivoa ekspresije SOX14 proteina. Pokazano je da SOX14 protein ima preklapajući profil ekspresije sa SOXB1 proteinima tokom procesa neuralne diferencijacije in vitro, a dobijeni rezultati su ukazali na specifičnu regulaciju ekspresije gena SOX14 na post-transkripcionom nivou u pluripotentnim ćelijama.

Dok studije metilacionog statusa na uzorcima tkiva pacijentkinja obolelih od ovog karcinoma ukazuju na odsustvo ekspresije gena SOX14 i njegovu potencijalnu ulogu tumor supresora, in vitro studije na ćelijama poreklom od karcinoma grlića materice ukazuju na onkogeni potencijal ovog gena.

AB  - SOX14 might have an essential role during development due to the high evolutionary conservation and lack of any known mutated phenotype associated with this gene. Although the first SOX14 gene in vertebrates was cloned and characterized two decades ago, the function of this gene is largely unknown. This doctoral dissertation provides an insight into SOX14 expression and its roles during neural differentiation in vitro and in regulation of malignant phenotype of cervical carcinoma cells. During the neural development, the expression of Sox14 gene is restricted to a defined set of neural progenitors and the precise subset of neurons in the brain. Because of its specific expression in the brain, SOX14 is recognised as a marker of neurons. While SOXB1 subgroup of genes, including SOX1, SOX2 and SOX3 genes, maintains neural progenitors' identity, it is proposed that SOXB2 subgroup, comprising SOX14 and SOX21 genes, are important for induction of neurogenesis. It is suggested that the fine balance between expressions of these proteins during early stages of neural development determines neural progenitor identity. Results presented in this thesis show that SOX14 is expressed in pluripotent cells, as well as in neurons and non-neuronal differentiated cells. Also, it is shown that the expression profile of SOX14 correlates to the expression profile of neuronal marker β-III-Tubulin and that the exit of cells from the pluripotent state toward neural differentiation is accompanied with the increased expression of SOX14. It is also shown that the expression of SOX14 overlaps with the expression of SOXB1 proteins during neural differentiation in vitro. The presented results also imply the specific post-transcriptional mechanism of regulation of SOX14 expression in pluripotent cells. Recently it became evident that SOX14 has a role during malignant transformation of the cells. Previous studies showed that SOX14 is methylated in tissues originating from several tumors, including cervical carcinoma. Results obtained by the analysis of the methylation status of SOX14 gene in tissues from cervical carcinoma suggested its potential role as a tumor suppressor, while, on the other hand, in vitro studies suggested that SOX14 exerts oncogenic potential in cervical carcinoma cells. These contradictory data opened up the possibility for further study of the role of SOX14 gene in cervical carcinoma. Results presented in this thesis show that SOX14 exerts tumor suppressor activity in HeLa cells through activation of p53 signaling pathway, one of the most important signaling pathways in cell. In particular, increased expression of SOX14 leads to stabilization of p53 protein by increasing the level of phosphorylated form of p53 protein in HeLa cells. Phosphorylated p53 acts as a transcriptional regulator of target genes that have an important role in tumor growth prevention. The increased expression level of SOX14 and stabilization of p53 are followed by induction of the expression of p53 target genes, mainly involved in apoptosis and cell cycle regulation, such as pro-apoptotic BAX gene and cyclin-dependent kinase inhibitor CDKN1A/p21Waf1/Cip1. Increased expression of SOX14, through activation of a p53 signaling pathway, leads to decreased proliferation, cell cycle arrest and induction of apoptosis...

AB  - Bioactive potential of apigenin derivative apigenin-7-O-glucoside related to its antifungal activity on Candida spp. and cytotoxic effect on colon cancer cells was studied and compared with bioactive potential of apigenin. Antifungal activity was tested on 14 different isolates of Candida spp. using membrane permeability assay, measuring inhibition of reactive oxidative species and inhibition of CYP51 C. albicans enzyme. Cytotoxic potential of apigenin- 7-O-glucoside was tested on colon cancer HCT116 cells by measuring cell viability, apoptosis rate and apoptosis- and colon cancer-related gene expression. Obtained results indicated considerable antifungal activity of apigenin-7-O-glucoside towards all Candida isolates. Breakdown of C. albicans plasma membrane was achieved upon treatment with apigenin-7-O-glucoside for shorter period of time then with apigenin. Reduction of intra-and extracellular reactive oxidative species was achieved with minimum inhibitory concentrations of both compounds, suggesting that reactive oxidative species inhibition could be a mechanism of antifungal action. None of the compounds exhibited binding affinity to C. albicans CYP51 protein. Besides, apigenin-7-O-glucoside was more effective compared to apigenin in reduction of cell's viability and induction of cell death of HCT116 cells. Treatment with both compounds resulted in chromatin condensation, apoptotic bodies formation and apoptotic genes expression in HCT116 cells, but the apigenin-7-O-glucoside required a lower concentration to achieve the same effect. Compounds apigenin-7-O-glucoside and apigenin displayed prominent antifungal potential and cytotoxic effect on HCT116 cells. However, our results showed that apigenin-7-O-glucoside has more potent activity compared to apigenin in all assays that we used.

AB  - SOX14 is a member of the SOX family of transcription factors mainly involved in the regulation of neural development. Recently, it became evident that SOX14 is one of four hyper-methylated genes in cervical carcinoma, considered as a tumor suppressor candidate in this type of malignancy. In this paper we elucidated the role of SOX14 in the regulation of malignant properties of cervical carcinoma cells in vitro. Functional analysis performed in HeLa cells revealed that SOX14 overexpression decreased viability and promoted apoptosis through altering the expression of apoptosis related genes. Our results demonstrated that overexpression of SOX14 initiated accumulation of p53, demonstrating potential cross-talk between SOX14 and the p53 signaling pathway. Further analysis unambiguously showed that SOX14 triggered posttranslational modification of p53 protein, as detected by the significantly increased level of phospho-p53 (Ser-15) in SOX14-overexpressing HeLa cells. Moreover, the obtained results revealed that SOX14 activated p53 protein, which was confirmed by elevated p21 Waf1/Cip1, a well known target gene of p53. This study advances our understanding about the role of SOX14 and might explain the molecular mechanism by which this transcription factor could exert tumor suppressor properties in cervical carcinoma.

AB  - During early vertebrate embryogenesis, the expression of SOXB1 proteins is precisely regulated by a number of different mechanisms, including Wnt/beta-catenin signaling. This is essential for controlling the balance between stemness and differentiation in embryonic stem cells. In the present study, we analyzed the molecular mechanism of LiCl action in NT2/D1 cells and examined the crosstalk between SOXB1 proteins and Wnt signaling in this model system. We have shown that LiCl increases beta-catenin level, induces its translocation to the nucleus and consequently up-regulates beta-catenin/Tcf-dependent transcription in NT2/D1 cells. Our results also suggest that LiCl treatment leads to increased expression of SOX2 and SOX3 proteins in NT2/D1 cells through activation of canonical Wnt signaling. Finally, we have detected a negative feedback loop between beta-catenin and SOX2 expression in NT2/D1 cells. Since beta-catenin and SOX2 have been linked to processes of self-renewal and pluripotency, our results have implications for future research on the maintenance of stemness and lineage commitment of embryonic stem cells.

AB  - SOX14 is a member of the SOXB2 subgroup of transcription factors implicated in neural development. Although the first SOX14 gene in vertebrates was cloned and characterized more than a decade ago and its expression profile during development was revealed in various animal model systems, the role of this gene during neural development is largely unknown. In the present study we analyzed the expression of SOX14 in human NT2/D1 and mouse P19 pluripotent embryonal carcinoma cells. We demonstrated that it is expressed in both cell lines and upregulated during retinoic acid induced neural differentiation. We showed that SOX14 was expressed in both neuronal and non-neuronal differentiated derivatives, as revealed by immunocytochemistry. Since it was previously proposed that increased SOXB2 proteins level interfere with the activity of SOXB1 counteracting partners, we compared expression patterns of SOXB members during retinoic acid induction of embryonal carcinoma cells. We revealed that upregulation of SOX14 expression is accompanied by alterations in the expression patterns of SOXB1 members. In order to analyze the potential cross-talk between them, we generated SOX14 expression construct. The ectopic expression of SOX14 was demonstrated at the mRNA level in NT2/D1, P19 and HeLa cells, while an increased level of SOX14 protein was detected in HeLa cells only. By transient transfection experiments in HeLa cells we showed for the first time that ectopic expression of SOX14 repressed SOX1 expression, whereas no significant effect on SOX2, SOX3 and SOX21 was observed. Data presented here provide an insight into SOX14 expression during in vitro neural differentiation of embryonal carcinoma cells and demonstrate the effect of its ectopic expression on protein levels of SOXB members in HeLa cells. Obtained results contribute to better understanding the role of one of the most conserved SOX proteins.

AB  - OBJECTIVES: Right-left asymmetry of human brain function has been known for a century. Brain asymmetry and lateralization has been observed at the neurochemical level. At the neurochemical level, it is important to further correlate changes in monoaminergic activity with the synthesis and reuptake of these monoamines. The aim of the present study was to analyze the effect of social isolation on catecholamine stores as well as on the regulation of catecholamine synthesis and uptake in the right and left hippocampus. METHODS: We examined changes in protein levels of dopamine-beta-hydroxylase (DBH), norepinephrine transporter (NET) and vesicular monoamine transporter 2 (VMAT2) in the right and left hippocampus of socially isolated adult male rats during 12 weeks by Western blot analysis. RESULTS: Chronic isolation stress reduced norepinephrine content in the right hippocampus. No changes were observed in protein levels of DBH and NET in the right hippocampus, whereas expression of this norepinephrine synthetizing enzyme and transporter were elevated in the left hippocampus. On the other hand, chronic isolation stress caused reduction of VMAT2 protein in the right hippocampus. CONCLUSION: Our results reveale not only the lateralization of stress regulatory system but they also show that long-term isolation stress produces right-left asymmetry of the hippocampus norepinephrine, different regulation of the catecholamines synthesis and reuptake.
