AB  - Introduction: The NT2/D1 embryonal carcinoma cell line represents a well-established in vitro model of
human neurogenesis. It’s widely used for studying neurodevelopmental processes, neurotoxicity, and
neurodegenerative disorders. The utilization of alginate fibers as a 3D cell culture system offers a biocompatible and structurally supportive environment for neural differentiation and maturation of cells,
making it a suitable tool for investigating neurodevelopmental processes.
Methods: In thisstudy, we evaluated the alginate microfibers as a 3D modelsystem for in vitro neural differentiation of NT2/D1 cells.We described the immobilization of NT2/D1 cellsin alginate microfibers and
the effect of propagation in this 3D model on morphological features, viability, and proliferation of immobilized cells. We also assessed the RA-induced initiation of neural differentiation of NT2/D1 cellsin alginate microfibers by comparison with the initiation of neural differentiation in adherent 2D cell culture.
Results: Our results showed that immobilized NT2/D1 acquired morphological features characteristic
of cells propagated in 3D model systems and retain viability, proliferative capacity, and ability to attach
to adherent surfaces. In addition, immobilized NT2/D1 cells preserved neural differentiation capacity.
Upon RA induction we detected a marked decrease in the expression of specific pluripotency-maintaining markers, SOX2, OCT4, and NANOG. Consecutively, the expression of early neural markers, SOX3,
PAX6, and miR219 was significantly increased.
Conclusion: Neural differentiation of NT2/D1 cellsimmobilized within alginate fibersrepresents a highly
promising 3D modelsystem forstudying human neurogenesis and offers a valuable platform forscreening the effect of drugs and bioactive compounds on human neural differentiation.

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  - Nowadays, it is a great challenge to develop new medicines for treating various infectious diseases. The treatment of these diseases is of utmost interest to further prevent the development of multi-drug resistance in different pathogens. Carbon quantum dots, as a new member of the carbon nanomaterials family, can potentially be used as a highly promising visible-light-triggered antibacterial agent. In this work, the results of antibacterial and cytotoxic activities of gamma-ray-irradiated carbon quantum dots are presented. Carbon quantum dots (CQDs) were synthesized from citric acid by a pyrolysis procedure and irradiated by gamma rays at different doses (25, 50, 100 and 200 kGy). Structure, chemical composition and optical properties were investigated by atomic force microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, UV-Vis spectrometry and photoluminescence. Structural analysis showed that CQDs have a spherical-like shape and dose-dependent average diameters and heights. Antibacterial tests showed that all irradiated dots had antibacterial activity but CQDs irradiated with dose of 100 kGy had antibacterial activity against all seven pathogen-reference bacterial strains. Gamma-ray-modified CQDs did not show any cytotoxicity toward human fetal-originated MRC-5 cells. Moreover, fluorescence microscopy showed excellent cellular uptake of CQDs irradiated with doses of 25 and 200 kGy into MRC-5 cells.

AB  - Glioblastoma (GBM) continues to be the most devastating primary brain malignancy. Despite significant advancements in understanding basic GBM biology and enormous efforts in developing new therapeutic approaches, the prognosis for most GBM patients remains poor with a median survival time of 15 months. Recently, the interplay between the SOX (SRY-related HMG-box) genes and lncRNAs (long non-coding RNAs) has become the focus of GBM research. Both classes of molecules have an aberrant expression in GBM and play essential roles in tumor initiation, progression, therapy resistance, and recurrence. In GBM, SOX and lncRNAs crosstalk through numerous functional axes, some of which are part of the complex transcriptional and epigenetic regulatory mechanisms. This review provides a systematic summary of current literature data on the complex interplay between SOX genes and lncRNAs and represents an effort to underscore the effects of SOX/lncRNA crosstalk on the malignant properties of GBM cells. Furthermore, we highlight the significance of this crosstalk in searching for new biomarkers and therapeutic approaches in GBM treatment.

AB  - Carbon quantum dots as a novel type of carbon nanomaterials have attracted the attention of many researchers because of their
unique optical, antibacterial, and anticancer properties as well as their biocompatibility. In this study, for the first time, carbon
quantum dots were prepared from o-phenylenediamine dissolved in toluene by a solvothermal route. Subsequently, the prepared
carbon quantum dots were encapsulated into polyurethane films by a swelling–encapsulation–shrink method. Analyses of the
results obtained by different characterization methods (AFM, TEM, EDS, FTIR, photoluminescence, and EPR) indicate the significant influence of the precursor on structural, chemical, and optical properties. Antibacterial and cytotoxicity tests showed that these
dots did not have any antibacterial potential, because of the low extent of reactive oxygen species production, and showed low dark
cytotoxicity. By investigating the cellular uptake, it was established that these dots penetrated the HeLa cells and could be used as
probes for bioimaging.

AB  - Development of new types of antimicrobial coatings is of utmost importance due to increasing problems with pathogen transmission from various infectious surfaces to human beings. In this study, new types of highly potent antimicrobial polyurethane composite films encapsulated by hydrophobic riboflavin-based carbon polymer dots are presented. Detailed structural, optical, antimicrobial, and cytotoxic investigations of these composites were conducted. Low-power blue light triggered the composites to eradicate Escherichia coli in 30 min, whereas the same effect toward Staphylococcus aureus was reached after 60 min. These composites also show low toxicity against MRC-5 cells. In this way, RF-CPD composites can be used for sterilization of highly touched objects in the healthcare industry.

AB  - Large amounts of hazardous and toxic substances in the environment require non-toxic, cheap, easy, rapid, and sensitive methods for their detection. Blue luminescent graphene quantum dots (GQDs) were produced by electrochemical cleavage of graphite electrodes followed by gamma irradiation in the presence of ethylenediamine (EDA). Modified dots were able to detect metal ions (Co2+, Pd2+, Fe3+) due to photoluminescence quenching. The highest sensitivity was detected for the sample irradiated at a dose of 25 kGy. The limits of detection (LODs) were 1.79, 2.55, and 0.66 μmol L−1 for Co2+, Fe3+, and Pd2+, respectively. It was observed that GQDs irradiated at 200 kGy act as an ultra-sensitive turn-on probe for Malathion detection with LOD of 94 nmol L−1. Atomic force microscopy images proved the aggregation of GQDs in the presence of the investigated metal ions. Results obtained by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and LIVE/DEAD cytotoxicity test indicated that GQDs irradiated with EDA are not toxic towards MRC-5 cells, which makes them a promising, eco-friendly and safe material for sensing application.

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  - Glioblastoma (GBM) is the most common and highly lethal type of brain tumor, with poor survival despite advances in understanding its complexity. After current standard therapeutic treatment, including tumor resection, radiotherapy and concomitant chemotherapy with temozolomide, the median overall survival of patients with this type of tumor is less than 15 months. Thus, there is an urgent need for new insights into GBM molecular characteristics and progress in targeted therapy in order to improve clinical outcomes. The literature data revealed that a number of different signaling pathways are dysregulated in GBM. In this review, we intended to summarize and discuss current literature data and therapeutic modalities focused on targeting dysregulated signaling pathways in GBM. A better understanding of opportunities for targeting signaling pathways that influences malignant behavior of GBM cells might open the way for the development of novel GBM-targeted 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  - Large amounts of hazardous and toxic substances in the environment require non-toxic, cheap, easy, rapid, and sensitive methods for their detection. Blue luminescent graphene quantum dots (GQDs) were produced by electrochemical cleavage of graphite electrodes followed by gamma irradiation in the presence of ethylenediamine (EDA). Modified dots were able to detect metal ions (Co2+, Pd2+, Fe3+) due to photoluminescence quenching. The highest sensitivity was detected for the sample irradiated at a dose of 25 kGy. The limits of detection (LODs) were 1.79, 2.55, and 0.66 μmol L−1 for Co2+, Fe3+, and Pd2+, respectively. It was observed that GQDs irradiated at 200 kGy act as an ultra-sensitive turn-on probe for Malathion detection with LOD of 94 nmol L−1. Atomic force microscopy images proved the aggregation of GQDs in the presence of the investigated metal ions. Results obtained by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and LIVE/DEAD cytotoxicity test indicated that GQDs irradiated with EDA are not toxic towards MRC-5 cells, which makes them a promising, eco-friendly and safe material for sensing application.

AB  - Based on previous investigations where bis-bibenzyls isolated from liverworts showed various biological activities (cytotoxic, antimicrobial, and antiviral), we investigated their cytotoxic activity in several human cancer cell lines. From the methylene-chloride/methanol extract of the liverwort Pellia endiviifolia, three bis-bibenzyls of the perrottetin type were isolated, namely perrottetin E, 10 '-hydroxyperrottetin E, and 10,10 '-dihydroxyperrottetin E. The last two were found for the first time in this species. Their structures were resolved using 1D and 2D NMR, as well as by comparison with data in the literature. Cytotoxic activity of the isolated compounds was tested on three human leukemia cell lines, HL-60 (acute promyelocytic leukemia cells), U-937 (acute monocytic leukemia cells), and K-562 (human chronic myelogenous leukemia cells), as well as on human embryonal teratocarcinoma cell line (NT2/D1) and human glioblastoma cell lines A-172 and U-251, and compared to the previously isolated bis-bibenzyls (perrottetins) of similar structure. The isolated compounds exhibited modest activity against leukemia cells and significant activity against NT2/D1 and A-172. Overall, the most active cytotoxic compounds in this investigation were perrottetin E (1), isolated in this work from Pellia endiviifolia, and perrottetin F phenanthrene derivative (7), previously isolated from Lunularia cruciata and added for a comparison of their cytotoxic activity.

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.

AB  - Glioblastoma (GBM) is the most common, most aggressive and deadliest brain tumor. Recently, remarkable progress has been made towards understanding the cellular and molecular biology of gliomas. GBM tumor initiation, progression and relapse as well as resistance to treatments are associated with glioma stem cells (GSCs). GSCs exhibit a high proliferation rate and self-renewal capacity and the ability to differentiate into diverse cell types, generating a range of distinct cell types within the tumor, leading to cellular heterogeneity. GBM tumors may contain different subsets of GSCs, and some of them may adopt a quiescent state that protects them against chemotherapy and radiotherapy. GSCs enriched in recurrent gliomas acquire more aggressive and therapy-resistant properties, making them more malignant, able to rapidly spread. The impact of SOX transcription factors (TFs) on brain tumors has been extensively studied in the last decade. Almost all SOX genes are expressed in GBM, and their expression levels are associated with patient prognosis and survival. Numerous SOX TFs are involved in the maintenance of the stemness of GSCs or play a role in the initiation of GSC differentiation. The fine-tuning of SOX gene expression levels controls the balance between cell stemness and differentiation. Therefore, innovative therapies targeting SOX TFs are emerging as promising tools for combatting GBM. Combatting GBM has been a demanding and challenging goal for decades. The current therapeutic strategies have not yet provided a cure for GBM and have only resulted in a slight improvement in patient survival. Novel approaches will require the fine adjustment of multimodal therapeutic strategies that simultaneously target numerous hallmarks of cancer cells to win the battle against GBM.

AB  - Nowadays, a larger number of aggressive and corrosive chemical reagents as well as toxic solvents are used to achieve structural modification and cleaning of the final products. These lead to the production of residual, waste chemicals, which are often reactive, cancerogenic, and toxic to the environment. This study shows a new approach to the modification of graphene quantum dots (GQDs) using gamma irradiation where the usage of reagents was avoided. We achieved the incorporation of S and N atoms in the GQD structure by selecting an aqueous solution of L-cysteine as an irradiation medium. GQDs were exposed to gamma-irradiation at doses of 25, 50 and 200 kGy. After irradiation, the optical, structural, and morphological properties, as well as the possibility of their use as an agent in bioimaging and photodynamic therapy, were studied. We measured an enhanced quantum yield of photoluminescence with the highest dose of 25 kGy (21.60%). Both S- and N-functional groups were detected in all gamma-irradiated GQDs: amino, amide, thiol, and thione. Spin trap electron paramagnetic resonance showed that GQDs irradiated with 25 kGy can generate singlet oxygen upon illumination. Bioimaging on HeLa cells showed the best visibility for cells treated with GQDs irradiated with 25 kGy, while cytotoxicity was not detected after treatment of HeLa cells with gamma-irradiated GQDs.

abstract = "Nowadays, a larger number of aggressive and corrosive chemical reagents as well as toxic solvents are used to achieve structural modification and cleaning of the final products. These lead to the production of residual, waste chemicals, which are often reactive, cancerogenic, and toxic to the environment. This study shows a new approach to the modification of graphene quantum dots (GQDs) using gamma irradiation where the usage of reagents was avoided. We achieved the incorporation of S and N atoms in the GQD structure by selecting an aqueous solution of L-cysteine as an irradiation medium. GQDs were exposed to gamma-irradiation at doses of 25, 50 and 200 kGy. After irradiation, the optical, structural, and morphological properties, as well as the possibility of their use as an agent in bioimaging and photodynamic therapy, were studied. We measured an enhanced quantum yield of photoluminescence with the highest dose of 25 kGy (21.60%). Both S- and N-functional groups were detected in all gamma-irradiated GQDs: amino, amide, thiol, and thione. Spin trap electron paramagnetic resonance showed that GQDs irradiated with 25 kGy can generate singlet oxygen upon illumination.

AB  - Due to their low cost and possible green synthesis, high stability and resistance to photobleaching, graphene quantum dots (GQDs) can be considered as one of the class of carbon nanomaterials which may have great potential as an agent for photosensitized oxygen activation. In such a way, GQDs can be used as a theranostic agent in photodynamic therapy. In this work pristine GQDs, GQDs irradiated with gamma rays and GQDs doped with N and N, S atoms are produced using a simple, green approach. By using different techniques (AFM, HRTEM, SEM-EDS, FTIR, XRD, PL and UV-Vis) we investigated structural and optical properties of the new types of GQDs. We showed that GQDs functionalized with thiourea (GQDs-TU) completely lost the ability to produce singlet oxygen (O-1(2)) upon photoexcitation while functionalization with urea (GQDs-U) improves the capability of GQDs to produce O-1(2) upon the same conditions. Thus, presented GQDs modification with urea seems like a promising approach for the production of the efficient photosensitizer. On the opposite, GQDs-TU are efficient . OH quencher. Due to high singlet oxygen production and low cytotoxicity below 100 mu g/mL against HeLa cells, GQDs-U is a good candidate as an agent in photodynamic therapy at this concentration.

AB  - Photoactive materials called photosensitizers can be used for treatment of different types of cancer in combination with light source. In this paper, we have investigated pro-oxidant and antioxidant potentials of four graphene based nanomaterials (graphene oxide-GO, graphene quantum dots-GQDs, carbon quantum dots-CQDs and N-doped carbon quantum dots-N-CQDs) depending on the presence/absence of visible light source. Structural and optical properties of these materials and their potentials for reactive oxygen species generation/quenching are investigated by applying different microscopy and spectroscopy techniques (transmission electron microscopy, FTIR, UV-Vis, photoluminescence, electron paramagnetic resonance). Results show that all types of quantum dots has pro-oxidant and antioxidant potentials whereas GO demonstrated only moderate antioxidant effect. The best free radical scavenger is CQDs sample in the absence of light. CQDs are the best singlet oxygen generator under blue light irradiation as well. To check photo-cytotoxicity of these materials, photo-cytotoxic concentrations of the GO, GQDs, CQDs and N-CQDs were determined for three cellular lines: human rhabdomyosarcoma (RD), cell line derived from human cervix carcinoma Hep2c (HeLa) and fibroblast cell line from murine (L2OB). Cytotoxicity test has indicated that all samples are much less photocytotoxic than cis-diamminedichloroplatinum (cis-DPP). The production method and doping of quantum dots affect the photodynamic activity of tested samples very much.

AB  - Background/Aims: Guanidinoacetic acid (GAA) is an experimental dietary additive and has been reported to induce methyl depletion when provided by the diet. However, no study evaluated whether supplemental GAA affects DNA methylation, a critical epigenetic process for genome regulation. Methods: In this open-label, repeated-measure interventional trial, we evaluated the impact of 12 weeks of GAA supplementation on global DNA methylation in 14 healthy participants (8 women and 6 men, age 22.2 +/- 2.3 years, body mass index 24.8 +/- 5.7). Results: Dietary provision of GAA had no effect on global DNA methylation, with 5-methylcytosine (m5C) nonsignificantly increased by 13.4% at postadministration when averaged across participants (95% confidence interval -5.5 to 32.3; p = 0.26). Notable DNA hypomethylation (corresponding to a 5% drop in m5C) was found in 3 of 14 participants at follow-up. Conclusion: Global DNA methylation seems to be unaltered by dietary provision of 3 g of GAA per day for 12 weeks in healthy men and women.

AB  - Sox3/SOX3 is one of the earliest neural markers in vertebrates. Together with the Sox1/SOX1 and Sox2/SOX2 genes it is implicated in the regulation of stem cell identity. In the present study, we performed the first analysis of epigenetic mechanisms (DNA methylation and histone marks) involved in the regulation of the human SOX3 gene expression during RA-induced neural differentiation of NT2/D1 cells. We show that the promoter of the human SOX3 gene is extremely hypomethylated both in undifferentiated NT2/D1 cells and during the early phases of RA-induced neural differentiation. By employing chromatin immunopre-cipitation, we analyze several histone modifications across different regions of the SOX3 gene and their dynamics following initiation of differentiation. In the same timeframe we investigate profiles of selected histone marks on the promoters of human SOX1 and SOX2 genes. We demonstrate differences in histone signatures of SOX1, SOX2 and SOX3 genes. Considering the importance of SOXB1 genes in the process of neural differentiation, the present study contributes to a better understanding of epigenetic mechanisms implicated in the regulation of pluripotency maintenance and commitment towards the neural lineage.

AB  - Transcription factors OCT4 and NANOG are main constituents of a functional network that controls proliferation and pluripotency maintenance of stem cells as well as early lineage decisions. We investigated expression profiles of OCT4 and NANOG during the early phases of neural differentiation using NT2/D1 cells induced by retinoic acid as an in vitro model system of human neurogenesis. We demonstrated decrease in OCT4 and NANOG mRNA and protein levels following exposure to retinoic acid. Next, by employing chromatin immunoprecipitation, we investigated profiles of selected H3 and H2B histone marks deposited on the promoters of the OCT4 and NANOG genes. We found decline in H3K4me3, H2BK5ac, and H2BK120ac on both promoters, which paralleled the decrease in OCT4 and NANOG expression. Moreover, we found that the H2BK16ac mark is differentially enriched on these two promoters, pointing to differences in epigenetic regulation of OCT4 and NANOG gene expression. Finally, based on our data, we suggest that the early response of pluripotency genes OCT4 and NANOG to the differentiation-inducing stimuli is mediated by dynamic changes in chromatin marks, while DNA methylation is acquired in the later stages of neurogenesis.

abstract = "Transcription factors OCT4 and NANOG are main constituents of a functional network that controls proliferation and pluripotency maintenance of stem cells as well as early lineage decisions. We investigated expression profiles of OCT4 and NANOG during the early phases of neural differentiation using NT2/D1 cells induced by retinoic acid as an in vitro model system of human neurogenesis. We demonstrated decrease in OCT4 and NANOG mRNA and protein levels following exposure to retinoic acid. Next, by employing chromatin immunoprecipitation, we investigated profiles of selected H3 and H2B histone marks deposited on the promoters of the OCT4 and NANOG genes. We found decline in H3K4me3, H2BK5ac, and H2BK120ac on both promoters, which paralleled the decrease in OCT4 and NANOG expression. Moreover, we found that the H2BK16ac mark is differentially enriched on these two promoters, pointing to differences in epigenetic regulation of OCT4 and NANOG gene expression. Finally, based on our data, we suggest that the early response of pluripotency genes OCT4 and NANOG to the differentiation-inducing stimuli is mediated by dynamic changes in chromatin marks, while DNA methylation is acquired in the later stages of neurogenesis.",

AB  - Transcription factor NF-Y belongs to the embryonic stem cell transcription factor circuitry due to its role in the regulation of cell proliferation. We investigated the role of NF-Y in pluripotency maintenance using NT2/D1 cells as one of the best-characterized human embryonal carcinoma cell line. We investigated the efficiency of protein transduction and analyzed the effects of forced expression of short isoform of NF-Y A-subunit (NF-YAs) on NT2/D1 cell growth and expression of SOX2. We found that protein transduction is an efficient method for NF-Y overexpression in NT2/D1 cells. Next, we analyzed the effect of NF-YAs overexpression on NT2/D1 cell viability and detected significant reduction in cell growth. The negative effect of NF-YAs overexpression on NT2/D1 cell pluripotency maintenance was confirmed by the decrease in the level of the pluripotency marker SOX2. Finally, we checked the p53 status and determined that the NF-Y-induced inhibition of NT2/D1 cell growth is p53-independent.

AB  - Chokeberry juice was subjected to in vitro gastric digestion in the presence of food matrix in order to determine the changes in polyphenol content and antioxidant activity. Addition of food matrix immediately decreased the total phenolic content, anthocyanin content, DPPH scavenging activity as well as total reducing power by 36%, 90%, 45% and 44%, respectively. After in vitro digestion, total phenolic content, anthocyanin content and reducing power are slightly elevated, but they are still lower than in initial non-digested juice. The effect of digested juice on Caco-2 cells proliferation was also studied, and the reduction of proliferative rate by approximately 25% was determined. Our results suggested that although a large proportion of chokeberry phenolics undergo transformation during digestion they are still potent as antioxidant and antiproliferative agents.
