AB  - Introduction: Single nucleotide variants (SNVs) represent important genetic risk factors for susceptibility to posttraumatic sepsis and a potential target for immunotherapy. We aimed to evaluate the association between 8 different SNVs within tumor necrosis factor alpha (TNFA), lymphotoxin alpha (LTA) and Tolllike receptor (TLR2 and TLR4) genes and the risk of posttraumatic sepsis. Methods: Nested case-control study was conducted in the emergency department of the Clinical Centre of Serbia including 228 traumatized patients (44 with sepsis and 184 without sepsis). To compare the results of trauma subjects with the data from the general population, a control group of 101 healthy persons was included in the study. Genotyping of TNFA (rs1800629 and rs361525), LTA (rs909253), TLR2 (rs3804099, rs4696480 and rs3804100), and TLR4 (rs4986790 and rs4986791) was performed for all patients within all three groups using the real-time PCR method. MutationTaster database and in silico software SIFT were used to predict the variant pathogenic effect. Results: Carriage of the G allele of the TNFA rs1800629 gene variant (OR 2.1, 95%CI 1.06-4.16) and T allele-carriage of the TLR4 rs4986791 genetic variant (OR 3.02, 95%CI 1.31-6.57) were associated with significantly higher risk of sepsis in trauma patients when compared to the general population prone to sepsis and traumatized patients without developing a sepsis, respectively. Of these two variants, only variant in TLR4 gene (rs4986791) has been labeled as disease causing by both the MutationTaster database and the in-silico software SIFT, which further supports the role of this variant in various pathologies including sepsis. For the remaining six variants no significant association with the susceptibility to sepsis was detected. Conclusions: Carriage of the G allele of the TNFA rs1800629 gene variant and T allele-carriage of the TLR4 rs4986791 genetic variant confer significant risk of posttraumatic sepsis. TLR4 gene variants (rs4986790 and rs4986791) has been labelled as disease causing.

AB  - A major limitation in the development of efficient clinical protocols for mesenchymal stromal cell (MStroC)-based tissue regeneration therapy is the low retention and survival of MStroC in injured tissue after therapeutic administration. Low oxygen concentration preconditioning (LOP) during ex vivo cultivation of MStroC, as a method for mimicking oxygenation in their physiological microenvironment, has been shown to be beneficial in clinical trials using MStroC. Introducing hypoxia-mimicking molecules into MStroC during cultivation could be an advantageous LOP strategy. MicroRNA (miRNA) drugs are good candidates for this approach. Analysis of the expression of miRNA-210 in human bone marrow-derived MStroC in conditions of acute and extended hypoxia (24 to 72 h) was performed using RT-qPCR methodology. HIF-1 alpha and HIF-2 alpha gene knockdown cell lines were generated using lentiviral transduction of short hairpin RNA (shRNA) in order to examine whether miRNA-210 expression is regulated by transcription factor HIF-1 and/or HIF-2. We detected a significant increase in miRNA-210 expression in hypoxic conditions at time points of 24, 48 and 72 h (p lt 0.05). Knocking down of HIF-1 alpha and HIF-2 alpha genes indicated involvement of both transcription factors in the elevation of miRNA-210 expression. These results point to miRNA-210 as a good candidate for a hypoxia-mimicking molecule in LOP strategy.

AB  - Introduction: Tuberculosis (TBC) is a contagious chronic respiratory disease which despite the known cause, Mycobacterium tuberculosis (Mtb), and many decades of successful therapy, remains one of the leading global health problems. Immune responses against Mtb infection involve both of types of immunity, but cellular immunity, in which certain cytokines and Th1 cells play a key role, is crucial. A better understanding of the functions of the cytokine network involved in the state and progression of TBC could identify specific molecular markers for monitoring of disease activity as well as therapy outcomes in TBC patients. Methodology: We investigated expression of TNF-alpha, IL-6 and IRAK1 genes using an RT-qPCR technique in peripheral blood mononuclear cells of 33 TBC patients and 10 healthy individuals. Results: Comparison between TBC patients and healthy individuals revealed statistically significant differences for all analyzed genes. The levels of expression of TNF-alpha and IL-6 mRNA were higher, while the level of IRAK1 mRNA was lower in the TBC group compared to controls. Moreover, a strong positive correlation was observed between TNF-alpha and IL-6 gene expression. When clinical parameters were analyzed, increased levels of TNF-alpha mRNA were detected in patients with a longer duration of therapy ( gt 2 months) compared to those with a shorter therapy duration ( lt 2 months), and in patients without anemia. Conclusions: Our results indicate that the inflammatory genes we examined play a crucial role in the pathogenesis of tuberculosis, and that the expression of the TNF-alpha gene could be a marker for monitoring the clinical effect of the ant-tuberculosis drugs during therapy.

AB  - Systemic sclerosis (SSc) is a heterogeneous multisystem autoimmune disease with unknown etiology. Numerous studies have indicated that the disease heterogeneity implies various genetic abnormalities. Considering that SSc is characterized by a strong sex bias and that the position of IRAK1 gene is on the X chromosome, we assume that variations in IRAK1 gene could explain female predominance of SSc. It was previously described that miR-146a has a role in 'fine-tuning' regulation of the TLR/NF-kB signaling pathway through down-regulation of IRAK1 gene. The aim of the present study was to analyze both variants and expression level of IRAK1 and miR-146a genes in terms of susceptibility to SSc and clinical presentation of SSc patients. We analyzed variants IRAK1 rs3027898 C  gt  A and miR-146a rs2910164 C  gt  G in 102 SSc patients and 66 healthy subjects. Genotyping was performed by Sanger sequencing. Expression level of IRAK1 mRNA and miR-146a in PBMCs was performed in subset of 50 patients and 13 healthy controls by RT-qPCR. Our results showed that there was no association between IRAK1 rs3027898 and the risk of SSc in women. However, the analysis of genotype distribution of the mir-146a rs2910164 C  gt  G variant indicated that CC genotype shows strong association with lung fibrosis and active form of the disease. When expression level of IRAK1 gene was analyzed, we detected significant downregulation of IRAK1 mRNA in SSc patients compared to controls, as well as in male compared to female patients, in patients with ACAS autoantibodies and in patients with severe skin involvement. Regarding the expression level of miR-146a, we have found significantly reduced expression in SSc patients, in patients with skin involvement and in male SSc patients. The results from this study indicate that expression of IRAK1 gene could explain phenotypic heterogeneity of SSc and may be involved in the pathogenesis of SSc due to its differential expression in certain subgroups. Our results also suggested that miR-146a rs2910164 CC genotype may be predisposing factor for development lung fibrosis and more progressive form of SSc. Results from relative expression analysis of miR-146a demonstrated that changes in the level of this miRNA may have an impact on development and clinical course of SSc.

When expression level of IRAK1 gene was analyzed, we detected significant downregulation of IRAK1 mRNA in SSc patients compared to controls, as well as in male compared to female patients, in patients with ACAS autoantibodies and in patients with severe skin involvement. Regarding the expression level of miR-146a, we have found significantly reduced expression in SSc patients, in patients with skin involvement and in male SSc patients. The results from this study indicate that expression of IRAK1 gene could explain phenotypic heterogeneity of SSc and may be involved in the pathogenesis of SSc due to its differential expression in certain subgroups. Our results also suggested that miR-146a rs2910164 CC genotype may be predisposing factor for development lung fibrosis and more progressive form of SSc. Results from relative expression analysis of miR-146a demonstrated that changes in the level of this miRNA may have an impact on development and clinical course of SSc.",

AB  - Primary ciliary dyskinesia (PCD) is a rare inherited autosomal recessive or X-linked disorder that mainly affects lungs. Dysfunction of respiratory cilia causes symptoms such as chronic rhinosinusitis, coughing, rhinitis, conductive hearing loss and recurrent lung infections with bronchiectasis. It is now well known that pathogenic genetic changes lead to ciliary dysfunction. Here we report usage of clinical-exome based NGS approach in order to reveal underlying genetic causes in cohort of 21 patient with diagnosis of PCD. By detecting 18 (12 novel) potentially pathogenic genetic variants, we established the genetic cause of 11 (9 unrelated) patients. Genetic variants were detected in six PCD disease-causing genes, as well as in SPAG16 and SPAG17 genes, that were not detected in PCD patients so far, but were related to some symptoms of PCD. The most frequently mutated gene in our cohort was DNAH5 (27.77%). Identified variants were in homozygous, compound heterozygous and trans-heterozygous state. For detailed characterization of one novel homozygous genetic variant in DNAI1 gene (c. 947_948insG, p. Thr318TyrfsTer11), RT-qPCR and Western Blot analysis were performed. Molecular diagnostic approach applied in this study enables analysis of 29 PCD disease-causing and related genes. It resulted in mutation detection rate of 50% and enabled discovery of twelve novel mutations and pointed two possible novel PCD candidate genes.

AB  - Background: Intracranial germinomas (ICG) are uncommon brain neoplasms with extremely rare familial occurrence. Because ICG invades the hypothalamus and/or pituitary, endocrine dysfunction is one of the common determinants of these tumours. We present two brothers with a history of ICG. Patient 1 is a 25-year-old male who suffered from weakness of the right half of his body at the age of 18 years. Cranial MRI revealed a mass lesion in the left thalamus. He underwent neurosurgery, and the tumour was removed completely. Histopathological (HP) and immunohistochemical analyses verified the diagnosis of pure germinoma. He experienced complete remission of the tumour after radiation therapy. At the age of 22 years a diagnosis of isolated growth hormone deficiency (IGHD) was established and GH replacement was initiated. Molecular genetic analysis of the tumour tissue detected the mutation within exon 2 in KRAS gene. Patient 2 is a 20-year-old man who presented with diabetes insipidus at the age of 12 years. MRI detected tumour in the third ventricle and pineal region. After endoscopic tumour biopsy the HP diagnosis was pure germinoma. He received chemotherapy followed by radiotherapy and was treated with GH during childhood. At the age of 18 years GH replacement was reintroduced. A six-month follow-up during the subsequent two years in both brothers demonstrated the IGF1 normalisation with no MRI signs of tumour recurrence. Conclusion: To the best of our knowledge, so far only six reports have been published related to familial ICG. The presented two brothers are the first report of familial ICG case outside Japan. They have been treated successfully with GH therapy in adulthood.

AB  - Genetic predisposition to systemic sclerosis (SSc) has still not been fully revealed. Interleukin-6 (IL-6) is a mediator of T cell proliferation and fibrotic events in SSc. Polymorphisms in the IL-6 are found to be important in susceptibility to development of SSc. We aimed to assess the frequency of -174 C/G of IL-6 gene polymorphism in SSc patients and healthy controls, as well as correlation with disease manifestations. In the case-control study, 102 patients with SSc and 93 controls were included. PCR-RFLP method was performed for genotyping promotor variants -174 C/G of IL-6 gene. The expression level of IL-6 was determined by qRT-PCR on subset of 50 patients and 13 healthy controls with different IL-6 genotypes. We used UCLA GIT 2.0 questionnaire to assess gastrointestinal involvement in SSc patients. The expression level of IL-6 gene was significantly higher in patients with SSc in comparison with healthy controls (p  lt  0.05). Carriers of C-allele of IL-6 gene compared to those with G allele, showed higher expression of IL-6 gene (95.8 vs. 41.2, p  lt  0.05), higher GIT total score (0.85 vs. 0.5, p  lt  0.05) and higher distension scale score (1.4 +/- 0.9 vs. 0.78 +/- 0.8, p = 0.05). No significant differences in genotype distribution and allele frequency were observed between patients and controls. The expression of IL6 gene varies significantly during the course of SSc. The IL-6 gene variant -174 C/G (presence of C-allele) is associated with higher IL-6 gene expression and greater GIT impairment in patients with SSc.
