Methylenetetrahydrofolate reductase (MTHFR) gene polymorphism 677C>T has been shown to be a risk factor for psychiatric disorders. We investigated the genotype and allelic frequencies of MTHFR 677C>T polymorphism in the group of patients with bipolar disorder type I (BDI) (n=200) and schizophrenia (n=200), and in the control group (n=300). Odds ratio (OR)(More)
BACKGROUND Toll-like receptor (TLR) signalling begins early in subarachnoid haemorrhage (SAH), and plays a key role in inflammation following cerebral aneurysm rupture. Available studies suggest significance of endogenous first-line blockers of a TLR pathway-soluble TLR2 and 4. METHODS Eighteen patients with SAH and acute hydrocephalus underwent(More)
The term epigenetic modification denotes reversible traits of gene expression that do not include alterations to the DNA sequence. These epigenetic alterations are responsible for chromatin structure stability, genome integrity, modulation of tissue-specific gene expression, embryonic development, genomic imprinting and X-chromosome inactivation in females.(More)
Data indicates that genetic factors alone do not account for ovarian tumorigenesis, suggesting that epigenetic status additionally affects this process. Therefore, we assessed the possible contribution of polymorphic variants of genes that may affect DNA methylation to the risk of ovarian cancer incidence in the Polish population. Using PCR-RFLP and HRM(More)
Recently, several studies have demonstrated the role of vitamin D receptor (VDR) polymorphisms in the development of systemic lupus erythematosus (SLE); however, these results are inconsistent between different cohorts. Therefore, we studied the prevalence of the VDR FokI (rs2228570), BsmI (rs1544410), ApaI (rs7975232) and TaqI (rs731236) genotypes and(More)
BACKGROUND The etiology of bipolar disorder (BD) and schizophrenia is very complex. Polymorphic variants of genes encoding enzymes of the monoaminergic may be involved in development of BD and schizophrenia. Therefore, we examined the prevalence of 1958G>A polymorphism of MTHFD1 gene, encoding trifunctional folate enzyme 5,10-methylenetetrahydrofolate(More)
Data on the Val762Ala (rs1136410) polymorphism in the poly(adenosine diphosphate [ADP]-ribose) polymerase 1 (PARP-1) gene as a risk factor for various types of cancers in different ethnicities are inconsistent. We studied this association in a Caucasian population. Using high-resolution melting curve analysis (HRM), we studied the distribution of the PARP-1(More)
Expression of MIR125A is diminished in breast tumors, however the reason for the hsa-mir-125a decrease in the cancer is not known. HER2 is encoded by ERBB2, a target for hsa-miR-125a which interacts with the 3'UTR of ERBB2 mRNA. The present study reveals that a poly-morphism (rs12976445) within the pri-miR-125a sequence correlates with the amount of mature(More)
The Wnt/β-catenin signaling pathway has been considered to be a factor in the development and progression of ovarian cancer. All patients with ovarian cancer and controls were tested for BRCA1 mutations (5382incC, C61G, 4153delA) with HybProbe assays and for BRCA2 mutation (5946delT) using high-resolution melting curve analysis (HRM). Mutation carriers were(More)
