OBJECTIVE It has been reported that aberrant DNA methylation can be associated with HPV infection and cervical tumorigenesis. The aim of this study was to evaluate the possibility that polymorphic variants of genes that may affect DNA methylation status are associated with the risk of cervical cancer in the Polish population. DESIGN AND METHOD Employing(More)
Carcinogenesis may result from abnormal methylation of cancer-related genes regulatory sequence. Though, the polymorphic variants of genes encoding enzymes of folate and methionine metabolism may have an effect on DNA methylation. Using PCR-RFLPs, we examined the polymorphism distribution of genes encoding methionine synthase (MTR);(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)
The aetiology of non-syndromic cleft lip with or without cleft palate (CL/P) is very complex. It has been shown that polymorphic variants of genes encoding key proteins of folate and methionine metabolism might be important maternal risk factors of having a child with this craniofacial anomaly. Therefore, in our study, mothers with CL/P children as well as(More)
BACKGROUND The role of vitamin D receptor (VDR) single-nucleotide polymorphisms (SNPs) in ovarian cancer has been studied in various populations; however, these results are discordant between different ethnicities. METHOD Using the polymerase chain reaction-restriction fragment length polymorphism method, we studied the prevalence of the VDR FokI(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)
Tooth agenesis is one of the most common dental anomalies, with a complex and not yet fully elucidated aetiology. Given the crucial role of the Wnt signalling pathway during tooth development, the purpose of this study was to determine whether nucleotide variants of genes encoding components of this signalling pathway might be associated with hypodontia and(More)
Studies have demonstrated that changes in DNA methylation of cancer related genes can be an elementary process accounting for ovarian tumorigenesis. Therefore, we evaluated the possible association of single nucleotide polymorphisms (SNPs) of DNA methyltransferases (DNMTs) genes, including DNMT1, DNMT3B, and DNMT3A, with ovarian cancer development in the(More)
Identification of susceptibility genes in systemic lupus erythematosus (SLE) has recently become a topic of interest. The IL-10 promoter contains three single base-pair substitutions at −627C > A, −854C > T and −1117G > A. These single base-pair substitutions produce three different haplotypes, GCC, ACC and ATA, which affect IL-10 expression. We examined(More)
BACKGROUND Non-syndromic isolated cleft lip with or without cleft palate (NCL/P) is a common congenital anomaly in humans, the aetiology of which is complex and associated with both genetic and environmental factors. It has been reported that maternal nutritional factors are likely to play a major role in development of NCL/P in the embryo. OBJECTIVE As(More)
