Analyses of methylation status of CpG islands in promoters of miR-9 genes family in human gastric adenocarcinoma
In the recent years deregulation for microRNAs expression pattern have emerged as a possible molecular factor for carcinogenesis. It has been reported that the expression of miR-9 was down-regulated in human gastric adenocarcinoma. To figure out the molecular mechanism of this down regulation, the methylation status in promoters of miR-9 family loci were compared in the human gastric adenocarci...
متن کاملTwo Steps Methylation Specific PCR for Assessment of APC Promoter Methylation in Gastric Adenocarcinoma
Gastric Cancer (GC) is the second most common cancer in the world and a leading cause of cancer-related mortality. Methylation of promoter CpG islands (CGIs) belonging to tumor suppressor genes causes transcriptional silencing of their corresponding genes leading to carcinogenesis and other disorders. Adenomatous Polyposis Coli (APC) a tumor suppressor gene is inactivated by methylation of prom...
متن کاملStudy of promoter CpG island hypermethylation of cyclindependent kinase inhibitor gene p21waf1/cip1 on some breast carcinoma cell lines
The p21 belongs to the CIP/KIP family of CDK inhibitors involved in cell cycle arrest at specific stages of the cell cycle progression. DNA methylation is the best studied epigenetic mark that have been evidently associated to chromatin condensation, and repression of gene transcription. The CpG island hypermethylation in promoter region of certain genes occurs in cancer cells and affects tumor...

متن کاملPredicting CpG Islands and DNA Methlation in the Cow Genome Using DNA Microarray Meta-Analysis and Genome Wide Scanning
DNA methylation is a type of epigenetic changes that directly affects DNA. In mammals, DNA methylation is essential for fetal development and stem cell differentiation and this phenomenon essentially occurs within the CpG islands. In this study, two methods were used to study the DNA methylation profile of cow genome. In the first method, the DNA methylation profile of the differentially expres...
