Two 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 کاملPromoter Methylation of Four Tumor Suppressor Genes in Human Papillary Thyroid Carcinoma
Background & Objective: Papillary thyroid cancer (PTC) is considered to be the most common type of thyroid malignancies. Epigenetic alteration, in which the chromatin conformation and gene expression change without changing the sequence of DNA, can occur in some tumor suppressor genes and oncogenes. Methylation is the most common type of epigenetic alterations that can be an ex...
متن کاملDNA methylation of tumor suppressor genes in hepatocellular carcinoma
The basic unit of chromatin is a nucleosome included an octamer of the four core histones and 147 base pairs of DNA. Posttranslational histones modifications affect chromatin structure resulting in gene expression changes. CpG islands hypermethylation within the gene promoter regions and the deacetylation of histone proteins are the most common epigenetic modifications. The aberrant patterns of...
متن کاملMethylation Status of SMG1 Gene Promoter in Multiple Myeloma
Background: Epigenetic modifications, such as methylation can occur in multiple myeloma. SMG1is an important gene involved in cell growth which defect in methylation of its promoter leads to reduction of cell apoptosis and uncontrolled proliferation. In this study, we identified the methylation status of the SMG1 gene promoter in patients with multiple myeloma. Methods: Methylation status of S...
متن کاملWilms' tumor suppressor gene (WT1) is expressed in primary breast tumors despite tumor-specific promoter methylation.
We analyzed Wilms' tumor suppressor 1 (WT1) expression and its regulation by promoter methylation in a panel of normal breast epithelial samples and primary carcinomas. Contrary to previous reports, WT1 protein was strongly expressed in primary carcinomas (27 of 31 tumors) but not in normal breast epithelium (1 of 20 samples). Additionally, the WT1 promoter was methylated in 6 of 19 (32%) prima...
