CONTEXT Methylation changes observed in Prader-Willi syndrome (PWS) may impact global methylation as well as regional methylation status of imprinted genes on chromosome 15 (in cis) or other imprinted obesity-related genes on other chromosomes (in trans) leading to differential effects on gene expression impacting obesity phenotype unique to (PWS). OBJECTIVE Characterize the global methylatio...
The epigenetic changes in pituitary adenomas were identified by evaluating the methylation status of nine genes (RB1, p14ARF, p16INK4a, p73, TIMP-3, MGMT, DAPK, THBS1 and caspase-8) in a series of 35 tumours using methylationspecific PCR analysis plus sequencing. The series included non-functional adenomas (n=23), prolactinomas (n=6), prolactinoma plus thyroid-stimulating hormone adenoma (n=1),...
The aim of this study was to clarify the significance of DNA methylation alterations shared by cancers derived from multiple organs. We analyzed single-institutional methylome data by single-CpG-resolution Infinium assay for 1007 samples of non-cancerous tissue (N) and corresponding cancerous tissue (T) obtained from lung, stomach, kidney, breast and liver. Principal component analysis revealed...
background: colorectal cancer, the third most common type of cancer is a major cause of mortality worldwide. if colorectal cancer is detected at the early stages, the 5-year survival rate is 90%. meis1 homeobox gene is implicated in numerous solid tumors and hematological malignancies. therefore, the present study aims to investigate the methylation status of the meis1 gene in colorectal cancer...
Background: Several studies have examined the presence of DNA methylation of CpG islands in leukemia. Methylation of SOX17 and RUNX3 genes may play a role in leukemogenesis through silencing tumor suppressor genes. We investigated the methylation status of SOX17 and RUNX3 genes in patients with acute leukemia. Methods: In this case-control study, peripheral blood samples from 100 AML and 10...
Background: Stem Cell differentiation is a process composed of vast variety of factors which are controlled by a network of certain mechanisms. This study aims to determine the possible role of DNA methylation, a potent regulator of VHL, ECAD and RUNX3 genes during Erythroid differentiation driven by miR-451. Materials and Methods: To determine the methylation status of promoters and the e...
