DNA 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 کاملScreening of Tumor Suppressor Genes in Metastatic Colorectal Cancer
Most tumor suppressor genes are commonly inactivated in the development of colorectal cancer (CRC). The activation of tumor suppressor genes may be beneficial to suppress the development and metastasis of CRC. This study analyzed genes expression and methylation levels in different stages of CRC. Genes with downregulated mRNA expression and upregulated methylation level in advanced CRC were scr...
متن کاملMethylation-Independent Silencing of the Tumor Suppressor
The tumor suppressor gene INK4b (p15) is silenced by CpG island hypermethylation in most acute myelogenous leukemias (AML), and this epigenetic phenomenon can be reversed by treatment with hypomethylating agents. Thus far, it was not investigated whether INK4b is hypermethylated in all cytogenetic subtypes of AML. A comparison of levels of INK4b methylation in AML with the three most common cyt...

متن کاملASPP2 is a haploinsufficient tumor suppressor that cooperates with p53 to suppress tumor growth.
ASPP2 stimulates the apoptotic function of the p53 family in vivo. We show here that ASPP2-/- pups died before weaning. This postnatal lethality was significantly enhanced in p53+/- background and both deletions are synthetic lethal. ASPP2+/- mice developed spontaneous tumors. The tumor onset was accelerated by gamma-irradiation or in p53+/- background. Tumors derived from ASPP2+/- mice retaine...
