Study 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 کاملSTEAP4 regulates focal adhesion kinase activation and CpG motifs within STEAP4 promoter region are frequently methylated in DU145, human androgen-independent prostate cancer cells.
The possible roles of STEAP4 in cancer progression have not been reported. In this study, we report that STEAP4 expression is able to inhibit anchorage-independent cell growth. We also demonstrate that STEAP4 associates with focal adhesion kinase (FAK) and regulate the activity of FAK through Y397 phosphorylation. Furthermore, we show that CpG sequences in STEAP4 promoter region were frequently...
متن کاملDifferential methylation of CpG islands within the dermo1 gene promoter in several cancer cell lines.
Inactivation of tumor-related genes by promoter hypermethylation is a common epigenetic event in the development of variety of tumors. Dermo1 (also called twist2) is a novel cancer-related gene which belongs to the basic helix-loop-helix (bHLH) transcription factor family. Herein, we report that dermo1 expression was sporadically abrogated in human cancer cells by transcriptional silencing asso...
متن کاملOct-1 is involved in the transcriptional repression of the von willebrand factor gene promoter.
The negative regulation of transcription of the human von Willebrand factor (vWF) gene was investigated in human umbilical vein endothelial cells (HUVECs) and HeLa cells. A fragment spanning -89 to +244 nucleotides (nt), containing the first exon, is active in HUVECs only but not in HeLa cells. The activity of this promoter is sharply reduced by mutagenesis of the GATA binding site at +221. Ext...
متن کاملThe CpG island promoter of the human proopiomelanocortin gene is methylated in nonexpressing normal tissue and tumors and represses expression.
Ectopic secretion of ACTH, from sites such as small cell lung cancer (SCLC), results in severe Cushing's syndrome. ACTH is cleaved from POMC. The syndrome may occur when the highly tissue-specific promoter of the human POMC gene (POMC) is activated. The mechanism of activation is not fully understood. This promoter is embedded within a defined CpG island, and CpG islands are usually considered ...
