Alterations of DNA methylation and histone modifications contribute to gene silencing in hepatocellular carcinomas
20 Jun 2007
Abstract excerpt
AIM: The aim of the present study was to examine DNA methylation and histone modification changes in hepatocellular carcinomas (HCC). METHODS: DNA methylation in the P16, RASSF1a, progesterone receptor (PGR) and estrogen receptor alpha (ERalpha) promoters was determined by quantitative bisulfite-pyrosequencing technique in HCC patients. Histone H3-lysine (K) 4, H3-K9 and H3-K27 modifications in all these four...
