(Submitter supplied) Alcohol is a major risk factor for hepatocellular carcinoma (HCC) although the mechanisms underlying the alcohol-related liver carcinogenesis are still poorly understood. Alcohol is known to increase hepatocarcinogenesis possibly by inducing aberrant DNA methylation through the reduced provision of methyl groups within the hepatic one-carbon metabolism. Whether the epigenetically-regulated pathways in alcohol-associated HCC can be reversible or modifiable by nutritional factors is unknown. more...

(Submitter supplied) 61 human HCCs were analyzed for genome-wide gene expression. Samples were collected at two sites in Germany, Heidelberg (HD) and Hannover (N). The Heidelberg Collection include 40 independent HCC: 19 liver resections and 17 explant liver specimen (4 not determined); median age at surgery was 57 years (range, 16-78), and the male/female ratio was 3:1. All diagnoses were confirmed by histological reevaluation, and use of the samples was approved by the local ethics committee. more...

(Submitter supplied) Genome wide DNA methylation profiling of primary HCC tumors and their non-tumor tissue counterparts. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in 20 paired tumor and non-tumor tissues which were obtained from HCC patients who underwent surgery.

(Submitter supplied) Hepatocellular carcinoma (HCC) is one of the most common and lethal cancers worldwide and has a poor prognosis. Promoters represent an essential regulatory element of gene transcription in human genome. In order to understand the promoter methylation in relation with gene transcription in HCCs, We applied a liquid hybridization capture-based bisulfite sequencing (LHC-BS) approach to examine the promoter methylome of HCCs, for which we customized 150,407 capture probes and enabled coverage of 91.8% of the RefSeq gene promoters within human genome. more...

(Submitter supplied) Emerging evidences indicate that microRNAs (miRNAs) are often deregulated and have fundamental roles in hepatocellular carcinoma (HCC). However, the mechanism underlying miRNA dysregulation in HCC is still elusive. In this report, we used an integrated analysis strategy combining methylated DNA immunoprecipitation chip (MeDIP-chip) and miRNA expression microarray data to study the correlation between aberrant methylation and dysregulation of miRNA in HCC. more...
