(Submitter supplied) In a recent NTP study, chronic exposure of B6C3F1/N mice to Ginkgo biloba extract (GBE) resulted in a high incidence of hepatocellular carcinomas (HCC). Genome-wide promoter methylation profiling and Expression profiling on GBE-exposed HCC (2000 mg/kg group), spontaneous HCC (vehicle-control group) and age-matched vehicle control liver was performed to identify differentially methylated genes and differentially expressed genes in GBE-exposed HCC and spontaneous HCC. more...

(Submitter supplied) Epigenetic modifications, such as DNA methylation, play an important role in carcinogenesis. In a recent NTP study, chronic exposure of B6C3F1/N mice to Ginkgo biloba extract (GBE) resulted in a high incidence of hepatocellular carcinomas (HCC). Genome-wide promoter methylation profiling on GBE-exposed HCC (2000 mg/kg group), spontaneous HCC (vehicle-control group) and age-matched vehicle control liver was performed to identify differentially methylated genes in GBE-exposed HCC and spontaneous HCC. more...

(Submitter supplied) Ginkgo biloba leaf extract (GBE) is used in traditional Chinese medicine as an herbal supplement for improving memory. Exposure of B6C3F1/N mice to GBE in a 2-year National Toxicology Program (NTP) bioassay resulted in a dose-dependent increase in hepatocellular carcinomas (HCC). To identify key microRNAs that modulate GBE-induced hepatocarcinogenesis, we compared the global miRNA expression profiles in GBE-exposed HCC (GBE-HCC) and spontaneous HCC (SPNT-HCC) with age-matched vehicle control normal livers (CNTL) from B6C3F1/N mice. more...

(Submitter supplied) Background: C3H mice have been frequently used in cancer studies as animal models of spontaneous liver tumors and chemically induced hepatocellular carcinoma (HCC). Epigenetic modifications, including DNA methylation, are among pivotal control mechanisms of gene expression leading to carcinogenesis. Although information on somatic mutations in liver tumors of C3H mice is available, epigenetic aspects are yet to be clarified. more...

(Submitter supplied) Ginkgo biloba leaf extract (GBE) has been used for centuries in traditional Chinese medicine and today is used as an herbal supplement for various indications such as improving neural function, anti-oxidant and anti-cancer effects. As part of the herbal supplement industry, these compounds are largely unregulated, and may be consumed in large concentrations over extended periods of time. This is of particular concern, because the long-term effects in terms of toxicity and carcinogenicity data is lacking for many herbal products, including GBE. 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) Sorafenib is currently the standard treatment for advanced hepatocellular carcinoma (HCC). Epigenetic alterations such as DNA methylation, play a decisive role in the development and progression of HCC. To our knowledge, there are no studies that have analyzed the global DNA methylation changes in HCC cells treated with sorafenib. Using MeDip-chip technologies we analyzed sorafenib effects on the methylome of human HCC cells. more...

(Submitter supplied) Chronic exposure to aflatoxin B1 (AFB1) has, in certain regions in the world, been strongly associated with the development of hepatocellular carcinoma (HCC). AFB1 is a very potent hepatotoxic and carcinogenic mycotoxin which is frequently reported as a food contaminant. Epigenetic modifications provoked by environmental exposures, such as AFB1, may create a so called persistent "epigenetic memory" or "footprint". more...
