Genome-wide promoter DNA Methylation Profiling of Hepatocellular Carcinomas Arising Either Spontaneously or due to Chronic Exposure to Ginkgo biloba Extract (GBE) in B6C3F1/N Mice [Methylation]

ABSTRACT: 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. DNA methylation alterations were correlated to the corresponding global gene expression changes to identify differentially methylated promoter regions of relevant cancer genes altered in GBE-exposed HCC compared to spontaneous HCC.
