(Submitter supplied) Background: Previously, we showed that gestational arsenite (As) exposure of F0 females increases hepatic tumors in the F2 males in C3H mice. However, the mechanisms have not yet been clarified. Methods: We detected genome wide site-specific DNA methylation by using reduced representative bisulfite sequence (RRBS) method. We used the data uploaded here and those with GSE Series accession number GSE111420 (CCN and CCTt) to detect differential methyrated cytosines between control groups and arsenite groups. 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) Introduction: Hepatocellular carcinoma (HCC) is one of the most aggressive solid tumors and oncogenic pathways (e.g Akt, IGF signaling) are often activated in high proliferating HCC. Among several genetic alterations, epigenetic changes seem to be involved in the development and progression of HCC. DNA hypermethylation of promoter regions is almost always associated with transcriptional silencing and can lead to inactivation of tumor suppressor genes (TSG) in cancer cells. more...

(Submitter supplied) Genome wide DNA methylation profiling of paired adjacent and hepatocellular samples and 8 non-diseased liver samples. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs. Samples included 12 paired adjacent and 12 hepatocellular samples.

(Submitter supplied) Non-coding microRNAs (miRNAs) mainly regulate the expression of targeted genes by regulating mRNA degradation or repressing their protein translation. MiRNA microarray profiling was then performed on 218 human HCC tumors samples, 10 samples from adjacent cirrhotic non-tumoral tissue, 10 samples from healthy liver and 12 HCC cell lines. In this study we investigated which miRNAs were differentially expressed in HCC compared to cirrhotic non-tumoral tissue and healthy liver.

(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) Pregnant C3H mice were given tap water (control group) and tap water containing 85 ppm sodium arsenite from gestational day 8 to 18 (arsenic group), respectively. The DNA methylomes of sperm of F1 mice were investigated by RRBS method. The results showed that gestational arsenic exposure increased hypomethylated cytosines in active retrotransposon subfamilies. The present study has indicated environmental impacts on sperm DNA methylome establishment.

After Bonferroni adjustment, a total of 130,512 CpG sites significantly differed in methylation level in tumor compared to non-tumor tissues, with 28,017 CpG sites hypermethylated and 102,495 hypomethylated in tumor tissues. Most (60.1%) significantly hypermethylated CpG sites are located in CpG islands. more...
