(Submitter supplied) Multiple carcinogenesis is one of the major characteristics of human hepatocellular carcinoma (HCC). The history of multiple tumors, i.e., whether they are derived from a common precancerous or cancerous ancestor or individually from hepatocytes, is a major issue. Multiple HCC is clinically classified into intratumor metastasis (IM) and multicentric carcinogenesis (MC). Molecular markers differentiating IM and MC are of interest to clinical practitioners because clinical diagnosis of IM and MC often leads to different therapies. more...

(Submitter supplied) Introduction: According to the clonal model of tumor evolution, trunk alterations arise at early stages and are ubiquitous. Through the characterization of early stages of hepatocarcinogenesis, we aimed to identify trunk alterations in HCC and study their intra- and inter-tumor distribution in more advanced lesions. Methods: 151 samples representing the multi-step process of hepatocarcinogenesis were analyzed by targeted-sequencing and SNP array. more...

(Submitter supplied) Hepatocellular carcinoma (HCC) is a heterogeneous disease with a variety of etiological factors, and ranks as the second leading cause of cancer-related mortality worldwide due to multifocal recurrence. Comprehensive molecular evaluation of HCC by multiplatform analysis defined three major subtypes: (1) mitogenic and stem cell-like tumors with chromosomal instability; (2) CTNNB1-mutated tumors displaying DNA hypermethylation; and (3) metabolic syndrome-associated tumors, which included an immunogenic subgroup characterized by macrophage infiltration and favorable prognosis. 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) Background & Aims. Resection of hepatocellular carcinoma (HCC) tumors by partial hepatectomy (PHx) is associated with promoting hepatocarcinogenesis. We have previously reported that PHx promotes hepatocarcinogenesis in the Mdr2-knockout (Mdr2-KO) mouse, a model for inflammation-mediated HCC. Now, we explored the molecular mechanisms underlying the tumor-promoting effect of PHx in these mice. Methods. more...
