Genes affected

HEPACAM (HGNC:26361): (hepatic and glial cell adhesion molecule) The protein encoded by this gene is a single-pass type I membrane protein that localizes to the cytoplasmic side of the cell membrane. The encoded protein acts as a homodimer and is involved in cell motility and cell-matrix interactions. The expression of this gene is downregulated or undetectable in many cancer cell lines, so this may be a tumor suppressor gene. [provided by RefSeq, Jul 2011]

HEPN1 (HGNC:34400): (hepatocellular carcinoma, down-regulated 1) This gene is expressed predominantly in the liver. Transient transfection studies show the expression of this gene significantly inhibits cell growth, suggesting a role for this gene in apoptosis. Expression of this gene is down-regulated or lost in hepatocellular carcinomas (HCC), suggesting that loss of this gene is involved in carcinogenesis of hepatocytes (PMID:12971969). This gene maps to the 3'-noncoding region of the HEPACAM gene (GeneID:220296) on the antisense strand. [provided by RefSeq, Aug 2020]
