abstractText | We have previously isolated from a human hepatocellular carcinoma a hepatitis B virus integration in a 147-base-pair cellular DNA fragment, similar to steroid- and c-erb-A/thyroid-hormone receptor genes. We have now cloned the corresponding complementary DNA from a human-liver cDNA library. Nucleotide sequence analysis revealed that the overall structure of the cellular gene, which we have named hap, is similar to that of the DNA-binding hormone receptors. That is, it displays two highly conserved regions identified as the putative DNA-binding and hormone-binding domains of the c-erb A/steroid receptors. Six out of seven hepatoma and hepatoma-derived cell-lines express a 2.5-kilobase (kb) hap messenger RNA species which is undetectable in normal adult and fetal livers but present in all non-hepatic tissues analysed. The data suggest that the hap gene product may be a novel ligand-responsive regulatory protein whose inappropriate expression in liver may relate to the hepatocellular carcinogenesis. |
