Latest Patents

Hughes B De The holds a patent for a steroid/thyroid hormone receptor-related gene. This invention involves a previously isolated hepatitis B virus (HBV) integration in a 147 bp cellular DNA fragment linked to hepatocellular carcinoma (HCC). The patent describes the cloning of complementary DNA from a human liver cDNA library, revealing a cellular gene named hap. This gene exhibits a structure similar to DNA-binding hormone receptors. Notably, six out of seven hepatoma and hepatoma-derived cell lines express a 2.5 kb hap mRNA species, which is absent in normal adult and fetal livers but present in all non-hepatic tissues analyzed. The cloned DNA sequence is valuable for preparing pure hap protein and for detecting and isolating complementary DNA and RNA sequences. The hap protein is identified as a retinoic acid (RA) receptor known as RAR-.beta., which is transcriptionally up-regulated by retinoic acid.
