cDNA Encoding a Gene BOG and its Protein Product

Posted Jun 15 2010 5:00pm

Description of Invention:
Available for licensing is BOG (B5t Over-Expressed Gene) with the gene product pRb of the well-known tumor suppressor gene RB, retinoblastoma susceptibility gene. The complex formed between Rb and BOG typically does not contain E2F-1 in vivo. This binding property suggests that cells which are transformed/transfected with cDNA or other functional nucleotide sequences which encode the BOG gene product will be useful as tools for studying cell cycle control and oncogenesis.

Studies using rat liver epithelial cell (RLE) lines which are resistant to the growth inhibitory effects of TGF-beta1 and primary liver tumors have been shown to over-express BOG. Moreover, when normal RLE continuously over-express BOG the cells become transformed and the transformed cells are able to form hepatoblastoma-like tumors when transplanted into nude mice. Therefore, biologics derived from BOG may be useful as diagnostics or therapeutics.

  • Method to diagnose and treat liver cancer
  • Method to study cell cycle control and oncogenesis
  • Liver cancer therapeutics

Development Status:
The technology is currently in the pre-clinical stage of development.
