A method for identifying a synthetic ligand for retinoic acid receptor &#x3b2; comprises providing a sample, including a synthetic compound, exposing the sample to cultured cells, wherein the cultured cells comprise RAR&#x3b2;, determining if transcriptional expression of a gene encoding RAR&#x3b2; is upregulated compared to transcriptional expression of a control gene, and choosing a sample that upregulates the expression of RAR&#x3b2; as being a synthetic ligand for RAR&#x3b2;.

Identification of a synthetic ligand for retinoic acid receptor beta

A previously isolated hepatitis B virus (HBV) integration in a 147 bp cellular DNA fragment linked to hepatocellular carcinoma (HCC) was used as a probe to clone the corresponding complementary DNA from a human liver cDNA library. Nucleotide sequence analysis revealed that the overall structure of the cellular gene, which has been named hap, is similar to that of the DNA-binding hormone receptors. Six out of seven hepatoma and hepatoma-derived cell-lines express a 2.5 kb hap mRNA species which is undetectable in normal adult and fetal livers, but present in all nonhepactic tissues analyzed. Low stringency hybridization experiments revealed the existence of hap related genes in the human genome. The cloned DNA sequence is useful in the preparation of pure hap protein and as a probe in the detection and isolation of complementary DNA and RNA sequences. The hap protein is a retinoic acid (RA) receptor identified as RAR-&bgr;.

The cloned DNA sequence is useful in the preparation of pure hap protein and as a probe in the detection and isolation of complementary DNA and RNA sequences. The hap protein is a retinoic acid (RA) receptor identified as RAR-.beta.. The RAR-.beta. gene is transcriptionally up-regulated by retinoic acid (RA) and its promoter region may contain a RARE (retinoic acid responsive element).
