■ Research Summary

The research focus of our laboratory is the mechanism of nuclear receptor-mediated transcription. We have discovered several new proteins, called transcriptional coactivators, which interact with the activated nuclear receptors, facilitate transcription complex formation, and help to recruit basal transcription machinery including RNA polymerase II to the promoter. We have recently discovered a coactivator called CCAR1 which acts as a physical link between p160 coactivators and Mediator complex and thereby facilitates recruitment of RNA polymerase II to the promoter of nuclear receptor target genes. The study of coactivators has recently become one of the most exciting and fast-moving areas of the nuclear receptor and gene regulation fields; it provides an exciting opportunity to extend our understanding of the mechanism of transcriptional enhancement by steroid hormones. In addition to their roles in normal function, steroid hormones play crucial roles in many types of cancer; both the hormones and their synthetic antagonists are used in therapy for many types of cancer. A more complete understanding of how these hormones and their receptors and coactivators regulate gene expression should provide new insights into cancer biology and suggest new strategies for therapy.
