Research Interests

The project I: Regulated Proteolysis in oncogenic ERBB/K-RAS-Mediated Tumorigenesis and Metastasis in human cancer

Dr. Tang’s laboratory studies the RAS signal transduction pathway using multiple model organisms/systems including Drosophila, transgenic mice, human cancer cell lines, and human cancer tissue specimens. As oncogenic RAS promotes the genesis of many human cancers, how best to contravene activated RAS signaling has been an intense area of investigation in the field of cancer biology for the past 30 years. Seven-In-Absentia (SINA), an E3 ubiquitin ligase, is an essential downstream component of the Drosophila RAS signal transduction pathway. The human homolog of SINA, SIAH, is a member of this evolutionarily highly conserved family of RING finger E3 ubiquitin ligases; however, the roles and regulation of SIAH-dependent proteolysis are not well understood in the context of RAS signal transduction in mammalian systems.

Dr. Tang’s lab has accumulated evidence demonstrating the importance of proper SIAH function in mammalian K-RAS signaling. We show that by inhibiting the enzymatic activity of SIAH, and thus SIAH-mediated proteolysis, RAS-mediated neoplastic transformation and tumorigenesis can be effectively blocked in human cancer cells [Can Res 67(24):1798-810, 2007; JNCI 100(22):1606-29, 2008]. Furthermore, SIAH-deficient cells have reduced MAPK signaling, suggesting that SIAH might be involved in aberrant K-RAS signaling through a regulatory feedback loop mechanism. Thus, these studies provide an initial glimpse into the significance of the SIAH E3 ubiquitin ligase-regulated proteolysis in the K-RAS pathway during tumor initiation, progression, and oncogenesis in human pancreatic cancer, lung cancer, invasive and metastatic breast cancer, and hormonal-refractory prostate cancer.

Advancing understanding of the role of SIAH E3 ligases in K-RAS signaling and, more importantly, the potential to target SIAH as a novel new anti-K-RAS and anti-cancer target in the treatment of the most aggressive and the deadliest forms of human cancers represent exciting steps forward in the fields of K-RAS signaling, cancer biology and cancer therapy. Ultimately, we hope such SIAH-based anti-cancer therapies will lead to novel and efficacious treatments for human cancer patients, especially the ones with metastatic diseases.
