In my research we aim to identify the mechanisms by which cancer cells develop resistance to available anti-cancer therapies, and how to re-sensitize them. Over the course of last five years, we have discovered a growth hormone (GH) regulated axis in driving drug efflux, phenotype switch, and drug sequestration in intracellular compartments in human melanoma. We have also found that drug-resistant human melanoma liver cancer, and pancreatic cancer can be re-sensitized to chemotherapy by a concomitant inhibition of the GH receptors (GHR) on these tumors. My research provides the mechanistic groundwork which upholds the translational approach to treat GH responsive human cancers with a combination of GHR antagonists and anti-cancer drugs. In addition, we are involved in multiple peptide-based collaborative drug-discovery projects.
