Dr. Phay has two main research projects. The first is examining a novel AMPK activator for the treatment of thyroid cancer. Dr. Phay's research has shown in multiple human thyroid cancer cell lines that OSU-53 has inhibited growth at concentrations equal or lower than in breast cancer cells, and a dose and time-dependent activation of AMPK. He is currently studying the mechanism of action to potentially use synergistically with known BRAF inhibitors. The second research project is creating a molecular imaging agent for medullary thyroid cancer (MTC) and parathyroid tumors. The calcium sensing-receptor (CaSR) is expressed primarily on parathyroids, thyroid C-cells, and the kidney, as well as in MTC. Further development may allow pre-operative and intra-operative detection to improve surgical outcomes.
