Dr. Dulin’s laboratory investigates the signaling mechanisms of TGF-beta-induced myofibroblast differentiation as related to pathogenesis of pulmonary fibrosis, using cell culture and animal models of the disease. His studies have described the critical role for serum response factor (SRF) in myofibroblast differentiation and pulmonary fibrosis, as well as the control of this pathway by actin and microtubule dynamics. The other direction of Dr. Dulin research relates to the basic studies on the biological function of the regulators of G protein signaling (RGS) proteins, focusing on RGS3 member of the family. His group has shown that RGS3 regulates the signaling mediated by heterotrimeric Gi and Gq proteins, as well as non-canonically of TGF-beta signaling. Together with Dr. Anne Sperling, they established the role of RGS3 in control of T cell migration and T cell – mediated inflammation, using knock-down and knockout approaches. His current studies focus on the function of endogenous RGS3 as related to cancer cell growth, migration and EMT.
