Ratna K. Vadlamudi, Ph.D.



The focus of Dr. Vadlamudi's research to study the molecular mechanisms by which steroid hormone estrogen signal in normal and pathological conditions such as cancer. The biological functions of estrogen are mediated by estrogen receptors (ERs), however, their signaling mechanisms are elusive. 

His research has been centered on the identification and characterization of novel coregulator proteins that modulate ER functions. 

Current research interests include: (1) characterizing the function of ER-coregulators in cancer progression (2) developing transgenic and knock-out mouse models for ER-coregulators (4) identifying novel molecular targets for therapeutic intervention (5) characterizing the role of ER coregulators in neurodegenerative disorders such as stroke and (6) development of small molecular inhibitors.
