RESEARCH

Dr. Gangadhara Reddy Sareddy is currently employed at The University of Texas Health at San Antonio, in the Department of Obstetrics and Gynecology. He attended Sri Krishnadevaraya University (India) and received his Bachelors in Biology, followed by Masters in Biochemistry. He received his Ph.D. in Animal Sciences from the University of Hyderabad (India). Dr. Sareddy studies are focused on hormonal signaling and epigenetic mechanisms in glioblastoma and gynecologic malignancies. Dr. Sareddy’s current research interest include: 1) understanding the significance of histone lysine demethylase KDM1A and nuclear receptor signaling in glioma stem cells and hypoxia 2) studying the tumor suppressor functions of estrogen receptor beta signaling in ovarian cancer progression and therapy resistance.
