Ariella Hanker, Ph.D. Assistant Professor School Medical School Department Harold C. Simmons Comprehensive Cancer Center | Internal Medicine Graduate Programs Cancer Biology, Cell and Molecular Biology Biography Dr. Hanker received her B.Sc. in chemistry from the University of Virginia in 2004 and Ph.D. in genetics and molecular biology from the University of North Carolina at Chapel Hill in 2009. Her graduate work in the laboratory of Dr. Channing Der focused on strategies to disrupt membrane binding of the small GTPase Rheb, in an effort to block aberrant Rheb/mTOR signaling in cancer. Dr. Hanker pursued postdoctoral training in the laboratory of Dr. Carlos Arteaga at Vanderbilt University Medical Center. During this time, she was awarded a postdoctoral fellowship from the Department of Defense Breast Cancer Research Program and a career development award (K12 award) from the National Cancer Institute. Her postdoctoral studies used transgenic mouse models and human breast cancer xenografts to study mechanisms of resistance to HER2-targeted therapy in HER2+ breast cancer. More recently, Dr. Hanker identified the HER2 T798I gatekeeper mutation as a mechanism of resistance to HER2-targeted therapy in HER2-mutant breast cancer. Dr. Hanker's current work is focused on 1) therapeutic targeting of breast cancer-associated alterations, and 2) delineating mechanisms of resistance to breast cancer targeted therapies, including HER2 inhibitors, antiestrogens, PI3K/AKT inhibitors, and CDK4/6 inhibitors. Dr. Hanker joined the faculty of UT Southwestern Medical Center in 2018. Her research program is supported by grants from the National Cancer Institute and the Breast Cancer Research Foundation.
