Enhancing Hormone Therapy and Chemotherapy Sensitivity of Breast Cancer
Breast cancers are broadly classified into estrogen receptor positive (ER+) and estrogen receptor negative (ER-) subtypes. Anti-estrogens (hormone therapy) and chemotherapy are treatment options for ER+ and ER- breast cancers, respectively. However, resistance to therapies is very common, and disease recurrence is associated with the spread of the diseases to multiple organs (metastasis). Dr. Nakshatri's research lab focuses on mechanisms of resistance to anti-estrogens and chemotherapy, predicting therapy resistance at the time of diagnosis, and developing effective combination therapies, particularly for metastasis.
His group has identified and commercialized biomarkers that may predict response to anti-estrogens, demonstrating that a protein complex min a subset of breast cancer plays a role in chemotherapy resistance and metastasis-research that, in collaboration with other institutions, is currently in phase I clinical trial. Additional work included circulating biomarkers that predict the effect of breast cancer on the general well-being of a patient and a new patent application on how to treat specific subtypes of breast cancer. His group also established a culturing method to grow and genomically characterize primary tumors and metastasis at the individual level.
Dr. Nakshatri's work to identify biomarkers of disease progression is another example of how IU Indianapolis faculty are TRANSLATING RESEARCH INTO PRACTICE.
