While working in Dr. Tallant’s lab, I am investigating whether Angiotensin-(1-7) can be used as a novel first-in-class therapy for estrogen receptor (ER) positive and human epidermal growth factor 2 (HER2) amplified breast cancer. Previous studies have demonstrated that Ang-(1-7) decreases the growth of non-small cell lung adenocarcinoma in vitro and in vivo. The decrease in tumor growth is associated with a corresponding downregulation in activated MAPK and COX2. My preliminary studies have shown that subcutaneous infusion of Ang-(1-7) reduces orthotopic HER2 amplified (BT-474) breast cancer and orthotopic ER-positive (ZR-75-1) breast cancer. In addition, it was shown that the decrease in HER2 amplified breast cancer may be due in part to a decrease in active MAPK activity, decreased COX2, and decreased VEGF. My research will also focus on the molecular mechanism of Ang-(1-7) mediated growth reduction in HER2 amplified and ER-positive breast cancer with special focus on Ang-(1-7) effect on the protein kinase B (Akt) pathway.
