The long-range objective of Dr. Tekmal’s research is to elucidate the role of hormones and growth factors and their receptors in the initiation and progression of breast, cervical and ovarian cancers. 

Using our novel aromatase transgenic mice model we have demonstrated for the first time that increased mammary estrogens leads to the induction of various preneoplastic and neoplastic changes that are similar to early breast cancer. 

Ongoing studies focus on cross-talk between local estrogen/estrogen receptor-mediated action with oncogenes, growth factors, and tumor suppressor genes to initiate/promote breast cancer as well as design and testing of novel therapeutic approaches for the prevention and treatment of breast, cervical and ovarian cancers using both in vivo and in vitro model systems.
