Obesity is a risk factor for the development of hormone receptor-positive (HR+) post-menopausal breast cancer and possibly triple negative breast cancer. Moreover, obesity is associated with poor outcomes for patients with breast cancer. Dr. Dannenberg’s team was the first to show that obesity causes an inflammatory state with related molecular changes in the human breast. This very recent finding builds upon preclinical studies. The researchers’ ongoing work is focused on determining the mechanisms (cellular, molecular) by which obesity-related breast inflammation occurs and defining the inflammation-related mechanisms that drive tumor formation and progression. They are also identifying biomarkers in blood and urine that reflect obesity-related adipose tissue inflammation, as well as utilizing established preclinical models to develop strategies to reverse obesity-related inflammation with the ultimate goal of reducing the risk of breast cancer. Positive preclinical findings provide the basis for human studies which have already been initiated.
A variety of inflammatory mediators including the products of cyclooxygenase (COX) enzymes stimulate the formation of aromatase, the enzyme that makes estrogen (this female hormone can drive breast cancer formation and growth). During the next year, Dr. Dannenberg will carry out mechanistic studies to explain the link between obesity and breast inflammation with an emphasis on aromatase. Additionally, his team will attempt to develop strategies to reverse obesity-related inflammation with the ultimate goal of reducing the risk of breast cancer.
