We are the PhIT FAT laboratory group, which stands for: Physiological and Immunological Techniques to study the Function of Adipose Tissue. Specifically, we are interested in learning how diet and exercise behaviors can positively affect fat (i.e., “fit fat”). We are passionate about this area of study because a multitude of studies have shown that adipose tissue health in an important predictor of systemic metabolic health and thus, can be directly targeted to prevent and mitigate cardiometabolic diseases (e.g., obesity, diabetes, and cardiovascular disease). Our work has shown that exercise can reduce adipose tissue inflammation and insulin resistance, and improve adipose tissue mitochondrial function. We have also shown that loss of ovarian hormone production, a natural part of the aging process in women that coincides with a significant reduction in physical activity, increases adipose tissue inflammation, causes insulin resistance, and may adversely affect adipose tissue mitochondria.
- What role does estrogen receptor beta signaling play in mediating adipose tissue-specific metabolic benefits?
- What are the brain-specific mechanisms by which estrogen affects physical activity?
- Can maternal exercise mitigate the adverse epigenetic effects of environmental estrogens on physical activity and metabolic dysfunction?
- What is the mechanism by which soy phytoestrogens improve adipose tissue metabolism?
