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.
We are actively investigating the mechanisms by which estrogen and exercise affect adipose tissue. Our current research studies are addressing the following specific questions:
- 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?

Dr. Vieira-Potter obtained her undergraduate degree in Biology (minor in Chemistry) from Wheaton College in Norton, MA in 2001. She worked as an undergraduate researcher on 3T3 adipocytes, studying the basics of how lipid droplets form in those cells. She then obtained her Master’s degree in Nutrition from the University of New Hampshire, where she worked with Dr. Anthony Tagliaferro on a project seeking to understand the role of sex hormones and insulin resistance in the relationship between obesity and asthma development. She went on to complete her PhD in Nutrition (University of Illinois at Urbana Champaign, 2009) in the laboratory of Dr. Jeff Woods, and exercise immunologist. Her dissertation work demonstrated that exercise has anti-inflammatory effects in obese adipose tissue. Dr. Vieira-Potter completed a postdoctoral fellowship at the USDA Human Nutrition Research Center at Tufts in the Obesity and Metabolism laboratory (2012) and started her laboratory at the University of Missouri in 2012. She currently is an Associate Professor in the Department of Nutrition and Exercise Physiology. Her laboratory studies how exercise and estrogen affect adipose tissue metabolism. She was among the first to demonstrate that exercise reduces adipose tissue inflammation and that ovarian hormone loss increases adipose tissue inflammation. Since initiating the PhIT FAT laboratory, Dr. Vieira-Potter and her team have demonstrated that aerobic fitness is protective against metabolic complications associated menopause using a variety of animal models; current work aims to elucidate adipocyte-specific mechanisms. She has mentored 5 graduate and > 20 undergraduate students and directs the Rodent Metabolic Phenotyping Core at the MU ASRC. She has 70+ peer-reviewed publications in the area of adipose tissue/cardiometabolic disease. https://www.ncbi.nlm.nih.gov/myncbi/victoria.vieira-potter.1/bibliography/public/
