Laboratory of Perinatal Kinesioepigenetics

The population with obesity and type 2 diabetes are rapidly increasing. Currently, more than a third of women at reproductive age were obese and another one third are overweight in the US. Regular physical activity and exercise are critical for preventing and attenuating the adverse effects of obesity and metabolic dysfunction. While “Exercise is medicine” is well recognized, the underlying cellular and molecular mechanisms linking maternal exercise and fetal development during pregnancy remains poorly defined.

Exercise and physical activity induce muscle to secrete hormones, so called exerkines, which are beneficial for glucose homeostasis particularly in women with obesity and metabolic diseases. Similarly, maternal exercise stimulates secretion of exerkines from muscle and fat, which exert biological effects on placenta. As a key organ responsible for nutrient delivery and cross-talk between mothers and their fetuses, such change in placenta is expected to have profound impacts on fetal development and exert long-term effects on the metabolic health of future generation.

My research focuses on the impact of maternal exercise, obesity and other physiological environments on fetal development and offspring health, emphasizing the epigenetic modification linking nutrients/metabolites to stem (progenitor) cell differentiation into myocytes/adipocytes. Ultimately, we aim to translate our work into clinical practice with respect to improving health outcomes for mothers and children affected by obesity and metabolic dysfunction.
