Estrogen deficiency leads to excessive fat accumulation and impairs adipocyte function, while adipose tissue in obese individuals shows altered expression of estrogen receptors and synthesis enzymes.
Menopause-related decline in estrogen levels is accompanied by a change in adipose tissue distribution from a gynoid to an android and an increased prevalence of obesity in women. These unfavorable phenomena can be partially restored by hormone replacement therapy, suggesting a significant role for estrogen in the regulation of adipocytes' function. Indeed, preclinical studies proved the involvement of these hormones in adipose tissue development, metabolism, and inflammatory activity. However, the relationship between estrogen and obesity is bidirectional. On the one hand-their deficiency leads to excessive fat accumulation and impairs adipocyte function, on the other-adipose tissue of obese individuals is characterized by altered expression of estrogen receptors and key enzymes involved in their synthesis. This narrative review aims to summarize the role of estrogen in adipose tissue development, physiology, and in obesity-related dysfunction. Firstly, the estrogen classification, synthesis, and modes of action are presented. Next, their role in regulating adipogenesis and adipose tissue activity in health and the course of obesity is described. Finally, the potential therapeutic applications of estrogen and its derivates in obesity treatment are discussed.
Alina Kuryłowicz (Fri,) conducted a review in Obesity and menopause-related adipose tissue dysfunction. Estrogen was evaluated. Estrogen deficiency leads to excessive fat accumulation and impairs adipocyte function, while adipose tissue in obese individuals shows altered expression of estrogen receptors and synthesis enzymes.
