요약Obesity is a prevalent, systemic disease with deleterious effects on the female reproductive tract, including predisposing to abnormal uterine bleeding, decreasing fertility, and increasing the risk of endometrial cancer. Here, we sought to understand the effects of excess adipose on the benign endometrium. We developed a physiologic in vitro coculture system consisting of multicellular organoids of the benign human endometrium and adipose spheroids in the presence of estradiol, progesterone, and testosterone to mimic the menstrual cycle. Gene expression analysis of endometrial organoids under high adiposity conditions revealed downregulation of genes normally expressed in secretory endometrium, suggestive of an altered progesterone response. Genes associated with ion homeostasis and detoxification of reactive oxygen species were also downregulated, including the metallothionein (MT) family of genes. We demonstrated that MT gene expression in endometrial organoids was regulated by progesterone specifically in the epithelial cells, not in the stromal cells, and that progesterone receptor is recruited to the promoters of MT genes in endometrial epithelial cells. We illustrated the impact of MT dysregulation in the endometrium by silencing MT genes in endometrial epithelial cells, resulting in increased DNA damage. We examined native human endometrial tissue samples from premenopausal women with and without obesity to determine how MT expression correlates with obesity. Endometria from obese women displayed increased MT expression and oxidative damage in the endometrial stroma and not in the epithelium. Here, we show that the mechanism of MT regulation differs in endometrial epithelial and stromal cells. Our results reveal that exposing the endometrium to high adiposity can compromise the protective effects of progesterone, dysregulate MT genes in the endometrial epithelium, and leave the endometrium vulnerable to ROS-induced DNA damage. This study sheds light on the intricate interplay between adiposity and endometrial physiology. High adiposity or obesity can alter MT expression through different mechanisms: decreased progesterone response in the epithelial cells and increased oxidative stress in the stroma.
