多囊卵巢综合征(PCOS)是一种常见的生殖内分泌疾病,具有发病率高、病因复杂、治疗效果差的特点。多囊卵巢综合征患者经常表现出肠道生态失调;然而,其在多囊卵巢综合征病理生理中调节代谢和内分泌平衡的作用尚不清楚。在本研究中,脱氢表雄酮(DHEA)诱导的pcos样大鼠再现了肠道生态失调。在DHEA治疗期间,使用抗生素鸡尾酒来消除肠道微生物群;然而,在dhea处理的大鼠中,肠道微生物群的消耗并没有阻止PCOS表型的发生。将dhea型肠道菌群移植到假无菌接受者体内,可引起肝脏糖脂代谢紊乱和生殖激素失衡。PCOS的临床特征可能与粪便微生物群移植(FMT)受体大鼠肠道微生物的相对丰度和粪便代谢物水平有关。这些结果提示雄激素诱导的肠道菌群失调可能加重多囊卵巢综合征的代谢和内分泌功能障碍。视频摘要在线版本包含补充材料,可在10.1186/s40168-021-01046-5获得。
The characteristics of polycystic ovary syndrome (PCOS), a common reproductive endocrinal disorder, are high incidence, complicated aetiology and poor therapeutic effects. PCOS patients frequently exhibit gut dysbiosis; however, its roles in the regulation of metabolic and endocrinal balances in PCOS pathophysiology are not clear. In this study, gut dysbiosis was reproduced in dehydroepiandrosterone (DHEA)-induced PCOS-like rats. An antibiotic cocktail was used to eliminate gut microbiota during DHEA treatment; however, depletion of the gut microbiota did not prevent the occurrence of PCOS phenotypes in DHEA-treated rats. DHEA-shaped gut microbiota transplanted to pseudo germ-free recipients trigged disturbances in hepatic glucolipid metabolism and reproductive hormone imbalance. The clinical features of PCOS may be correlated with the relative abundance of gut microbes and the levels of faecal metabolites in faecal microbiota transplantation (FMT) recipient rats. These findings indicate that androgen-induced gut microbiota dysbiosis may aggravate metabolic and endocrinal malfunction in PCOS.
