Gut flora influences the hypothalamic-gonadal axis to regulate the pathogenesis of obesity-associated precocious puberty.

ABSTRACT: The prevalence of obesity-associated precocious puberty is gradually increasing, but the relationship between gut flora and obesity-associated precocious puberty remains unclear.We analysed the gut flora characteristics of a clinical sample of 30 girls aged 5-8 years using 16s rRNA sequencing. An obesity rat model and a rat model of gut flora transplantation were also constructed. Body weight, body length, abdominal girth, food intake, vulva opening time, and gonadal index were monitored. The secretion levels of estradiol (E2), total cholesterol (TC), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and thyroglobulin (Tg) were analyzed by ELISA. In addition, ovarian and uterine development was observed by HE staining. The mRNA and protein levels of kisspeptin-1 (Kiss-1) and go
