A narrative review about the intricate crosstalk among endometrium, adipose tissue, and neurons in endometriosis. The multifaceted role of leptin.

Endometriosis is a highly prevalent gynecological disease characterized by the presence of endometrium-like tissue outside the uterus, whose etiopathology is far from being elucidated. The most frequent complains of patients are pelvic pain and infertility. Increasing evidence supports the systemic impact of endometriosis suggesting that an intricate crosstalk among distinct organs underlies the development of the disease.

Evidence of Browning and Inflammation Features in Visceral Adipose Tissue of Women with Endometriosis.

Background: Patients with endometriosis tend to have a low body mass index, suggesting an inverse relationship between body fat and risk of disease. This is supported by evidence that miRNAs differentially expressed in endometriosis induce browning of pre-adipocytes in vitro. Thus, we hypothesize that endometriosis may underlie adipose tissue (AT) dysfunction and browning.

Metformin Prevents Endothelial Dysfunction in Endometriosis through Downregulation of ET-1 and Upregulation of eNOS.

This study aimed to evaluate if the treatment with metformin affects the morphologic structure, endothelial function, angiogenesis, inflammation and oxidation-responsive pathways in the heart of mice with surgically induced endometriosis. B6CBA/F1 mice (n = 37) were divided into four groups; Sham (S), Metformin (M), Endometriosis (E) and Metformin/Endometriosis (ME). The cross-sectional area of cardiomyocytes was assessed after Hematoxylin-Eosin staining and fibrosis after Picrosirius-Red staining.
