Abstract Objective: To investigate the effect of FTO on fibrosis of ectopic endometrial mesenchymal cells (eESCs). Methods: m6A-related genes in endometriosis (EMs) were screened and detected, using quantitative real-time polymerase chain reaction (qRT-PCR). Detection of fibrosis-related gene expression in eESCs by overexpression of FTO in a lentiviral vector. Relationship between FTO and TLR2 in eESCs predicted and validated by m6A2 Target site and MeRIP-qPCR. Protein changes in p38 were detected by Western blot. Results:FTO expression was down-regulated in EMs (P<0.05). FTO overexpression promoted fibrosis and inhibited proliferation of eESCs (P<0.05). FTO upregulated its protein level through m6A modification of TLR2 in eESCs (P<0.05). FTO promoted cell fibrosis through TLR2/p38 signaling pathway in eESCs (P<0.05). Conclusion:FTO is low expressed in EMs and upregulation of FTO promotes fibrosis of eESCs through TLR2/p38 signaling pathway.
