MAP1LC3B and endometriosis: In contrast to the reduced expression of LC3B protein in lesions obtained from the mouse model of endometriosis (relative to uterine horns isolated from the same diseased mice), we identified an increase in LC3B levels in epithelial cells of endometriotic lesions and in eutopic endometria of endometriosis patients compared with endometrium from controls using immunohistochemistry.
