The expression levels of lncRNA‐MALAT1, HIF‐1α, and LC3 in different groups of endometria. A, Significant higher expression of lncRNA‐MALAT1 was found in ectopic endometrium tissues of endometriosis than in normal tissues and eutopic endometrium tissues of endometriosis. (B‐C) Representative Western blots of HIF‐1α and LC3 protein from normal endometrium, eutopic endometrium, and ectopic endometrium. D, Representative immunohistochemical images of HIF‐1α and LC3 protein localization in normal endometrium, eutopic endometrium, and ectopic endometrium. Photographs were taken at magnifications of 200× (left panels) and 800× (right panels), respectively. Left bar = 50 μm, right bar = 12.5 μm. The protein expression levels were quantified by Image J software and normalized to GAPDH protein levels. Quantitative results are expressed as the means ± SD of at least three independent experiments (**P < 0.01)
