This result is consistent with the previous findings of Liang et al, who found that the expression level of lncRNA‐MALAT1 was significantly higher in ectopic endometrium tissue of endometriosis when compared with the paired normal endometrial tissue from the same patient.28 More importantly, previous studies reported that hypoxia provides an important driving factor in the expression pattern of various lncRNAs including MALAT1. Here, MALAT1 is linked to endometriosis.
