The long non-coding RNAs (lncRNAs) that function as molecular sponges of miRNAs in endometriosis are: H19 [28], CDKN2B-AS1 [31], LINC01541 [35], LINC01116 [32], SNHG4 [36], LINC01018 [37], SMIM25 [37], MALAT1 [38], LINC00261 [39], and PCAT1 [40] (Figure 1). This evidence concerns the gene H19 and endometriosis.
