We first predicted that LINC00152 was a potential target of miR‐125b, as the same binding site was also found in MCL‐1 and miR‐125b, which had a verified targeting relationship.14 LINC00152 was located in the cytoplasm, just as observed with miR‐125b and MCL‐1, which provides the necessary conditions for endogenous competition.14, 35 Second, we proved that miR‐125b was negatively correlated with LINC00152 in ovarian cancer tissues, while MCL‐1 was positively correlated. This evidence concerns the gene MCL1 and ovarian carcinoma.
