Based upon bioinformatic programs such as TargetScan21 and mirDIP22 which predict miRNA binding target transcripts, both macrophage migration inhibitory (MIF)23 and tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein zeta (YWHAZ)24 have been proposed targets of miR-451a which have been examined with respect to endometriosis pathophysiology. Here, YWHAZ is linked to endometriosis.
