A recent study by Zheng et al. [40] showed that in endometriosis, an estrogen-dependent disorder similar to malignant tumours regarding biological behaviour, miR-429 facilitates proliferation, migration, and invasiveness of endometrial stromal cells by modulating the HIF1A inhibitor-mediated HIF1A/VEGF signalling pathway. This evidence concerns the gene HIF1A and endometriosis.
