More recently, the protective role exerted by two miRNAs, miR-145 and miR-93-5p, in suppressing ovarian cancer cell proliferation and migration through a negative transcriptional regulation of the proto-oncogene CCND2 have been described in two different studies (Hua et al., 2019; Chen et al., 2022). Here, CCND2 is linked to ovarian cancer.
