Neijenhuis et al. showed high miR-107 and low RAD51 expression in a subset of ovarian cancer, and demonstrated that miR-107 reduces RAD51 expression [63]; Huang et al. identified several miRNAs including miR-103 and miR-107 that are directly involved in regulating RAD51 and RAD51D using miRNA mimics screening [25]; Wang et al. showed that miR-96 reduces the levels of RAD51 and REV1 [21]; Choi et al. showed that miR-148b and miR-193b reduce RAD51 expression, and suppress the homologous recombination specifically in the G1 phase [31]. This evidence concerns the gene RAD51 and ovarian cancer.
