In addition, oncogenic miR-1180, miR-493-5p, and miR-31 confer DDP resistance to ovarian cancer cells through silencing secreted frizzled-related protein 1(SFRP1), BRCA2, and potassium calcium-activated channel subfamily M alpha 1 (KCNMA1), respectively (Samuel et al., 2016; Meghani et al., 2018; Gu et al., 2019). This evidence concerns the gene BRCA2 and ovarian cancer.
