GAS5 overexpression promotes apoptosis of ovarian cancer cells such as A2780, HEY, OVCAR3, and SKOV3, and increases the sensitivity of HEY and SKOV3 cells to the anticancer agent cisplatin (Gao et al., 2015; Li et al., 2016; Zhao et al., 2018; Long et al., 2019). This evidence concerns the gene GAS5 and ovarian cancer.
