MTOR and ovarian cancer: Dong et al. have reported that the expression levels of lncRNA GAS5 and PTEN are downregulated in ovarian cancer tissues and cell lines; however, the expression of miR-96-5p is upregulated; GAS5 overexpression sponges miR-96-5p expression, leading to regulation of PI3K/Akt/mTOR and decreased proliferation of ovarian cancer cells (Dong et al., 2021[27]).
