Metformin inhibits the viability of paclitaxel ovarian cancer cells, increases the expression of SNHG7, and promotes autophagy in ovarian cancer cells; Metformin enhances the sensitivity of ovarian cancer cells to paclitaxel by regulating the SNHG7/miR-3127-5p axis to mediate autophagy (Yu et al., 2022). This evidence concerns the gene SNHG7 and ovarian carcinoma.
