In OC, hypoxia has been demonstrated to stimulate the production of miR‐9‐5p, accelerating migration, invasion, and tumor proliferation through the PI3K/AKT/mTOR/GSK3β, thereby recognizing miR‐9 as a prospective oncogenic driver and therapeutic target [201, 261, 262]. The gene discussed is GSK3B; the disease is neoplasm.
