CuB can induce cancer cell apoptosis by inhibiting pathways such as JAK/STAT and PI3K/Akt and the expression of apoptosis-related proteins; arrest the cell cycle at the G2/M or S phase, impeding cancer cell proliferation; and induce autophagy via ROS production and DNA damage and suppression of the AKT/mTOR pathway. The gene discussed is MTOR; the disease is cancer.
