MTOR and cancer: The addition of CQ to Salidroside, a glycoside isolated from the root of Rhodiola rosea L., enhanced the sensitivity of hepatocellular cancer HepG2 and 97H cells to this compound and exerted a synergic effect on the growth of the mice HepG2 xenograft by suppressing the invasion and metastasis of cancer cells through the PI3K/Akt/mTOR pathway, promoting mitochondrial dysfunction and altering the ratio between the expression of pro- and anti-apoptotic proteins [80,114].
