Experimental studies have shown that when using DNA damage drugs such as cisplatin or drugs targeting autophagy regulators like Pt-dIns3K inhibitor LY294002 and mTOR inhibitor rapamycin acting on breast cancer cells 67NR and 4T1 in mice, can enhance the sensitivity of cancer cells to these drugs when chloroquine is applied in combination [73]. Here, MTOR is linked to breast cancer.
