First, EGFR overexpressing tumour cells, high levels of STAT3 activity, loss of caveolin-1, Akt- and Myc- driven tumour cells, and argininosuccinate synthetase enzyme deficiency are all associated with a high autophagy dependency and are therefore more sensitive to CQ administration [16, 28, 119, 127–129]. This evidence concerns the gene CAV1 and neoplasm.
