MAP1LC3B and mesothelioma: Indeed, we observed autophagy induction by rapamycin and crizotinib in the mTOR/ALK-positive mesothelioma graft model, evidenced by the accumulation of LC3B in autophagosomes: 9.1% and 7.7% autophagosome-positive cells in the rapamycin and crizotinib groups, respectively, versus 2.5% in the control group.
