    Autophagy-related proteins Fig. 1D and a resultant high degree of autophagy inhibition Supplementary Fig. S2B. Because chloroquine is a potent autophagy inhibitor that is FDA-approved and available for rapid translation to pedi-atric clinical trials, we evaluated its effects on our CNS tumor cells. Several molecular markers of autophagy have been studied to date but the conversion of LC3-I to LC3-II via phosphatidylethanolamine PE conjugation has been accepted as the gold standard for autophagosome formation. p62/SQSTM1 is also important since it is a substrate for LC3 which facilitates selective degradation during autophagy. Methyladenine is a PI3K inhibitor. 3-Methyladenine is a widely used inhibitor of autophagy via its inhibitory effect on class III PI3K. 3-Methyladenine 0-10 mM; 0-48 hours induces caspase-dependent cell death in HeLa cells in a time-and dose-dependent manner.

  4. The LC3-II/I ratio reflects the conversion of the protein from the cytosolic form to the autophagosome associated form upon autophagy activation and was also calculated and showed significant increases for both bafilomycin and chloroquine treatments, although chloroquine was statistically further increased, albeit modestly, from bafilomycin.

    • Inhibition of autophagy with bafilomycin and chloroquine..
    • Methyladenine 3-MA Autophagy/PI3K Inhibitor..
    • Chloroquine inhibits autophagic flux by decreasing autophagosome..

    Classic autophagy inhibitors 3-methyladenine 3-MA and chloroquine CQ can inhibit lung and colon cancers and thus have potential for tumor treatment 16–18. The small alkaline molecule CQ can accumulate in lysosomes, which will change the lysosome acidity, causing reduced hydrolysis. Chloroquine-mediated inhibition of autophagy has been demonstrated in melanoma. Heat shock protein 90 Hsp 90 is an important molecular chaperone involved in protein folding and a regulator protein involved in the cellular response to metabolic stress that may be a useful target in cancer cells 19, 20. 17-DMAG, an analogue of. Deacetylase inhibitor vorinostat SAHA 5. Chloroquine treatment of cells leads to accumulation of light chain 3-II LC3-II 1-3. This autophagy marker resides within autophagosomal membranes during the autophagic process and is degraded upon fusion with lysosomes. Chloroquine inhibition of these fusion
