    Chloroquine is a lysosomotropic agent that causes marked changes in intracellular protein processing and trafficking and extensive autophagic vacuole formation. Chloroquine may be cytotoxic and has been used as a model of lysosomal-dependent cell death. Apr 19, 2012 The lysosomotropic agent chloroquine CQ is an alkylamine that accumulates in the lysosome and neutralizes the lysosomal acidity by its weak base property, 22 thereby reducing lysosomal activity. While the proteasome inhibitors MG132 and bortezomib Velcade had no effect on the levels of mutant p53 protein, cathepsin inhibitor E64d and lysosomal inhibitors ammonium chloride NH 4 Cl and chloroquine ClQ further stabilized mutant p53 levels in ES-2 cells, suggesting that mutant p53 might be continuously degraded through the lysosomal pathway even under nonconfluent growth conditions Fig. 3A.

  4. Activity of lysosomal enzymes such as proteases and nucleases. Moreover, the increased pH deact ivates P-gp in lysosomal mem-brane and finally leads to the drug efflux from lysosomes 17,18, 2 it can act as an osmotic agent increasing the osmotic pressure of the endosomes resulting in swelling and rupture of endosomal membrane 16.

    Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion. Induction of apoptosis is one of the mechanisms underlying the effects of chloroquine on suppressing glioma cell growth and viability. siRNA-mediated downregulation of p53 in wild-type but not mutant p53 glioblastoma cells substantially impaired chloroquine-induced apoptosis. Chloroquine-induced cell death in primary MEFs and human colorectal cancer cells was dependent upon p53, but not upon the p53 modulators Atm or Arf. Accordingly, chloroquine impaired spontaneous lymphoma development in Atm-deficient mice, a mouse model of ataxia telangiectasia, but not in p53-deficient mice.
