    Chemotherapy and targeted therapies, including the Bcl-2 inhibitor ABT-737, may induce tumor cell autophagy. Autophagy can promote survival of cancer cells under stress and comprise a pathway of escape from cytotoxic therapies.

    Chloroquine is the generic form of the brand-name prescription medicine Aralen, which is used to prevent and treat malaria — a mosquito-borne disease caused by a parasite — and to treat. In addition to these, we analyzed the status of the expression of autophagic marker proteins like LC3-II, p62 and Beclin I in 48 h ART treated cells by western blot technique. Results of the experiments demonstrated that LC3-II, p62, Beclin I were upregulated in ART-treated cells in a dose-dependent manners Fig. 3K. 3.5. The production of reactive oxygen species was measured using CM-H2DCFDA staining. A xenograft tumor model of pancreatic cancer was created to determine the efficacy of gambogic acid and chloroquine. Gambogic acid induced the expression of LC3-II and Beclin-1 proteins in pancreatic cancer cells, whereas the expression of P62 showed a decline.

    These included cell culture analyses of viability and of autophagic and apoptotic pathway induction, as well as in vivo analyses of efficacy in multiple xenograft models. We explored the combination of ABT-737 and chloroquine, an inhibitor of autophagy, in preclinical models of SCLC.

  5. A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen.

    For these studies, we next exposed the cells to VN/12-1 in the presence of chloroquine a weak lysosome stabilizing base. Cotreatment with chloroquine resulted in enhancement of LC3B band. Beclin-1 is an important autophagy-related protein, and its upregulation correlates with induction of autophagy. 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. Chloroquine-induced autophagic vacuole accumulation and cell death in glioma cells is p53 independent. Ying Geng, * Latika Kohli, * Barbara J. Klocke, and Kevin A. Roth. Chloroquine CQ, traditionally used as an antimalarial medication, has emerged as a prospective adjunct in tumor therapy.
