    Here we show that chloroquine, a drug that activates the stress-responsive Atm-p53 tumor-suppressor pathway, preferentially enhances the death of Myc oncogene-overexpressing primary mouse B cells and mouse embryonic fibroblasts MEFs and impairs Myc-induced lymphomagenesis in a transgenic mouse model of human Burkitt lymphoma. Chloroquine CQ inhibits degradation of p53 upregulated modulator of apoptosis PUMA protein in melanoma cells. a, b To determine the half-life of endogenous PUMA protein, control or CQ-treated melanoma cells were exposed to cycloheximide, a protein synthesis inhibitor, and cell extracts collected at different time points were blotted with PUMA antibody. Chloroquine-induced killing of Myc-overexpressing cells was blunted. Thus chloroquine induces lysosomal stress and provokes a p53-dependent cell death that does not require caspase-mediated apoptosis. These findings specifically demonstrate that intermittent chloroquine use effectively prevents cancer in Research Article Find the latest version

  4. Aug 27, 2018 There is a growing evidence that antimalarial chloroquine could be re-purposed for cancer treatment. A dozen of clinical trials have been initiated within the past 10 years to test the potential of chloroquine as an adjuvant treatment for therapy–refractory cancers including glioblastoma, one of the most aggressive human cancers. While there is considerable evidence for the efficacy and.

    In a mouse model of pancreatic tumours driven by Kras mutations, the outcome of suppressing autophagy is shown to depend on the status of p53 if p53 is intact, deletion of key autophagy genes. LC3 assay using chloroquine, an inhibitor of lysosomal acidifi- cation, and the measurement of long-lived protein degradation. Chloroquine treatment led to the accumulation of GFP-LC3 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.

    Plaquenil and Bronchospasm / Cough. DailyStrength I have always had allergies and hay fever, but no asthma. In the last few weeks I have started wheezing on exhalation. I went to my local MD and he said he believes it is a side effect of the Plaquenil. He can hear the wheezing and believes the Plaquenil is causing Bronchospasm and the cough.

    Has anyone experienced plaquenil toxicity with damage to eyes?
