    Chloroquine and p62


    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    P62 is not only involved in autophagy as an adaptor and in many cases, p62 is upregulated such as under proteasome inhibitor treatment under high doses and under the scenario of disturbance of Nrf2. Ab155686 staining SQSTM1/p62 autophagosome in control HeLa cells treated with ethanol 0.1% left panels and SQSTM1/p62 in HeLa cells treated with 1uM bafilomycin A1 for 18hrs right panels. The cells were fixed with methanol 5min, permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M. Each Premo™ Autophagy Sensor GFP-p62 Kit includes a vial of chloroquine diphosphate. Chloroquine has been demonstrated to inhibit autophagy by elevating lysosomal pH and therefore inhibiting the fusion of autophagosomes with lysosomes and preventing the subsequent lysosomal protein degradation.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

    Figure 1 Assesment of functional basal autophagy in vitro. A Immunoblotting of LC3B and p62 upon pharmacological autophagy inhibition. A dose-dependent increase of LC3B and p62 was observed with increasing concentrations of chloroquine. Conversely, chloroquine-treated VCPR155H/+ mice revealed progressive muscle weakness, cytoplasmic accumulation of TDP-43, ubiquitin-positive inclusion bodies and increased LC3-I/II, p62/SQSTM1, and optineurin expression levels. Our in vitro patient myoblasts studies treated with rapamycin demonstrated an overall improvement in the autophagy. 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.
