    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.

    Chloroquine is a lysosomotropic weak base, which in the monoprotonated form diffuses into the lysosome, where it becomes diprotonated and becomes trapped. Protonated chloroquine then changes the lysosomal pH, thereby inhibiting autophagic degradation in the lysosomes. Pugsley, H. R. Assessing Autophagic Flux by Measuring LC3, p62, and LAMP1 Co-localization Using Multispectral Imaging Flow Cytometry. J. Vis. Exp. The expression of the autophagy markers LC3B and p62 were assessed via immunofluorescence and immunoblotting after pharmacological autophagy inhibition with chloroquine, which prevents the fusion of autophagosomes and lysosomes by increasing lysosomal pH, in HT-29 and LoVo CC cell lines.

    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.

  6. 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.

    Dec 13, 2016 The interactions of p62 and the UPS, autophagy and ubiquitinated proteins. Upon UPS inhibition, p62 is upregulated and phosphorylated on S405 and S409, which can facilitate the degradation of ubiquitinated cargoes via autophagy. p62 synthesis is induced by an increase in Nrf2 following UPS deficiency. With anti-Keap1 or anti-Lc3 or anti-p62 antibodies. c 6-OhDA induces Keap1-p62 interaction. hA-Keap1 transfected heK293T cells were treated with 6-OhDA for 6 hours. cells were then lysed and followed with hA immunoprecipitation. The endogenous p62 pulled down by Keap1 was detected by western blotting. The p62 protein recognizes toxic cellular waste, which is then scavenged by a sequestration process known as self-eating or autophagy. Lack of autophagy leads to accumulation of p62, which is not.
