    Lysosomal inhibitor chloroquine


    In MDA-MB-231 cells, immunolocalization and brefeldin A protein transport blocking studies revealed that there was a propensity for newly synthesized Cx43 to be transported to lysosomes. On the other hand, light and electron microscopic analysis of BICR-M1R cells showed that Cx43 gap junctions were prevalent with a subpopulation of intracellular Cx43 localized to lysosomes.

    Chloroquine and methylamine, which accumulate in lysosomes by virtue of their weak base properties, inhibited hepatocytic protein degradation to the same extent as ammonia, with no additivity. Chloroquine is also a lysosomotropic agent, meaning it accumulates preferentially in the lysosomes of cells in the body. The pK a for the quinoline nitrogen of chloroquine is 8.5, meaning it is about 10% deprotonated at physiological pH as calculated by the Henderson-Hasselbalch equation. This decreases to about 0.2% at a lysosomal pH of 4.6. Dec 02, 2016 In this study, we aimed to investigate the influence of lysosomotropic agent, chloroquine, on the efficacy of obinutuzumab-mediated cytotoxicity. As PCD is dependent on lysosomal destabilization, we hypothesized that combination of obinutuzumab with lysosome-destabilizing agent would result in increased cell death.

    Interestingly, lactacystin inhibition of proteosomal degradation in MDA-MB-231 cells resulted in a marked increase in phosphorylated Cx43 at the expense of non-phosphorylated Cx43, and this change corresponded with an increase in “oversized” gap junction plaques. In both cell types, Western blots revealed a notable increase in total cellular Cx43 in response to lysosome inhibitors.

    Treatment of cells with the macrolide antibiotic bafilomycin A1, an inhibitor of vacuolar V-ATPase, or with the lysosomotropic agent chloroquine, has been shown to pharmacologically inhibit autophagy as evidenced by an accumulation of autophagosomes, which in turn causes Bax-dependent apoptosis. However, bafilomycin A1 has also been reported to inhibit chloroquine-induced apoptosis. Sep 15, 2019 Lysosomal inhibitors are used for studying autophagy in physiological and pathological processes Mizushima et al. 2010, and chloroquine derivative hydroxychloroquine is the only clinically approved autophagy inhibitor currently in clinical trials as an adjunct to conventional chemotherapy Chude and Amaravadi, 2017. Altogether, our findings demonstrate that IMB-6G is a novel autophagy inhibitor, which induces autophagy-dependent apoptosis through autophagosomal-cathepsin axis in pancreatic cancer cells and.

    Hydroxychloroquine Uses, Dosage & Side Effects - Hydroxychloroquine is a quinoline medicine used to treat or prevent malaria, a disease caused by parasites that enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia. This medicine is not effective against all strains of malaria.
