    Chloroquine protein degradation


    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.

    Aug 11, 2005 At the end of this clearly understandable and apparently difficult deliberation, he left us with a vague explanation linking protein degradation to protein synthesis, a process that was known to. 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. These compounds therefore seem to block the lysosomal pathway of protein degradation selectively and completely. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes 2, 3, such as the signaling of intracellular TLRs. Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4.

    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.

    In biomedicinal science, chloroquine is used for in vitro experiments to inhibit lysosomal degradation of protein products. References edit ^ a b c d e f g h i j k l "Aralen Phosphate". However, the incidence of gap junction plaques did increase by 61–88% when lysosomal and proteasomal degradation were simultaneously inhibited Fig. 6, D, F, and H, double arrows, and I, suggesting that it was proteasomal, but not lysosomal, inhibition that was responsible for the increase in number of gap junction plaques in MDA-MB-231vCx43. At the end of this clearly understandable and apparently difficult deliberation, he left us with a vague explanation linking protein degradation to protein synthesis, a process that was known to.

Finally, I have seen another rheumy for a second opionion, and have received the diagnosis of Undifferentiated Connective Tissue Disease UCTD that could develop in to Lupus. My blood work is not yet providing solid evidence for a Lupus diagnosis to be made.
