    Alternatively, we suggest using this opportunity to take a little break from work and read some of the interesting articles below. The present study was designed to determine the specific roles played by lysosomes and proteasomes in the degradation of Cx43 in both gap junctional intercellular communication-deficient MDA-MB-231 and -competent BICR-M1R cells.

    Both chloroquine and MG132 increased mTOR and p‐mTOR protein levels in +/+ osteoclasts, suggesting that mTOR undergoes both lysosomal and proteasomal degradation. Treatment with cycloheximide, an inhibitor of new protein synthesis, confirmed that mTOR is constitutively expressed and degraded. The amount of autophagosomes in the cytosol can be increased by two different mechanisms increased autophagosome synthesis by upstream processes and blockade of lysosomal degradation at a later. 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. References. 1.

    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. 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.

  6. Autophagy is a homeostatic cellular recycling system that is responsible for degrading damaged or unnecessary cellular organelles and proteins. Cancer cells are thought to use autophagy as a source of energy in the unfavorable metastatic environment, and a number of clinical trials are now revealing the promising role of chloroquine, an autophagy inhibitor, as a novel antitumor drug. On the.

    However, little is known about the degradation mechanism of CD81. Here we found that CD81 on the plasma membrane is degraded by the lysosome pathway via endocytosis. The expression levels of CD81 in HEK293T cells treated with a proteasome inhibitor lactacystin and lysosome inhibitors chloroquine and bafilomycin A1 were analyzed by flow. Similarly, Cx43-P 0 was more abundant than Cx43-P in the cells treated with lysosomal inhibitors chloroquine, leupeptin, or ammonia chloride; however, inhibition of lysosomes caused a significant increase in total cellular Cx43 by 69–75% Fig. 5, B and C confirming the critical role of lysosomes in Cx43 degradation in MDA-MB-231vCx43 cells. By inhibiting lysosome function, chloroquine synergistically activated glucocorticoid signaling. Lysosomal inhibition by either bafilomycin A1 an inhibitor of the vacuolar adenosine triphosphatase or knockdown of transcription factor EB TFEB, a master activator of lysosomal biogenesis mimicked the effects of chloroquine.
