We then investigated autophagic flux in vivo by injecting WT mice with chloroquine, an inhibitor of autophagic flux LC3 staining (red) and DNA (blue), images taken at 100× magnification and exported to Adobe Photoshop for processing. LC3B (D11) XP ® Rabbit mAb detects endogenous levels of total LC3B protein. J. Autophagy is the bulk degradation of cytoplasmic components - literally, self-digestion of the cell. After its chloroquine lc3 translation, the unprocessed form of LC3 (pro-LC3) is proteolytically cleaved by Atg4 protease, resulting in the formation of LC3-I form with a carboxyterminal exposed glycine The LC3-II/I ratio reflects the conversion of the protein from the cytosolic form to the autophagosome associated form upon autophagy activation and was also calculated and showed significant increases for both bafilomycin and chloroquine treatments, although chloroquine was statistically further increased, albeit modestly, from bafilomycin. Besides, lysosomal inhibitor chloroquine did not induce additional increase of LC3-II and P62 abundance after I/R but it reversed the effects of BMPoC in those parameters in cardiomyocytes. May 24, 2016 · (a) Starvation enhances colocalization of endogenous TRIM31 and LC3 in the intestinal epithelial cell line, Caco-2.
