    It accumulates inside the acidic parts of the cell, including endosomes and lysosomes. This accumulation leads to inhibition of lysosomal enzymes that require an acidic p H, and prevents fusion of endosomes and lysosomes.

    Microtubule-associated protein light chain 3 LC3 is now widely used to monitor autophagy. One approach is to detect LC3 conversion LC3-I to LC3-II by immunoblot analysis because the amount of LC3-II is clearly correlated with the number of autophagosomes. 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. The antimalarial drug chloroquine CQ disrupts autophagy by inhibiting the acidification of the lysosomes that fuse with the autophagosomes, thereby preventing the degradation of metabolic stress products and inducing apoptosis. Chloroquine-mediated inhibition of autophagy has been demonstrated in melanoma.

    Moreover, Chloroquine inhibits autophagy as it raises the lysosomal p H, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation [4]. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes [2, 3], such as the signaling of intracellular TLRs.

  4. Both LC3 & GABARAP Are Essential for Autophagosome Formation. Autophagy is the main process for degrading damaged organelles and misfolded proteins. It plays a critical role in cell homeostasis, differentiation, survival during nutrient deprivation, and the growth regulation.

    Feb 05, 2010 A similar concern is also true for the measurement of LC3-II. For example, if cells are cultured with chloroquine, an agent that impairs lysosomal acidification, LC3-II accumulates even under normal nonstarved conditions because turnover of LC3-II by basal autophagy is blocked Figure 6A. Thus, one cannot distinguish between bona fide induction of autophagy e.g. by starvation and impairment of autophagolysosomal maturation simply by measuring autophagosome numbers e.g. by electron. Macroautophagy/autophagy is a conserved transport pathway where targeted structures are seques-tered by phagophores, which mature into autophagosomes, and then delivered into lysosomes for degradation. Autophagy is involved in the pathophysiology of numerous diseases and its modulation is beneficial for the outcome of numerous specific diseases. In other cases chemosensitization by chloroquine is mimicked by ATG knockdown and is thought to be due to the autophagy inhibition 24. The important point is that to know if autophagy itself is critical in a disease, one must test the requirement of multiple components of the autophagy machinery.
