    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.

    The conjugated form of LC3 is called LC3-II and regarded as specific marker of autophagy. Meanwhile, recent studies indicate the p62 protein function as an adaptor molecule involved in activating autophagy that interacts with polyubiquitinated protein aggregates and targets them to autophagosomes 18. 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. The LC3 Antibody Kit for Autophagy includes a rabbit polyclonal antibody against LC3B that has been validated for use in fluorescence microscopy and high content imaging and analysis. Chloroquine diphosphate is also included - following treatment with this compound, normal autophagic flux is disrupted and autophagosomes accumulate as a result of the disruption in normal autophagic flux.

    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.

  5. 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.

    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. Since autophagy is a constitutive cellular degradation process, the use of an autophagy detection reagent will prevent the lysosomal degradation of LC3, allowing its quantification by flow cytometry. The monomeric GFP used in our fusion protein to LC3 is attached on the 5' end N-terminal fusion, protecting the GFP from Atg4 cleavage, thus, allowing its visualization within the autophagosomes. Chloroquine also enhances the anti-neoplastic effects of the histone deacetylase inhibitor vorinostat SAHA 5. Chloroquine treatment of cells leads to accumulation of light chain 3-II LC3-II 1-3. This autophagy marker resides within autophagosomal membranes during the autophagic process and is degraded upon fusion with lysosomes.

    Hydroxychloroquine DermNet NZ Haemolysis in patients with glucose-6-phosphate dehydrogenase G6PD deficiency, aplastic anaemia, and leukopenia has been reported. The most extensive study to date evaluating G6PD deficiency with concurrent use of hydroxychloroquine reported no episodes of haemolysis in over 700 months of exposure among the 11 studied patients with G6PD.
