    Autophagic flux chloroquine


    Three forms of autophagy are commonly described: macroautophagy, microautophagy, and chaperone-mediated autophagy (CMA). In macroautophagy, expendable cytoplasmic constituents are targeted and isolated from the rest of the cell within a double-membraned vesicle known as an autophagosome, which, in time, fuses with an available lysosome, bringing its specialty process of waste management and disposal; and eventually the contents of the vesicle (now called an autolysosome) are degraded and recycled.

    Chloroquine or bafilomycin A1, two known inhibitors of autophagic flux, also increased the level of LC3B-II as tenovin-6 did. As expected, Torin 1 treatment induced SQSTM1/p62 degradation. Autophagy-modifying agents, such as rapamycin and chloroquine, at pharmacological doses have previously shown to alter the autophagic flux. If tenovin-6 is an inducer of the autophagic flux, the combined treatment of tenovin-6 with a saturated inhibitor like bafilomycin A1 should lead to an additive effect on LC3B expression.

    In the extreme case of starvation, the breakdown of cellular components promotes cellular survival by maintaining cellular energy levels. In disease, autophagy has been seen as an adaptive response to stress, promoting survival of the cell; but in other cases it appears to promote cell death and morbidity.

  7. Chloroquine is a lysosomotropic weak base, which in the monoprotonated form diffuses into the lysosome, where it becomes diprotonated and becomes trapped. Protonated chloroquine then changes the lysosomal pH, thereby inhibiting autophagic degradation in the lysosomes.

    Autophagic flux is a general term used to define the rate of autophagosome-mediated intracellular degradation activity in response to or associated with a particular physiological situation 10. Regulation of autophagy Autophagy or autophagocytosis from the Ancient Greek αὐτόφαγος autóphagos, meaning "self-devouring" and κύτος kýtos, meaning "hollow" is the natural, regulated mechanism of the cell that removes unnecessary or dysfunctional components. It allows the orderly degradation and recycling of cellular components. Inhibition of autophagic flux using chloroquine prevented clearance of p62 aggregates, leading to caspase-8 activation and cell death in C4-2 cells. In PC3 cells, inhibition of autophagy induction prevented p62 accumulation and hence caspase-8 activation.
