Web1 feb. 2005 · Lysosomes are sensors of reactive oxygen species (ROS) [26,27], and permeabilization of the lysosomal membrane can trigger ROS formation under … WebThe lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused. Lysosomes are part of the endomembrane system, and some vesicles that leave the Golgi are bound for the lysosome.

WebLysosomal Turnover, but Not a Cellular Level, of Endogenous LC3 is a Marker for Autophagy ABSTRACT During starvation-induced autophagy in mammals, autophagosomes form and fuse with lysosomes, leading to the degradation of the intra-autophagosomal contents by lysosomal proteases. During the formation of autophagosomes, LC3 is …

WebLysosomes are particularly sensitive to oxidative stress as intralysosomal iron can catalyze fenton chemistry and the formation of highly reactive hydroxyl radicals that damage membranes and cause lysosomal rupture (Antunes et al. 2001).
