Autophagy functions as a survival mechanism during cellular stress and contributes to resistance against anticancer agents. The selective antitumor and antimetastatic chelator di-2-pyridylketone 4,4-dimethyl-3-thiosemicarbazone (Dp44mT) causes lysosomal membrane permeabilization and cell death. Considering the integral role of lysosomes in autophagy

We assessed whether chronic treadmill exercise attenuated restraint stress-induced cognition impairment. Although serum corticosterone was not significantly altered by exercise, the restraint-induced increases in hippocampal malondialdehyde (MDA) and 4-hydroxynonenal (HNE) were reduced by chronic exercise. The exercise paradigm also reversed
