Synergistic Lysosomal Impairment and ER Stress Activation for Boosted Autophagy Dysfunction Based on Te Double‐Headed Nano‐Bullets (Small 27/2022)
نویسندگان
چکیده
Autophagy To overcome the autophagy compromised mechanism of protective cellular processes by “eating” damaged organelles or potentially toxic materials in tumor cells, Nan Li and co-workers show how tellurium double-headed nanobullets (TeDNBs)-HO is utilized to induce dysfunction. On one hand, TeDNBs-mediated endoplasmic reticulum stress could excessively autophagy; thus, resulting autophagosome accumulation. other omeprazole would deacidify impair lysosomes, therefore blocking degradation. More details can be found article number 2201585.

Silica nanoparticles induce autophagy dysfunction via lysosomal impairment and inhibition of autophagosome degradation in hepatocytes
Autophagy dysfunction is considered as a potential toxic mechanism of nanomaterials. Silica nanoparticles (SiNPs) can induce autophagy, but the specific mechanism involved remains unclear. Therefore, the aim of this study was to confirm the effects of SiNPs on autophagy dysfunction and explore the possible underlying mechanism. In this article, we reported that cell-internalized SiNPs exhibited...
متن کاملER stress, autophagy, and RNA viruses
Endoplasmic reticulum (ER) stress is a general term for representing the pathway by which various stimuli affect ER functions. ER stress induces the evolutionarily conserved signaling pathways, called the unfolded protein response (UPR), which compromises the stimulus and then determines whether the cell survives or dies. In recent years, ongoing research has suggested that these pathways may b...
متن کاملER Stress and Autophagy Dysfunction Contribute to Fatty Liver in Diabetic Mice
Diabetes mellitus and nonalcoholic fatty liver disease (NAFLD) are often identified in patients simultaneously. Recent evidence suggests that endoplasmic reticulum (ER) stress and autophagy dysfunction play an important role in hepatocytes injury and hepatic lipid metabolism, however the mechanistic interaction between diabetes and NAFLD is largely unknown. In this study, we used a diabetic mou...
متن کاملLinking ER Stress to Autophagy: Potential Implications for Cancer Therapy
Different physiological and pathological conditions can perturb protein folding in the endoplasmic reticulum, leading to a condition known as ER stress. ER stress activates a complex intracellular signal transduction pathway, called unfolded protein response (UPR). The UPR is tailored essentially to reestablish ER homeostasis also through adaptive mechanisms involving the stimulation of autopha...
متن کاملMitochondrial dysfunction and oxidative stress mediate the physiological impairment induced by the disruption of autophagy
Impaired or deficient autophagy is believed to cause or contribute to aging, as well as a number of age-related pathologies. The exact mechanism through which alterations in autophagy induce these various pathologies is not well understood. Here we describe the creation of two in vivo mouse models that allow for the characterization of the alteration in mitochondrial function and the contributi...
