Degradation of the endoplasmic reticulum by autophagy during endoplasmic reticulum stress in Arabidopsis.
In this article, we show that the endoplasmic reticulum (ER) in Arabidopsis thaliana undergoes morphological changes in structure during ER stress that can be attributed to autophagy. ER stress agents trigger autophagy as demonstrated by increased production of autophagosomes. In response to ER stress, a soluble ER marker localizes to autophagosomes and accumulates in the vacuole upon inhibitio...
متن کاملAutophagy is activated for cell survival after endoplasmic reticulum stress.
Eukaryotic cells deal with accumulation of unfolded proteins in the endoplasmic reticulum (ER) by the unfolded protein response, involving the induction of molecular chaperones, translational attenuation, and ER-associated degradation, to prevent cell death. Here, we found that the autophagy system is activated as a novel signaling pathway in response to ER stress. Treatment of SK-N-SH neurobla...
متن کاملStimulation of Autophagy Improves Endoplasmic Reticulum Stress–Induced Diabetes
Accumulation of misfolded proinsulin in the β-cell leads to dysfunction induced by endoplasmic reticulum (ER) stress, with diabetes as a consequence. Autophagy helps cellular adaptation to stress via clearance of misfolded proteins and damaged organelles. We studied the effects of proinsulin misfolding on autophagy and the impact of stimulating autophagy on diabetes progression in Akita mice, w...
متن کاملEndoplasmic reticulum stress induces autophagy in renal proximal tubular cells.
BACKGROUND Autophagy, an intracellular self-degradation system conserved throughout eukaryotes, plays an important role in a variety of biological processes, including cell death, development, cancer, defence against infection and neurodegeneration. However, little information about autophagy in renal tubular cells is available. We investigated the relationship of autophagy with endoplasmic ret...
متن کاملEndoplasmic reticulum-Golgi intermediate compartment protein 3 knockdown suppresses lung cancer through endoplasmic reticulum stress-induced autophagy
Trafficking from the endoplasmic reticulum (ER) to the Golgi apparatus is elevated in cancer cells. Therefore, proteins of the ER-Golgi intermediate compartment (ERGIC) attract significant attention as targets for cancer treatment. Enhanced cancer cell growth and epithelial-mesenchymal transition by ERGICs correlates with poor-prognosis of lung cancer. This prompted us to assess whether knockdo...
