Role of Oxidative Stress in Modulating Unfolded Protein Response Activity in Chronic Myeloid Leukemia Cell Line
Background: Recently, it has been revealed that tyrosine kinase inhibitors (TKIs) act through inducing both oxidative and endoplasmic reticulum (ER) stress in chronic myeloid leukemia cells. However, ER stress signaling triggers both apoptotic and survival processes within cells. Nevertheless, mechanisms by which TKIs avoid the pro-survival effects are not clear. The aim of this study was to ev...
متن کاملThe Effect of Resistance Training and Berberine Chloride on the Apoptosis-Related Unfolded Protein Response Signaling Pathway in the Hippocampus of Diazinon-Poisoned Rats
Introduction: Diazinon is one of the most widely-used organophosphate pesticides in the world. This toxin enters the body in various ways and induces oxidative stress in various tissues. It has been proved that activation of unfolded protein response (UPR) under oxidative stress is a steady mechanism for maintaining cell function and survival. Therefore, the present study aimed to review the ef...
متن کاملSpotlight on Rett Syndrome : Review The Odyssey of MeCP 2 and Parental Imprinting
DNA methylation in mammals has long been implicated in the epigenetic mechanism of parental imprinting, in which selective expression of one allele of specific genes is based on parental origin. Methyl CpG binding protein 2 (MeCP2) selectively binds to methylated DNA and mutations in the MECP2 cause the autism‐spectrum neurodevelop‐ mental disorder Rett syndrome. This review outlines the emergi...
متن کاملThe Unfolding Tale of the Unfolded Protein Response
Surface and secreted proteins are synthesized in the endoplasmic reticulum where they must fold and assemble before being transported. Changes in the ER that interfere with their proper maturation initiate the unfolded protein response pathway. New studies have filled in a missing link between the yeast and mammalian pathways.
متن کاملUnfolded Protein Response and Macroautophagy in Alzheimer's, Parkinson's and Prion Diseases.
Proteostasis are integrated biological pathways within cells that control synthesis, folding, trafficking and degradation of proteins. The absence of cell division makes brain proteostasis susceptible to age-related changes and neurodegeneration. Two key processes involved in sustaining normal brain proteostasis are the unfolded protein response and autophagy. Alzheimer's disease (AD), Parkinso...
