The trade-off involves accepting higher variability and reduced regulatory oversight in exchange for accessibility
90-kDa ribosomal S6 kinase 1 is inhibited by S-glutathionylation of its active-site cysteine residue during oxidative stress
This process, along with GCL inhibition and the formation of mixed disulfides between GSH and protein sulfhydryl, concurred to a steady-state decrement of free GSH concentration and, consequently, to an intracellular redox state shift toward more oxidizing conditions, which could be required for avoiding fast reduction of oxidized cysteines allowing the upstream ROS-induced autophagic stimulus to be propagated
Most findings so far come from animal studies and preclinical research, but the potential implications are significant
It's unclear exactly why they died, but that delayed the field of gene therapy by at least a decade
Many patients wonder whether they can discontinue GLP-1 medications like semaglutide after reaching their weight loss goals
