Next, using transcriptomics and proteomics, we report a comprehensive stress response elicited by two types of targeting signal-fused stressor proteins. Webb22 nov. 2024 · Folding stressors stabilized proteins via aggregation rather than overburdening the proteasome, as occurred under proteolytic stress. Still, the UPS productively adapted to both stressors using separate mechanisms: proteolytic stressors caused Rpn4 stabilization while folding stressors increased RPN4 transcription.

WebbFör 1 dag sedan · Surprisingly, ATF4 translation remains inhibited even after acute proteotoxic and amino acid starvation stressors, resulting in a highly diminished stress response. Furthermore, absent a response, stress exacerbates the senescence secretory phenotype and inflammatory pathways thus acting as a possible mechanistic link to … Webbproteotoxic conditions. Two ways stressors may increase levels of misfolded proteins are to (1) cause proteins to misfold or obstruct their folding (“folding stress”), or (2) impair degrada-tion rates of misfolded proteins (“proteolytic stress”; Fig. 1 A). A naive expectation is that folding and proteolytic stressors have
