As such, it is feasible that any reduction in the protein degradation capacity of a cell could contribute to proteostasis collapse and promote aging. PubMed:25784053
An in silico screen based on the structure of 10-NCP, an Akt inhibitor that potently induces autophagy (144), identified the molecules FPZ and MTM as potent activators of autophagic flux and clearance of TDP-43 in mammalian cells (145). PubMed:25784053
Additionally, an investigation of chaperone and cochaperone gene expression in young (36±4 years of age) and aged (73 ±4 years of age) human brain tissue revealed that of 332 genes examined, 101 are significantly repressed with age, including HSP70, HSP40, HSP90, and TRiC genes (113). Furthermore, 62 chaperone genes, including several small HSPs, were found to be significantly induced, likely as a result of the cellular response to accumulating protein damage with age (113).

Disruption of the ATF6 arm of the UPR(ER) is reported to occur in mouse models of HD and a VAPB cell model of ALS, suggesting that differential changes in UPR arms may be a feature of disease progression (102, 103). PubMed:25784053
One strategy is to directly activate HSF1, thereby increasing the expression of multiple molecular chaperones simultaneously. This approach has been traditionally achieved by inhibition of HSP90 with compounds that bind the N-terminal ATP-binding pocket, such as radicicol, geldanamycin, or 17-AAG (64, 132–134).
