Genetic approaches using these disease models demonstrate that the chaperome plays a crucial role in protecting cells from proteotoxicity. PubMed:27491084

Although HSP70 was not identified as a modifier of α -synuclein in the screen studies we selected, directed overexpression of HSP70 has been shown to reduce α -synuclein-related proteotoxicity, supporting a central role for HSP70 in diseases of protein misfolding (Auluck et al., 2002).

Multiple studies in model systems demonstrate that overexpression of HSP70 can reduce toxicity and protein aggregation. PubMed:27491084

In addition to co-chaperones, overexpression of the human sHSP (HSPB7), a Caenorhabditis elegans HSP100 homolog (tor-2), and the yeast HSP60 subunit (CCT-1) and HSP90 homolog (HSP82) reduced toxicity and aggregation (Cao et al., 2005; Tam et al., 2006; Liang et al., 2008; Vos et al., 2010).

Likewise, overexpression of the yeast TPR-domain-containing co- chaperone STI1 suppresses toxicity in a yeast model expressing the expanded huntingtin fragment (Wolfe et al., 2013). PubMed:27491084

The co- chaperone HSP40 (dHdj-1 and SIS1) and the nucleotide exchange factor SSE1 that specifically modulate HSP70 activity were also shown to suppress toxicity and aggregation in yeast and fly disease models (Chan et al., 2000; Krobitsch and Lindquist, 2000; Sadlish et al., 2008). PubMed:27491084

For this purpose, we focused on the well-characterized DK280 mutation (10–13), which specifically leads to aggregation-mediated toxicity. PubMed:22611162
