HSP (Heat shock proteins) are a group of proteins induced by heat shock, the most prominent members of this group are a class of functionally related proteins involved in the folding and unfolding of other proteins. HSP expression is increased when cells are exposed to elevated temperatures or other stress. This increase in expression is transcriptionally regulated. The dramatic upregulation of the heat shock proteins is a key part of the heat shock response and is induced primarily by heat shock factor (HSF). HSPs are found in virtually all living organisms, from bacteria to humans. Heat shock proteins appear to serve a significant cardiovascular role. Hsp90, Hsp84, Hsp70, Hsp27, Hsp20 and alpha B crystallin all have been reported as having roles in the cardiovasculature.

    Rosolutamide
    		Activator
    Rosolutamide (ASC-JM17), a curcumin analog, is an orally active, potent Nrf1 and Nrf2 activator. Rosolutamide activates Nrf1, Nrf2 and heat shock factor 1 (Hsf1), thereby activating the expression of proteasome subunits, antioxidant enzymes and molecular chaperones. Rosolutamide degrades the polyglutamine (polyQ) androgen receptor (AR) via the ubiquitin-proteasome pathway and improves motor function in mouse models of spinal and bulbar muscular atrophy (SBMA). Rosolutamide improves mitochondrial function and promotes autophagy, decreases mutant protein aggregates, and attenuates intracellular/mitochondrial reactive oxygen species (ROS) levels.
