The Heat Shock Response: Systems Biology of Proteotoxic Stress in Aging and Disease. Induction of the HSR leads to the rapid and robust expression of molecular chaperones and other cell-protective pathways to protect nascent chain synthesis and folding, to prevent misfolding and aggregation, and to promote recovery from stress-induced.
The heat shock response has been studied for more than 30 years, mainly in yeast and animal cells, and different models have been proposed to explain it (Anckar and Sistonen, ). The intrinsic response model, which assumes that Hsf1 directly senses increasing temperature (and potentially other stresses), relies on Hsf1 transitioning from a Author: Laura Le Breton, Matthias P Mayer.
