The role of heat-shock proteins in thermotolerance

Yeast metabolic and signaling genes are required for heat-shock survival and have little overlap with the heat-induced genes

“…The phenomenon of acquired thermotolerance, in which cells are protected from a lethal heat stress via pretreatment by sublethal heat stress, has been well characterized (11,25). We sought to identify Fig.…”

“…Both thermotolerance and acquired thermotolerance have been studied in detail, with a general focus on the roles of transcripts or proteins that increase in abundance as part of the heat-shock response (1,(11)(12)(13)(14). Classically, this set of genes/proteins includes the molecular chaperones, which often are induced in response to stress (14).…”

Resistance to heat and cold stress in Drosophila melanogaster: intra and inter population variation in relation to climate

“…The molecular basis of the regulation of the heat shock response (Maresca and Lindquist, 1991;Morimoto et al, 1990Morimoto et al, , 1994, which occurs across all kingdoms of life (Landry et al, 1982;Vierling, 1991;Parsell and Lindquist, 1994), provides a link between conditioning treatments that induce heat shock protein production and those increasing survival under thermal stress or other stress types (Landry et al, 1982;Lindquist, 1986;Brown, 1991 (Cavicchi et al, 1989(Cavicchi et al, , 1995 (Stalker and Carson, 1947;Prevosti, 1955;Misra and Reeve, 1964;David et al, 1977;David and Capy, 1988;Capy et al, 1993;Imasheva et al, 1994). A genetic and phenotypic relationship between body size and temperature also has been shown in the laboratory (Anderson, 1973;Cavicchi et al, 1985Cavicchi et al, , 1989, where adult body size negatively correlated with temperature (Starmer and Wolf, 1989;Thomas, 1993), except at temperatures approaching the limit for development .…”

Temperature Affects Adhesion of the Acorn Barnacle (Balanus amphitrite)

“…Heat-shock proteins are molecular chaperones whose synthesis is thought to be induced by environmental conditions that are detrimental to cellular protein structure (Parsell et al 1993). Barnacles experiencing different temperatures have shown to react at a cellular and molecular level which may very well extend to their production of adhesive protein and ability to adhere.…”
