Heat shock protein 27 controls apoptosis by regulating Akt activation.
Activation of the serine-threonine kinase Akt by cytokines, chemokines, and bacterial products delays constitutive neutrophil apoptosis, resulting in a prolonged inflammatory response. We showed previously that Akt exists in a signaling complex with p38 MAPK, MAPK-activated protein kinase-2 (MAPKAPK-2), and heat shock protein-27 (Hsp27); and Hsp27 dissociates from the complex upon neutrophil ac...
متن کاملReductive stress: linking heat shock protein 27, glutathione, and cardiomyopathy?
Normal cellular functions essentially depend on a balanced redox environment. Free radicals and nonradical oxidants can shift the redox balance toward a more “oxidized” state, which is counteracted by the intracellular antioxidant defense systems. These include the enzymes superoxide dismutase and catalase, as well as the thiol-reducing systems (glutathione, glutaredoxin, and thioredoxin). Glut...
متن کاملRetinal preconditioning and the induction of heat-shock protein 27.
PURPOSE Brief periods of ischemia have been shown to protect the retina from potentially damaging periods of ischemia. This phenomenon has been termed ischemic preconditioning or ischemic tolerance. In the present study the cellular changes in levels of heat shock protein (Hsp)27, -70, and -90 mRNA and expression of Hsp in the rat retina associated with ischemic preconditioning were evaluated. ...
متن کاملThe expanding small heat-shock protein family, and structure predictions of the conserved "alpha-crystallin domain".
The ever-increasing number of proteins identified as belonging to the family of small heat-shock proteins (shsps) and alpha-crystallins enables us to reassess the phylogeny of this ubiquitous protein family. While the prokaryotic and fungal representatives are not properly resolved, most of the plant and animal shsps and related proteins are clearly grouped in distinct clades, reflecting a hist...
متن کاملHeat shock and the heat shock proteins.
As all biologists appreciate, there is constant interaction between life and the environment, and temperature plays a critical role. It establishes distribution limits, it affects rates of function as well as the survival of organisms. Notoriously sensitive to temperature is plant growth. Critical steps in plant life such as germination, flowering and breaking of dormancy can be manipulated by ...
