Heat shock factor 1 and heat shock proteins: Critical partners in protection against acute cell injury.
OBJECTIVE: Life-threatening conditions cause severe changes in the organization and conformation of macromolecules, creating urgent requirements for protein repair to ensure survival. As molecular chaperones, heat shock proteins (HSP) that have specialized functions in protein folding are now well established to restore homeostasis in cells and organisms. Augmentation of HSP synthesis is tightl...
متن کاملHDAC Inhibitors and Heat Shock Proteins (Hsps)
Epigenetic alterations, including DNA acetylation, hypermethylation and hypomethylation, and the associated transcriptional changes of the affected genes are central to the evolution and progression of various human cancers, including pancreatic cancer. Cancer-associated epigenetic alterations are attractive therapeutic targets because such epigenetic alterations, unlike genetic changes, are po...
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 ...
متن کاملHeat shock proteins and protection against ischemic injury.
Heat shock proteins present a complex family of proteins exerting chaperone-like activities that are classified according to their molecular weight. We especially explored protective functions of inducible heat shock protein 70, the mitochondrial heat shock protein 60 and 10, and the small heat shock proteins HSP27 and alphaB-crystallin against ischemic, reoxygenation-mediated injury using tran...
متن کاملHeat shock proteins and cardiac protection.
The heat shock proteins (hsps) are expressed in normal cells but their expression is enhanced by a number of different stresses including heat and ischaemia. They play important roles in chaperoning the folding of other proteins and in protein degradation. In the heart a number of studies have shown that prior induction of the hsps by a mild stress has a protective effect against a more severe ...
