Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2005
Mammalian renal inner medullary cells are normally exposed to extremely high NaCl concentrations. Remarkably, under these normal conditions, the high NaCl causes DNA damage and inhibits its repair, yet the cells survive and function both in cell culture and in vivo. The interstitial NaCl concentration in parts of a normal renal medulla can be 500 mM or

Current Opinion in Structural Biology, 2007
Bacteria, irrespective of natural habitat, are exposed to constant fluctuations in their growth conditions. Consequently they have developed sophisticated responses, modulated by the re-modelling of protein complexes and by phosphorylation-dependent signal transduction systems, to adapt to and to survive a variety of insults.

Scandinavian Journal of Gastroenterology, 1999
Upper gastrointestinal endoscopy is often accompanied by tachycardia, which may lead to myocardial ischaemia. The pathogenesis for tachycardia is unknown, but the classic endocrine stress response may be of importance.Seventeen patients (median age, 60 years) undergoing diagnostic gastroscopy without sedation or supplemental oxygen therapy were ...

Brassinosteroid-Mediated Stress Responses
Journal of Plant Growth Regulation, 2003Brassinosteroids (BRs) are a group of naturally occurring plant steroidal compounds with wide-ranging biological activity that offer the unique possibility of increasing crop yields through both changing plant metabolism and protecting plants from environmental stresses.

Toxicology in Vitro, 1998
There is emerging realization that biological systems are capable of eliciting co-ordinated patterns of biochemical alterations in response to various forms of chemical and physical stress. In terms of the toxicity response, it is becoming apparent that such dynamic responses provide a link in biological homeostasis between normal cellular physiology ...

Endoplasmic reticulum stress responses
Cellular and Molecular Life Sciences, 2007In homeostasis, cellular processes are in a dynamic equilibrium. Perturbation of homeostasis causes stress. In this review I summarize how perturbation of three major functions of the endoplasmic reticulum (ER) in eukaryotic cells -- protein folding, lipid and sterol biosynthesis, and storing intracellular Ca(2+) -- causes ER stress and activates ...
