“…This response has been studied in many cellular systems such as bacteria, yeast, insects (Drosophila melanogaster) (Michaud, Marin, & Tanguay, 1997), worms (Caenorhabditis elegans) (Rose & Rankin, 2001), and mammals (Christians, Yan, & Benjamin, 2002;Li, Menoret, & Srivastava, 2002;Srivastava, 2002). The heat-shock proteins are important for protection against environmental stress, and they produce tolerance against high temperature, high salt, and heavy metals (VanBogelen, Acton, & Neidhardt, 1987b;Inbar & Ron, 1993;. Heat-shock proteins also play critical roles in protective systems such as the human immune system (Christians, Yan, & Benjamin, 2002;Li, Menoret, & Srivastava, 2002).…”

In recent years, it has become clear that, in addition to the regulation of the expression of specific genes, there are global regulatory systems that control the simultaneous expression of a large number of genes in response to a variety of environmental stresses. The first of these global control systems, and of substantial importance, is the heat-shock response. The heat-shock response is characterized by the induction of a large set of proteins (heat-shock proteins-HSPs) upon shifts to higher temperature and upon exposure to conditions in which proteins are denatured (i.e., alcohols, heavy metals). The heat-shock response is universal and many of the heat-shock proteins are highly conserved among species. In bacteria, the heat-shock response has been studied extensively in several Gram-positive bacteria (Bacillus subtilis) and in the Gram-negative bacteria (i.e., Escherichia coli, Agrobacterium tumefaciens). The first recognition of the molecular abundance of the bacterial heat-shock proteins took place with the introduction of high-resolution two-dimensional polyacrylamide gels (2D gels) to analyze complex mixtures of cellular proteins. Two-dimensional gels, followed by mass spectrometry, were used to define the heat-shock stimulons in several bacteria, and to study the regulatory elements that control the heat-shock response. Here, we review the heat-shock response and its regulation in bacteria. The review will emphasize the use of proteome analysis in the study of this response, and will point out those open questions that can be investigated with proteomics, including mass spectrometry techniques.

“…Treatment at sublethal temperature with bacteria also induces broad protection against damage caused by ultraviolet irradiation, oxidation and high osmolarity (10,14). Although pretreatment with sublethal cadmium concentration or low salt concentration resulted in cadmium or low salt tolerance respectively, these pretreatments were less effective than heat shock or nutrient starvation in inducing thermotolerance (5,17). These results suggest that stress agents such as heavy metals or salts induce factors that are mainly essential for specific protection, while treatment at elevated ternperature and starvation induce broad protection.…”
