A. Thermal Stress: 1. Forewords: A large amount of studies have been carried out in which stress to cells was provided in the form of heat shock, i.e., exposing the cells to elevated temperatures (40-42°C, in some cases up to 60°C as well). It is a known fact that prokaryotes possess only a single copy of a heat shock gene. [...]
Different classes of SPs are shown in Fig. 14.4. Much is unknown about the HSPs in the range of 100-110 KD and above. Newer information is gradually accumulating in literatures about their roles in normal cellular processes. Critical insight on the functional features of this class during heat stress and thermotolerence are yet to appear. It is stated that 110 [...]
Inducing Agents: In bio-cells or tissue organs the stress-inducing agents responsible for induction of stress response and abnormal protein formation may be classified as shown in Fig. 14.4. Chemicals and bio-chemicals are by far the largest stress conditioning agents, although heat shock is the commonly used one. Micro-flora indigenous to abyssal depths of the deep oceans are believed to be [...]
