Background: Salinity is a major environmental limiting factor, which affect agricultural production. The two Manilkara seedlings (M. roxburghiana and M. zapota) with high economic importance, could not adapt well to higher soil salinity and little is known about their proteomic mechanisms. Objectives: The mechanisms responsible ...

INTRODUCTION The important protective role of small heat-shock proteins (HSPs) in regulating cellular survival and migration, counteracting protein aggregation, preventing apoptosis, and regulating inflammation in the central nervous system is now well-recognized. Yet, their role in the neuroinflammatory disorder multiple sclerosis (MS) is largely undocumented. With the exception of alpha B-cry...

The protective effects of heat shock proteins (HSPs) during myocardial ischemia are now well documented, but little is known about the mechanisms of protection and the specificity of different HSPs. Because cytoskeletal injury plays a crucial role in the pathogenesis of irreversible ischemic damage, we tested whether overexpression of specific HSPs protects the integrity of microtubules during ...

Heat-shock proteins (HSPs) act as molecular chaperones binding endogenous antigenic peptides and transporting them to major histocompatibility complexes. HSPs chaperone a broad repertoire of endogenous peptides including tumor antigens. For the immunotherapy of tumors, a strategy using HSPs may be more advantageous than other procedures because the identification of each tumor-specific antigen ...

Many DNA base substitution models have been proposed to describe the evolution of short DNA sequences. Most of these models are special reversible time-continuous Markov chains on the DNA bases. A general reversible model for long genomic DNA sequences, which includes the previous models as special cases, is described in this paper. To estimate the model parameters from pairwise alignments, two...

Cells that have been pre-exposed to thermal stress can acquire a transient resistance against the killing effect of a subsequent thermal stress. The cause for this phenomenon, called thermotolerance, seems to be an enhanced resistance of proteins against thermal denaturation and aggregation. This resistance can be expressed as an attenuation of damage formation (less initial damage) or as a bet...

Adult T cell leukemia is a fatal malignant transformation caused by the human T-cell lymphoptropic virus type I (HTLV-I). HTLV-I is only associated with the development of this disease in a small percentage of infected individuals. Using two rabbit transformed T-cell lines; RH/K30 (asymptomatic) and RH/K34 (leukemogenic), we have investigated the expression of heat shock proteins (HSP) 90 and 7...

Parasitoid wasps inject their eggs into host along with virulent factors to manipulate hosts physiology and immune system. Heat shock proteins (HSPs) are as molecular chaperones and stress proteins induced by heat, cold, anoxia and parasitism. There was no report about the roles of HSP in insect eggs against egg parasitoids. Here, we studied the expression profiles of several HSPs in silkworm e...

Heat shock proteins (HSPs) have been known for decades for their ability to protect cells under stressful conditions. In the 1980s a new role was ascribed for several HSPs given their ability to elicit specific immune responses in the setting of cancer and infectious disease. These immune responses have primarily been harnessed for the immunotherapy of cancer in the clinical setting. However, b...

Ambient temperature is one of the most important environmental factors affecting physiological mechanisms and biochemical reactions of living organisms. Thus the effect of ambient temperature on HSPs and IGF-I gene expression levels in the liver and muscle tissues of Sparus aurata were investigated in this research. The levels of HSPs, and IGF-I gene expression of the liver and muscle of Sparus...
