Higher plants produce both high mo1 wt (in the range of 70,000-110,000) and LMW (in the range of 15,000-30,000) HSPs in response to heat-stress conditions. During periods of heat stress, plant cells produce an abundance of LMW HSPs that are encoded by gene families (Vierling, 1991). The physiological function of these proteins remains obscure, but the evolutionary conservation of this response ...

Background Heat shock proteins (HSPs) have been reported to be overexpressed in a wide range of human tumors. It has been shown that HSPs act as an oncogenic regulator and are involved in tumorigenesis. The clinical and prognostic significance of HSPs in gastrointestinal cancers (GICs) remains controversial. The aim of this study was to conduct a meta-analysis to assess the prognostic value of ...

Healthcare professionals, because they recommend vaccines to their patients, answer questions, and vaccinate them, are the cornerstone of vaccination in France. They can nonetheless be affected by vaccine hesitancy (VH). Aims. We sought study opinions, practices, perceptions French hospital staff physicians (HSPs) toward prevalence correlates VH among them. Methods. conducted a cross-sectional ...

Immunization with heat shock proteins (HSPs) induces Ag-specific CTL responses. The specificity of the immune response is based on peptides associated with HSPs. To investigate how exogenous HSP/peptide complexes gain access to the MHC class I-restricted Ag presentation pathway, we incubated the monocytic cell line P388D1 and the dendritic cell line D2SC/1 with gold-labeled HSPs gp96 and HSC70....

Heat shock proteins (HSPs) are a large family of proteins highly conserved throughout evolution because of their unique cytoprotective properties. Besides assisting protein refolding and regulating proteostasis under stressful conditions, HSPs also play an important role in protecting cells from oxidative stress, inflammation, and apoptosis. Therefore, HSPs are crucial in counteracting the dele...

Heat-shock proteins (Hsps) are molecular chaperones that are ubiquitously expressed but are also induced in cells exposed to stressful stimuli. Hsps have been implicated in the induction and propagation of several diseases. This paper focuses on regulatory factors that control the transcription of the genes encoding Hsps. We also highlight how distinct transcription factors are able to interact...

Cells from virtually all organisms respond to a variety of stresses by the rapid synthesis of a highly conserved set of polypeptides termed heat shock proteins (HSPs). The precise functions of HSPs are unknown, but there is considerable evidence that these stress proteins are essential for survival at both normal and elevated temperatures. HSPs also appear to play a critical role in the develop...

Cormels of Gladiolus X gandavensis Van Houtte respond to heat shock by an induced synthesis of heat shock proteins. Synthesis of some of the non-heat shock proteins is concomitantly reduced. The ability of dormant cormels to synthesize heat shock proteins (hsps) and to repress the synthesis of non-hsps is greater than that of nondormant ones. A hsp of apparent molecular weight 68 kilodaltons is...
