Heat and drought are among the leading environmental stresses which have a major impact on plant development. In our research, identification characterization of differentially expressed genes (DEGs) regulating response wheat to drought, heat combined stress was carried out. We analyzed data from Gene Expression Omnibus database (GEO) microarrays containing 24 samples wheat, were categorized by...
Appropriate responses of organisms to heat stress are essential for their survival. In eukaryotes, adaptation to high temperatures is mediated by heat shock transcription factors (HSFs). HSFs regulate the expression of heat shock proteins, which function as molecular chaperones assisting in protein folding and stability. In many model organisms a great deal is known about the products of hsf ge...
PURPOSE To examine the distribution of human heat shock proteins (HSPs) HSP90, inducible HSP70 (iHSP70), constitutive and inducible HSP70 (cHSP70), HSP65, and human HSP27 in conjunctival biopsy specimens of ocular cicatricial pemphigoid (OCP), atopic keratoconjunctivitis, and healthy persons with cataract. METHODS Using an immunoperoxidase technique, conjunctival biopsy specimens from ten pat...
A 2.7 kb DNA fragment encoding the 60 kDa common antigen (CA) and a 13 kDa protein of Legionella micdadei was sequenced. Two open reading frames of 57,677 and 10,456 Da were identified, corresponding to the heat shock proteins GroEL and GroES, respectively. Typical -35, -10, and Shine-Dalgarno heat shock expression signals were identified upstream of the L. micdadei groEL gene. Further upstream...
The transcription of three specific genes has been examined in heat-shocked drosophila cells by hybridizing pulse-labeled nuclear RNA with cloned DNA sequences. Actin gene transcription is rapidly and profoundly suppressed upon heat shock but returns to near- normal levels after cells are placed back at their normal culture temperature (23 degrees C). Conversely, the transcription of genes codi...
Objective(s):Hyperglycemia worsens the neuronal death induced by cerebral ischemia. Previous studies demonstrated that diabetic hyperglycemia suppressed the expression of heat shock protein 70 and 60 (HSP70 and 60) in the liver. IgG antibody titres against heat shock protein 27 (anti HSP27) were measured to determine whether hyperglycemia exacerbates ischemic brain damage by suppressing the exp...
Recombinant adeno-associated virus 2 (AAV) vectors transduction efficiency varies greatly in different cell types. We have described that a cellular protein, FKBP52, in its phosphorylated form interacts with the D-sequence in the viral inverted terminal repeat, inhibits viral second strand DNA synthesis, and limits transgene expression. Here we investigated the role of cellular heat-shock prote...
Previously, we proposed a dual control mechanism for the regulation of the heat shock response in mammalian cells: a positive control mediated by the heat shock transcription factor HSF1 and a negative control mediated by the constitutive heat shock element-binding factor (CHBF). To study the physiological role of CHBF in the regulation of heat shock response, we purified CHBF to apparent homog...
The promoter region of the Arabidopsis AtHsp90-1 gene is congested with heat shock elements and stress response elements, as well as with other potential transcriptional binding sites (activating protein 1, CCAAT/enhancer-binding protein element, and metal regulatory element). To determine how the expression of this bona fide AtHsp90-1 gene is regulated, a comprehensive quantitative and qualita...
