Downhill running and exercise in hot environments increase leukocyte Hsp72 (HSPA1A) and Hsp90α (HSPC1) gene transcripts.
Stressors within humans and other species activate Hsp72 and Hsp90α mRNA transcription, although it is unclear which environmental temperature or treadmill gradient induces the largest increase. To determine the optimal stressor for priming the Hsp system, physically active but not heat-acclimated participants (19.8 ± 1.9 and 20.9 ± 3.6 yr) exercised at lactate threshold in either temperate (20...
متن کاملHeterooligomeric complexes formed by human small heat shock proteins HspB1 (Hsp27) and HspB6 (Hsp20).
Formation of heterooligomeric complexes of human small heat shock proteins (sHsp) HspB6 (Hsp20) and HspB1 (Hsp27) was analyzed by means of native gel electrophoresis, analytical ultracentrifugation, chemical cross-linking and size-exclusion chromatography. HspB6 and HspB1 form at least two different complexes with apparent molecular masses 100-150 and 250-300 kDa, and formation of heterooligome...
متن کاملRegulation of stress-induced intracellular sorting and chaperone function of Hsp27 (HspB1) in mammalian cells.
In vitro, small Hsps (heat-shock proteins) have been shown to have chaperone function capable of keeping unfolded proteins in a form competent for Hsp70-dependent refolding. However, this has never been confirmed in living mammalian cells. In the present study, we show that Hsp27 (HspB1) translocates into the nucleus upon heat shock, where it forms granules that co-localize with IGCs (interchro...

15 صفحه اولVitamin C, A and E supplementation decreases the expression of HSPA1A and HSPB1 genes in the leukocytes of young polish figure skaters during a 10-day training camp
BACKGROUND Overexpression of HSPA1A and HSPB1 has been shown to indicate stress and the degradation of damaged proteins. Therefore, the expression of these genes is often evaluated during exercise. Vitamin supplementation in young athletes may affect the expression of these genes, and help to maintain health and improve the effects of training. METHODS Fourteen top junior female athletes (age...
