Heat-shock protein synthesis by human polymorphonuclear cells
Mature human neutrophils from peripheral blood are known to be capable of limited protein biosynthetic activity. We now show that these cells are inducible for heat-shock protein synthesis when placed in short-term culture. Synthesis of hsp70 and hsp85 as well as the response to various temperatures and the time course of induction were typical for mammalian cell systems. This heat-shock respon...
متن کاملRegulation of heat shock protein 70 synthesis by heat shock in the preimplantation murine embryo.
Induced thermotolerance in murine embryos occurs at the 8-cell stage when embryos are maintained in vitro but not until the blastocyst stage if development proceeds in vivo. Present results indicate that ability of embryos to undergo induced thermotolerance is not limited by heat shock protein 70 (HSP70) synthesis. Exposure of 8-cell embryos to 40 degrees C enhanced synthesis of 2 constitutive ...
متن کاملInduction of apoptosis by quercetin: involvement of heat shock protein.
Quercetin, a widely distributed bioflavonoid, inhibits the growth of tumor cells. The present study was designed to investigate the possible involvement of apoptosis and heat shock protein in the antitumor activity of quercetin. Treatment with quercetin of K562, Molt-4, Raji, and MCAS tumor cell lines resulted in morphological changes, including propidium iodide-stained condensed nuclei (intact...
متن کاملErythrophagocytosis induces heat shock protein synthesis by human monocytes-macrophages.
Exposure of cells to elevated temperatures and other environmental stresses results in the expression of specific genes encoding the so-called heat shock proteins (HSPs). Since exogenous H2O2 induces in human monocytes the synthesis of HSPs, and previous induction of HSPs protects these cells from oxidative injury, we investigated whether HSP synthesis was also induced during generation of reac...
متن کاملheat-shock protein synthesis study by micro-chip
keeping constant all agronomic factors except temperature is a way to follow heat shock proteins (hsps) expression. three different sunflower hybrids derived from the cross between an inbred line, cms ha 89, and three different restorer inbred lines, with resistance, susceptible, and normal reactions to drought, were produced. in order to investigate the impact of temperature on protein accumul...
