Tissue-specific patterns of synthesis of heat-shock proteins and thermal tolerance of the fathead minnow (Pimephales promelas)

摘要: Qualitative and quantitative differences in the heat-shock response brain, gill, striated muscle tissues of fathead minnow (Pimephales promelas) were investigated. The maximum sublethal temperature was 34 °C. proteins (hsps) induced, their biosynthetic rates, minimum temperatures required for induction, at which each tissue synthesized hsps specific. Six induced gill (100, 90, 78, 70, 68, 60 kDa), four 70 kDa), three brain (90, 68 kDa). Minimum inducing stress muscle, 28, 31, 32 °C, respectively. Maximum hsp synthesis accumulation occurred 33 °C 34°C gill. Synthesis decreased to near pre-exposure levels fact that fewest had lowest capacity at...
