✦ Synopsis

Abstract

Several embryonic stages (nuclear multiplication stage up to blastoderm) were incubated at 37°C. The 84,000 dalton heat‐shock protein was always present in the heat‐shocked embryos at all these stages. This protein was also found in nonheat‐shocked controls. Different amounts of two other heat‐shock proteins, the 70,000 and 68,000 daltons, were synthesized depending upon the embryonic stage. A massive synthesis of these two later proteins was observed in embryos which were able to recover from the heat‐shock.

We employed whole-mount in situ hybridization and immunohistochemistry to study the spatial pattern of hsp30 gene expression in normal and heatshocked embryos during Xenopus laevis development. Our findings revealed that hsp30 mRNA accumulation was present constitutively only in the cement gland of

The influence of cell hydration and taurine on the heat shock response was studied in primary rat hepatocytes. Heat-induced accumulation of inducible heat shock protein 70 (HSP70) mRNA and protein was increased under hypoosmotic conditions. In contrast, hyper-osmotic exposure blocked the HSP70 respo
