Heat shock treatment of rat embryo fibroblasts resulted in a 60% increase in cytosolic protein kinase C activity, in contrast to phorbol ester-induced translocation to the membrane. During reversal of the cells back to the normal temperature a decrease in cytosolic PKC activity was observed and paralleled by an increase in protamine kinase activity. Cell lysates prepared from heat shock-treated cells show a marked calcium/phospholipid-dependent phosphorylation of several endogenous PKC substrate proteins, while the 28-kDa stress protein was shown to be a PKC substrate. These cells express the TYPE III-alpha isoform of PKC and, thus, the alterations induced within cells exposed to hyperthermic treatment may reflect a functional significance with regard to the regulation of this specific isoform.
