Abstract
As our group has shown, the NO-synthase inhibitor L-NNA decreased 2–3 times heat shock-induced synthesis of the heat shock protein HSP70 (FEBS Lett. 370 (1995) 159–162). It was suggested that NO is involved in such induction. In the present study, it was found that (1) injection of the NO donor dinitrosyl iron complex (DNIC) into rats results in accumulation of HSP70 in the heart; (2) heat shock is accompanied by increased generation of NO (EPR assay) and HSP70 accumulation in cultured cells; (3) DNIC induces HSP70 accumulation in cultured cells not exposed to heat shock.Keywords
