Accumulation of heat shock protein 72 (hsp 72) in postimplantation rat embryos after exposure to various periods of hyperthermia (40 degrees -43 degrees C) in vitro: evidence that heat shock protein 72 is a biomarker of heat-induced embryotoxicity.

A monoclonal antibody to the 72 kDa heat shock protein and Western blot analysis were used to determine the induction, accumulation and turnover of hsp 72 after day 10 rat embryos were exposed to elevated temperatures (40 degrees-43 degrees C) for various lengths of time (2.5 minutes to 18 hours). Embryos exposed to temperatures that exceed the normal culture temperature (37 degrees C) by 4 degrees C or more for as little as 2.5 minutes (43 degrees C) or 15 minutes (41, 42 degrees C) synthesized and accumulated detectable amounts of heat-inducible hsp 72. Hsp 72 could not be detected by Western blot analysis of proteins from embryos cultured at 40 degrees C or below. Once induced, hsp 72 can be detected in embryos for 24-48 hours after they are removed from the hyperthermic conditions and returned to normothermic conditions. Our results also indicate that hsp 72 is induced by all hyperthermic exposures that induce alterations in rat embryo growth and development; therefore, hsp 72 is a potential biomarker for heat-induced embryotoxicity.[1]
