HSP72 induction of systemic organs of rats after severe burn injury

HSP72 induction of systemic organs of rats after severe burn injury In order to understand the stress response of systemic organs to severe burn injury, the induction of 72-kD heat shock protein (HSP72) in various organs (brain, hypophysis, lung, heart, liver, pancreas, spleen, kidney, adrenal gland, and skeletal muscle) was investigated in rats with severe burns. A full-thickness burn was induced on the rats' skin by immersing the rats in hot water (90° C) for 3 s. At 0, 24, and 48 h after the burn injury, the HSP72 expression of various organs was examined using the Western blot analysis. At 24 h after the burn injury, the level of HSP72 had increased in the hypophysis, lung, heart, and kidney. In all organs examined, the expression of HSP72 had increased at 48 h after the burn injury. The level of HSP72 was highest in the hypophysis (3.3-fold compared to the control), and lowest in the brain and adrenal gland (1.7-fold of the control) at 48 h after the burn injury. These results confirm that severe burn injury causes a stress response in systemic organs. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png European Journal of Plastic Surgery Springer Journals

Abstract

In order to understand the stress response of systemic organs to severe burn injury, the induction of 72-kD heat shock protein (HSP72) in various organs (brain, hypophysis, lung, heart, liver, pancreas, spleen, kidney, adrenal gland, and skeletal muscle) was investigated in rats with severe burns. A full-thickness burn was induced on the rats' skin by immersing the rats in hot water (90° C) for 3 s. At 0, 24, and 48 h after the burn injury, the HSP72 expression of various organs was examined using the Western blot analysis. At 24 h after the burn injury, the level of HSP72 had increased in the hypophysis, lung, heart, and kidney. In all organs examined, the expression of HSP72 had increased at 48 h after the burn injury. The level of HSP72 was highest in the hypophysis (3.3-fold compared to the control), and lowest in the brain and adrenal gland (1.7-fold of the control) at 48 h after the burn injury. These results confirm that severe burn injury causes a stress response in systemic organs.
