Recent reports show that a pre-heat shock has a protective effect against endotoxin “in vivo” in rodents. It has remains unclear what actually confers the protection against endotoxin. One candidate for this protective effect is the heat shock protein of 70 kDa (HSP70). We found that a mild heat shock pretreatment is the rat myogenic cell line, H9c2(2-1), confers resistance to a subsequent exposure to endotoxin. A myogenic rat cell line stably transfected with the human inducible HSP70 exhibits an increased survival rate compared with cells stably transfected solely with the selectable neomycin marker gene or the parental cell line H9c2(2-1) when exposed to endotoxin. The mechanism of endotoxin-induced cell injury is postulated to be through the generation of nitric oxide in these myogenic cells during exposure to endotoxin. We conclude that HSP70, regardless of the particular mechanism of cytotoxicity, plays a role in protecting the cell against the deleterious effects of endotoxin.
