The up-regulation of heat shock protein (HSP) expression has been proposed as a general biomarker of cellular protection against various environmental stresses and chemicals. The present study investigated the possibility of using HSP70 up-regulation as a biomarker of toxicant exposure in vitro. Cells of a rat hepatoma cell line (FGC4) were exposed to concentrations of 1,3-dichloroacetone, duroquinone, diquat dibromide, menadione, hydrogen peroxide, cadmium chloride (CdCl2) and sodium (meta)arsenite (NaAsO2) that elicited 20–50% cytotoxicity over a 24
