ABSTRACT
Biomarkers are extensively used to evaluate the early adverse effects of a toxicant exposure in an organism. Freshwater is exposed to many anthropogenic compounds that adversely affect aquatic life especially, fish population. Effect of acute exposure of low concentrations of BPA (10, 100, 1000 µg/l) on liver cyp1a1 and heat shock proteins mRNA level was evaluated using real time qPCR. Results revealed that exposure to bisphenol A caused decrease expression of cyp1a1 in a concentration dependent manner. Exposure to graded concentrations of bisphenol-A resulted in significant increase in mRNA expression of heat shock proteins (hsp70 and hsp90). In the light of present results, expression of cyp1a1 or heat shock proteins may be used as biomarkers to assess the presence of BPA in the environment.
