Modeling of gene expression pattern alteration by p,p'-DDE and dieldrin in largemouth bass

Abstract

In this study, largemouth bass (LMB) were subchronically exposed to p,p'-DDE or dieldrin in their diet to evaluate the effect of exposure on expression of genes involved in reproduction and steroid homeostasis. Using real-time PCR, we detected a different gene expression pattern for each OCP, suggesting that they each affect LMB in a different way. We also detected a different expression pattern among sexes, suggesting that sexes are affected differently by OCPs perhaps reflecting the different adaptive responses of each sex to dysregulation caused by OCP exposure.
