dc.description.abstract | to due to its wide range of commercial and manufacturing uses as a plasticizer. Indeed, DEHP is often found in freshwater systems that receive domestic waste water discharges. Therefore, we evaluated the effects of DEHP on the mRNA levels of heat shock protein (FISP) 40 and 90 in chironomids. In addition. we evaluated the effects of exposure to DEHP on the induction of morphological deformities in chironomids. To accomplish this, partial sequences of HSP 40 and 90 from Chironomus riparius larvae were amplified and sequenced. The inferred amino acid sequences were then aligned with those of other insect HSP 40 and 90 genes. The results of this alignment revealed that there was a high degree of similarity among the homologues. In addition, the FISP 40 and 90 mRNA expressions were significantly upregulated in response to short and long-term exposure to DEHP at concentrations of 1, 10, and 30 mu gL(-1). Furthermore, the Occurrence of mouthpart deformities was significantly higher in chironomids that were treated with DEHP (12-20%) than in controls (3-5%). Taken together, these results indicate that HSP 40 and 90 play important roles in the physiological changes related to metabolism and cell protection that occur in C. riparius larvae that have been exposed to DEHP.
