The interactive effect of elevated temperature on deltamethrin-induced biochemical stress responses in Channa punctata Bloch.
Chem Biol Interact. 2011 Sep 30; 193(3):216-24.CB

Abstract

There are reports showing interactive effect of environmental factors with the toxic outcome of chemicals. We studied the interactive effect of elevated temperature as an abiotic stressor on deltamethrin-induced biochemical stress responses in a freshwater fish, Channa punctata Bloch. Heat stress (∼12°C above ambient temperature for 3h) and pesticide exposure (deltamethrin 0.75ppb for 48h) showed significant induction of heat shock protein-70 (HSP70) in liver, kidney and gills of fishes. Elevated temperature when followed by deltamethrin exposure showed synergistic effect showing a high level of HSP70 in liver and gills whereas response in the kidney was opposite. On the contrary, when deltamethrin exposure followed the heat stress, no significant difference was observed. Protein carbonylation was found to be more pronounced in heat-stressed group compared with control fish group. A significant increase in lipid peroxidation (LPO) was observed in different tissues of fish exposed to either of the stressors. In the kidney of fish exposed to heat stress followed by deltamethrin, LPO was relatively lower as compared to other treatments. Thiols content such as reduced glutathione (GSH), total thiols (T-SH), non-protein thiols (NP-SH) and protein thiols (P-SH) showed no consistent pattern in different tissues. In deltamethrin-exposed group that was subsequently exposed to heat stress, the GSH content was higher in liver and lower in both kidney and gills when compared with other groups. Alteration in the activities of antioxidant enzymes such as catalase (CAT), glutathione S-transferase (GST), glutathione reductase (GR) and glutathione peroxidase (GPx) was also observed when fish were exposed to heat stress and/or deltamethrin. Our study demonstrated that heat stress modulated biochemical stress responses in fish showing a tissue specific pattern. This implies that fish has the capacity to elicit differential response to exposure to abiotic stressors in order to reduce the systemic magnitude of stress which may otherwise lead to severe dysfunction of vital tissues.
