3-hydroxy 3-methylglutaryl coenzyme A reductase: a new biomarker of fish exposure to water pollution.
The aim of this study was to identify a new putative biomarker in Salmo trutta exposed to water pollution. Variations in the levels of hepatic 3-hydroxy 3-methylglutaryl Coenzyme A reductase (HMG-CoAR), the rate-limiting enzyme of cholesterol biosynthesis, were compared to heat shock protein 70 and hypoxia inducible factor α, biomarkers of pollution exposure and lowered O₂, respectively. The results confirm that HMG-CoAR levels increase in polluted water irrespective of water temperature or O₂ content, indicating that HMG-CoAR could be used as a specific biomarker for water pollution.
