Impacts of long-term exposure to sub-lethal verapamil (VRP) at 0.14, 0.28, and 0.57 mg L−1were examined for 60 days to findthe effects on activities of metabolic catalysts as well as molecular reactions in Nile tilapia. Alanine aminotransferase, aspartateaminotransferase, and lactate dehydrogenase activities in the liver increased significantly (p< 0.05) at high concentration of thedrug while there was no significant difference in the activities of soluble phosphatases, corrosive phosphatase, and malatedehydrogenase in comparison with the control. Enzymes of gluconeogenesis, including fructose 1,6-bisphosphatase and glu-cose-6-phosphatase, were induced while RNA/DNA proportion in fish liver decreased significantly in the fish exposed to theVRP from the 15th day onwards. It caused DNA damage and upregulated expression of hsp70,cat,andsod in the liver, whichwere found to be correlated with concentration of the drug. Prolonged exposure to sub-lethal VRP could change activities ofmetabolic catalysts, causing harm to DNA and upregulating stress-related genes in the fish which suggested use of thesebiomarkers as early cautioning signs about the existence of the drug in aquatic ecosystems.
