1 Only CES2 gene expression correlated with the carboxylesterase activity assays (P < 0.01) with CPT-11 and 4-methylumbelliferyl acetate as substrates. Irinotecan carboxylesterase 2 Homo sapiens
2 CONCLUSIONS: We conclude that CES2 is the most abundant carboxylesterase in colon tumors that is responsible for CPT-11 hydrolysis. Irinotecan carboxylesterase 2 Homo sapiens
3 This pilot study reinforces the hypothesis that there is a large interindividual variation in expression of carboxylesterases that may contribute to variation in therapeutic outcome and/or toxicity of CPT-11 therapy for colon cancer. Irinotecan carboxylesterase 2 Homo sapiens
