Modulation of CYP1A1-mediated oxidation of carcinogenic azo dye Sudan I and its binding to DNA by cytochrome b5.
OBJECTIVES: Modulation of the cytochrome P450 (CYP) 1A1-mediated oxidative activation and detoxication of carcinogenic Sudan I by the heme-protein cytochrome b(5) (b(5)) was investigated. Another aim of the study was to examine the formation of Sudan I-DNA adducts in vivo.
METHODS: High performance liquid chromat.....
