CYP2W1 and cancer: Importantly, we detected CYP isoforms with established roles in drug metabolism; CYP2W1, CYP2J2, and CYP1A1, expressed uniquely in additional cancer cell lines (A253, C106, COLO-205, Detroit-562, FADU, LS174T, OSC-19, SSC9), transfected lines (CHO-1A1, SW480-2W1, SW480-mock), and xenografts (DLD-1-Xeno, HT55-Xeno, CHO-1A1-Xeno), which have not been previously reported.
