摘要:
The expression of mRNA for five cytochrome P450s (CYP1A1, 2A6/7, 2D6, 2E1 and 3A4) was studied in human bone marrow, bone-marrow-derived macrophages and blood monocyte-derived macrophages. Reverse transcriptase polymerase chain reaction (RT-PCR) detected expression of all Eve CYPs in each of these cell populations, All five CYPs were also expressed in the haemopoietic cell lines HL-60 and HEL and in Epstein-Barr virus (EBV)-transformed B-lymphoblastoid cell lines. The data suggest that bone marrow macrophages and probably other bone marrow cell types are capable of metabolizing xenobiotics. This metabolic potential may play a role in the bone marrow damage induced by some drugs and chemicals.
