for the evaluation of the drug metabolic characteristics of CYP3A22. Methods Sus scrofa CYP3A22 gene obtained by PCR was cloned into the eukaryotic expression vector pcDNA3.1 [The tissue of Bama minipig was amplified by RT-PCR. The gene was subcloned into plasmid pMD18-T (designated as pMD-3A22)
and then the gene amplified by recombinant plasmid was designated as pcDNA-3A22
]
. Then Sus scrofa CYP3A22 gene was
confirmed by sequencing. Next
the confirmed gene was transfected into HepG
2
cells by lipid-media transfection
and the transformant HepG
2
cells were screened by G418 for 10 generations. Expression of CYP3A22 in HepG
2
cells was identified by RT-PCR and Western blot analyses
and the metabolic activity of transformant HepG
2
(HepG
2
-CYP3A22) was verified by nifedipine oxidation. Results The HepG
2
-CYP3A22 line demonstrated a significantly higher oxidative activity as compared with the negative control HepG
2
line. Conclusion HepG
2
cell line stably expressing CYP3A22 was established successfully. The cell line may be useful for the studies of toxicity and pharmacology.
