英文摘要
Polycyclic aromatic hydrocarbons induce oxidative and conjugative enzymes
in responsive animals and in human cells. The oxidative enzymes, i.e.,
cytochrome P-450s, generate active intermediates from procarcinogens and
thus initiate chemical carcinogenesis. We propose to investigate this
hypothesis by directly introducing molecularly cloned full length P-450
cDNAs into different cells and analyzing the extent of binding of the
carcinogen to the cellular macromolecules, and the incidence of tumors by
challenging with appropriate carcinogens.
For this purpose, we plan to use the infectious eukaryotic expression
vector, vaccinia virus, which was previously shown to express enzymatically
active foreign proteins that are transported to the appropriate subcellular
site of residence. We have introduced the mouse P1-450 and P3-450 into the
recomination vector and are in the process of transferring these into the
vaccinia virus to generate the infectious recombinant vaccinia virus.
