The metabolism of benzo(a)pyrene by Chinese hamster ovary cells in culture. 1980

K Pal, and P L Grover, and P Sims

1. The metabolism off the carcinogenic polycyclic hydrocarbon, benzo(a)pyrene, in Chinese hamster ovary cells in culture has been investigated. 2. Products with the properties on h.p.l.c. of 3-hydroxybenzo(a)pyrene and the trans-4,5-, 7,8- and 9,10-dihydrodiols of benzo(a)pyrene were detected in the cell medium when cells were incubated with benzo(a)pyrene for 24 h. 3. Examination of the nucleoside adducts present in hydrolysates of the DNA of Chinese hamster ovary cells that had been incubated with benzo(a)pyrene showed the presence of a product that co-chromatographed on Sephadex LH20 columns with the nucleoside adduct obtained from DNA that was allowed to react with the anti-isomer of the 7,8-dihydrodiol 9,10-epoxide of benzo(a)pyrene.

D009705	Nucleosides	Purine or pyrimidine bases attached to a ribose or deoxyribose. (From King & Stansfield, A Dictionary of Genetics, 4th ed)	Nucleoside,Nucleoside Analog,Nucleoside Analogs,Analog, Nucleoside,Analogs, Nucleoside
D010053	Ovary	The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.	Ovaries
D002478	Cells, Cultured	Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.	Cultured Cells,Cell, Cultured,Cultured Cell
D003412	Cricetulus	A genus of the family Muridae consisting of eleven species. C. migratorius, the grey or Armenian hamster, and C. griseus, the Chinese hamster, are the two species used in biomedical research.

D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D006224	Cricetinae	A subfamily in the family MURIDAE, comprising the hamsters. Four of the more common genera are Cricetus, CRICETULUS; MESOCRICETUS; and PHODOPUS.	Cricetus,Hamsters,Hamster
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
