Relationship between ribo- and deoxyribonucleotide concentrations and biological parameters in cultured Chinese hamster ovary cells. 1982

D Hunting, and J F Henderson

The relationship between ribo- and deoxyribonucleotide concentrations, growth rate and cell visibility has been studied. Nucleotide pools were manipulated using mycophenolic acid, pyrazofurin, phosphonoacetyl-L-aspartate (PALA) or thymidine. Growth rate, cell viability, nigrosin exclusion, progression through the cell cycle, and the rates of nucleic acid synthesis were measured. The observed qualitative relationships between nucleotide concentrations and growth rate can be rationalized in terms of the effects of changes in substrate availability on nucleic acid synthesis. However, there is no discernible relationship between changes in nucleotide concentrations and the loss of cell viability. More detailed studies will be required to elucidate each step in the complex process leading from the initial changes in nucleotide concentrations to cell death.

UI	MeSH Term	Description	Entries
D009173	Mycophenolic Acid	Compound derived from Penicillium stoloniferum and related species. It blocks de novo biosynthesis of purine nucleotides by inhibition of the enzyme inosine monophosphate dehydrogenase (IMP DEHYDROGENASE). Mycophenolic acid exerts selective effects on the immune system in which it prevents the proliferation of T-CELLS, LYMPHOCYTES, and the formation of antibodies from B-CELLS. It may also inhibit recruitment of LEUKOCYTES to sites of INFLAMMATION.

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.

D010746	Phosphonoacetic Acid	A simple organophosphorus compound that inhibits DNA polymerase, especially in viruses and is used as an antiviral agent.	Phosphonoacetate,Disodium Phosphonoacetate,Fosfonet Sodium,Phosphonacetic Acid,Phosphonoacetate, Disodium
D011720	Pyrazoles	Azoles of two nitrogens at the 1,2 positions, next to each other, in contrast with IMIDAZOLES in which they are at the 1,3 positions.
D002453	Cell Cycle	The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.
