Inhibition of Rous sarcoma virus production by formycin. 1985

L Sarih, and B Agoutin, and O Lecoq, and D Weill, and P Jullien, and T Heyman

The effect of formycin, an adenosine analog, on the growth of chick embryo fibroblasts and on Rous sarcoma virus (RSV) production was studied. An adverse effect on cell proliferation was observed in the presence of 10 microM formycin. Treatment with 5 microM formycin for 24 hr reduced by a factor of about 1000 the yield of infections progeny whereas the cell growth remained unaltered. Moreover the few particles released in the presence of formycin showed a markedly decreased ability to synthesize viral cDNA. This impairment was shown to be related to a nonfunctional primer tRNA.

D002642 Chick Embryo The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching. Embryo, Chick,Chick Embryos,Embryos, Chick
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).
