Mammalian cell-virus relationship. III. Poliovirus production by non-primate cells exposed to poliovirus ribonucleic acid.

Summary Exposure of non-primate cells in vitro and in vivo to poliovirus RNA resulted in production of infectious poliovirus, without induction of apparent cytopathogenic effect in vitro or disease in vivo.

Effect of X-Radiation on Uptake of P32 into Individual Nucleotides of HeLa Cells

Summary Separation of 24 acid soluble phosphorus compounds from irradiated and non-irradiated HeLa cells is described. Relative specific activities of 19 of these compounds are given. Irradiation of the cells produced an increase of relative specific activity and amount of uridine diphosphoacetylglucosamine, and a decrease in amount and specific activity of adenosine triphosphate.
