The transport and phosphorylation of 2-deoxy-D-glucose are separate and sequential events in both normal and virus-transformed 3T3 cells. The apparent enhancement of 2-dOG uptake by 3T3 cells accompanying virus transformation is not due to an effect

DNA from a human adult was fragmented by partial digestion with restriction endonuclease EcoRI and cloned in lambda Charon 4A. Clone C15, with a human DNA insert of 17 X 10(3) bases, was identified as containing a gene for the fibroblast interferon,

Using intraspecific hybrids, we have demonstrated the dominant nature of two phenotypic markers present in a mutant mouse 3T6 cell line, designated 3T6-VrB2. These are, resistance to virus infection (Vr) and semiconstitutive synthesis of interferon (

We describe the isolation and characterization of a virus-resistant mutant of murine 3T6 cells. The mutant, designated 3T6-V r B2, displays a high degree of resistance to infection by members of the toga-, rhabdo- and picornavirus classes. The level

Treatment of chick embryo cells growing in culture with rI:rC and many other RNA-like polymers results in the induction of interferon. DEAE dextran is required to facilitate the uptake of the RNA into the cells. Interferon-inducing activity is found

Experimental approaches for selecting hormone-dependent cells, hybrid cells, and haploid cells are discussed. Experiments are described for isolating mammary tumour cells which are dependent on the presence of prolactin and insulin for growth.

The synthesis of vaccinia virus double-stranded ribonucleic acid (RNA) in infected HeLa cells was sensitive to actinomycin D, suggesting that a deoxyribonucleic acid dependent reaction is involved. Some double-stranded RNA was made in the presence of

β-galactosidase (β- d -galactoside galactohydrolase, EC 3.2.1.23) was purified and crystallized from Proteus mirabilis F- lac + and Escherichia coli F- lac + . The preparations were judged to be homogeneous and identical by the criteria of their se

The transfer of the F- lac episome from Escherichia coli into Proteus mirabilis resulted in the anomalous regulation of β-galactosidase (β- d -galactoside galactohydrolase, EC 3.2.1.23) synthesis: the relative efficiencies of various inducers diffe
