when chick embryo fibroblasts infected with high multiplicities of a non-revertible temperature-sensitive ( ts ) mutant ( ts53 ) of newcastle disease virus ( ndv ) at the permissive temperature ( 34 degrees c ) and incubated to allow the appearance of virus-induced proteins were shifted up to and incubated at the non-permissive temperature ( 42 degrees c ) , analysis of [ 3h ] leucine-labelled proteins by sds-page revealed a marked increase in cellular protein synthesis and a decline in viral synthesis , with an eventual return to an apparently uninfected state .
