Translational inhibition of heat-shock induced gene expression in picornavirus-infected Drosophila melanogaster cells

Abstract

Picornavirus infection of Drosophila melanogaster cells inhibited the appearance of heat-shock induced proteins. Examination of intracellular mRNAs revealed that those coding for heat shock proteins were present in a translationally competent form in infected cells. Inhibition of induced gene expression in infected Drosophila cells therefore involves, but is not necessarily solely mediated by, effects at the level of translation.
