✦ Synopsis

Total poly (A)+mRNA was isolated from mengovirus-infected Ehrlich ascites tumor cells at various times postinfection and quantitated in a cell-free system derived from uninfected ascites cells. Basic proteins were separated from acidic proteins by carboxymethyl cellulose chromatography. At the end of the infectious cycle, 8h postinfection, the cellular contents of most mRNAs coding for basic ribosomal proteins are still between 70 and 90 percent of those measured at the beginning of infection or in uninfected cells. On the basis of this result, the rapid shutoff of host protein synthesis after mengovirus infection of Ehrlich ascites tumor cells cannot be the consequence of the inactivation of host template RNA.
