Simian virus 40 gene A regulation of cellular DNA synthesis. II. In nonpermissive cells.

abstract：:The mechanism whereby picornaviruses inhibit host protein synthesis while their own synthetic processes proceed unabated has remained elusive. One of our approaches to this problem was to study the ability of cell-free extracts derived from uninfected and mengovirus-infected Ehrlich ascites tumor cells to translate vi...
