Abstract

To establish cell systems appropriate for investigating the mode of action of antiherpetic nucleoside analogues, mutant cell strains were constructed from murine mammary carcinoma FM3A cells, which were deficient in TK, but were transformed with a recombinant plasmid DNA containing the HSV-2 TK gene. The transformed cells incorporated the viral DNA, expressed viral TK activity and showed unusually high sensitivity to the cytostatic action of the antiherpetic nucleoside analogues ACV and IVDU, both of which were only weakly inhibitory to the growth of the parent cells. Curiously, the FM3A cell strains transformed with HSV-2 TK gene showed a higher sensitivity to ACV and IVDU than the previously established cell line transformed with HSV-1 TK gene. This contrasts with the inhibitory effects of ACV and IVDU on acute HSV infection, since HSV-2 infection is slightly or considerably less susceptible than HSV-1 infection to inhibition by ACV or IVDU, respectively.
