Poly(ADP-ribose) polymerase activity is inhibited by 2',5'-oligoadenylates in mouse L-cells.
Down regulation of poly(ADP-ribose)polymerase (ADPRP) activity was observed in mouse LW-cells after treatment with 2'-5'oligoadenylates or with fibroblast interferon and poly(rI) poly(rC). The poly(rI) poly(rC)-induced inhibition of the enzymatic activity correlates with the observed increase of endogenous 2',5'-oligoadenylate cores which were reported to be potent inhibitors of ADPRP in vitro.
