A misaligned double-stranded RNA, poly(I).poly(C12,U), induces accumulation of 2',5'-oligoadenylates in mouse tissues
Abstract:
2',5'-Oligoadenylate synthetase was induced 3-2000-fold in spleen, liver, kidney and brain of NIH Swiss mice injected intravenously with 2-200 micrograms of the misaligned dsRNA, poly(I).poly(C12,U). Levels of 2',5'-oligoadenylates extracted from these tissues were also elevated, although the amount of 2',5'-oligoadenylates extracted did not correlate directly with the amount of enzyme present. These results suggest that double-stranded portions of the misaligned polymer survived intracellularly and activated the 2',5'-oligoadenylate synthetase, and that the level of dsRNA may contribute to the control of 2',5'-oligoadenylate metabolism.
