Effect of IFN transgene expression on the onset of J2E cell-induced erythroleukemia.
Mice were vaccinated bilaterally with 100 μg IFN DNA in the TA muscle and 14 days later injected with 1 × 106 J2E cells via the tail vein. The cumulative survival was calculated as the mice became moribund (n = 5-7). Vehicle-treated mice were injected with vector DNA without IFN gene cassette.
