Fig. 5. IFN- effects on c-myc and Cdc25A expression. Analysis of c-myc and Cdc25A regulation in quiescent (Day 0), PHA-treated (Day 3), IL-2-treated (Days 46), and IL-2/IFN--treated (Days 46) cells by immunoblotting (A), Northern blot analysis (B), and immunoblotting (C). Tubulin (A and C) and 18S and 28S rRNA (B) served as controls for equal loading.
