Mitogen-induced expression of IRF-4 mRNA is markedly reduced in c-rel −/− lymphocytes. 10-μg samples of total RNA isolated from untreated or mitogen-stimulated wild-type, nfkb1 −/−, or c-rel −/− splenocytes activated in culture for 2 h were analyzed by Northern blot hybridization. Filters were sequentially hybridized with murine IRF-4 and rat GAPDH cDNA probes and exposed to autoradiography for 24–48 h. Untreated cells (lane 1) and mitogen-activated cells (lanes 2–7). The stimuli were Con A (lane 2); anti-CD3 plus anti-CD28 antibodies (lane 3); phorbol ester (lane 4); LPS (lane 5); anti-RP antibodies (lane 6); and anti-IgM antibodies (lane 7).
