FIG. 8.
Sodium butyrate induces the expression of IRF-7. (A) RPA was performed with IRF-7 and GAPDH probes with RNAs from DG75 cells. Lane 1, untreated cells; lanes 2 to 4, treatments with 3, 5, and 10 mM sodium butyrate for 24 h, respectively. Specific RNA protections are shown. Bottom panel, short-time exposure for GAPDH-protected areas.
