FIG. 6.

Northern blot analysis of uninduced and induced KSHV-BJAB cells. BCBL-1 cells and KSHV-BJAB cells were induced by Adeno-50 (Ad50) plus 2 mM sodium butyrate (NaB). Forty-eight hours postinduction, mRNA was extracted and analyzed. BJAB cells were included as a negative control. Uninduced and induced BCBL-1 cells were included as a positive control. (A) Northern blot probed with radiolabeled sequences containing viral cyclin (vCyclin), PAN RNA, and GAPDH consecutively. (B) Northern blot probed with vIL-6 and GAPDH consecutively.
