Time course effect of IFN-γ on the expression of IRF-1 and iNOS (A). Total RNAs were isolated from ESTDAB-159 cell line and form the control cell line ESTDAB-056 grown in the presence or absence of 800 U/ml IFN-γ for the indicated periods of time and analyzed for the relative levels of mRNA by RT-PCR.
