Increased expression of IFNgamma -induced IP-10 mRNA following the differentiation of U937 cells was mediated largely by augmented transcriptional activity of the gene and was related to differentiation-dependent changes of the proteins bound to IFN stimulus response element ( ISRE ) and kB sites , suggesting that these nuclear proteins may determine the IP-10 mRNA inducibility by IFNgamma .
