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 .
 IP-10, IP-10 mRNA, IFNgamma, IFNgamma, kB sites, ISRE, IFN stimulus response element ( ISRE ), U937 cells, IP-10, IP-10 mRNA, nuclear proteins
