In contrast, another inducible gene expression of monocyte chemotactic protein-1 (a CC chemokine ) and the activation of the transcriptional factor ( FcRFgamma ) bound to the gamma response region were similarly or less abundantly induced by IFNgamma treatment in PMA -or RA -differentiated U937 cells , indicating that increased IP-10 mRNA induction was not due to the augmented ability of the cells to respond to the presence of IFNgamma .
 protein: monocyte chemotactic protein-1; cell line: U937 cells; RNA: IP-10 mRNA; protein: FcRFgamma; protein: CC chemokine; protein: IFNgamma; protein: transcriptional factor; protein: IFNgamma; DNA: gamma response region; protein: IP-10
