We identified several genes up-regulated by IL-12 , namely, MIP-1alpha , MIP-1beta , IL-1RA , and IFN regulatory factor-1 ( IRF-1 ) .
 ( protein: IRF-1, None) , ( protein: MIP-1alpha, None) , ( protein: MIP-1beta, None) , ( protein: IL-1RA, None) , ( protein: IFN regulatory factor-1 ( IRF-1 ), None) , ( protein: IL-12, None)
