To define further the relation between Stat3 activation and enhanced IgM production , we determined the effect of chimeric gp130 on the transcriptional activation of a genetic element linked to immunoglobulin production , namely the immunoglobulin heavy chain enhancer ( IgH-enhancer ).
 ( protein: Stat3, None) , ( protein: immunoglobulin, None) , ( DNA: IgH-enhancer, None) , ( DNA: immunoglobulin heavy chain enhancer, None) , ( protein: IgM, None)
