We now demonstrate that CCAAT / enhancer - binding protein ( C / EBP ) delta is a major component of a PGE2 - stimulated DNA - protein complex involving HS3D and find that C / EBPdelta transactivates IGF - I promoter 1 through this site .
 GENE: CCAAT / enhancer - binding protein ( C / EBP ) delta; GENE: HS3D; GENE: C / EBPdelta; GENE: IGF - I promoter 1
