The identification of target proteins of C/EBPαp30 from 2D gels with or without β-estradiol induction. Enlarged view of some of the spots taken from the gel image. Each spot represents the zoom view of 2D gel spots induced by C/EBPαp30 in K562C/EBPαp30-ER cells after β-estradiol induction. (A) Protein spots identified as up-regulated targets. (B) Protein spots identified as down-regulated targets of C/EBPαp30 after β-estradiol induction. The value(s) are calculated as a mean normalized spot volume obtained from the ProteomWeaver software.
