When we analyzed the nuclear accumulation of C/EBP-β by immunohistochemistry in PC3-6TR-shIKKε xenografts from mice fed normal diet (Figure 5C) or dox-diet (Figure 5D), we observed a significant decrease of C/EBP-β nuclear staining when IKKε was depleted from the tumor. Here, CEBPB is linked to neoplasm.
