CEBPB and neoplasm: C/EBPβ-2 and C/EBPβ-3 may even comprise a majority of the active, DNA-binding C/EBPs detected within SSC tumor lysates, since in the EMSA experiments there is a correlation between (i), expression levels of the individual proteins C/EBPβ-2 and C/EBPβ-3 (Fig. 3B) and (ii), intensity of C/EBPβ-containing DNA/protein complexes in the EMSA experiments (Fig. 5E); these two parameters are both high for SCC9 and SCC10, and low for SCC12 and SCC13.
