ACBD4 and cancer: In addition, our microarray analysis also revealed some novel p53 target genes, such as ACBD4, APOBEC3C, and FLJ14327 (Figures 9 and 10), which would not be identified by simply overexpressing ectopic p53 in cancer cell lines [20], [53], because INZ-activated p53 is acetylated [17], although further studies of these new p53 target genes are necessary to determine whether and how these genes, such as APOBEC3C (Figure 11), might act in the p53 signaling pathway.
