IRF8 contributes to coordinate regulation of p53 and p21 by BCL6 and MDM2 in GC B cells. Green arrows and red solid lines indicate transcriptional activation and repression, respectively. Red dashed lines indicate inhibition by induction of protein degradation. Regulatory loops between p53 and BCL6 or MDM2 are shown.
