Once bound to the CDKN2B promoter, CEBPB stimulates CKDN2B transcription, contributing to cell cycle arrest in oncogene induced senescence (Kuilman et al. 2008). In addition, since CEBPB expression is stimulated by IL6 signaling, with IL6 itself being a transcriptional target of CEBPB (Neihof et al. 2001, Kuilman et al. 2008, Lee et al. 2010), IL6-CEBPB-CDKN2B axis provides an autocrine SASP-mediated growth arrest mechanism.
