ATF3 and neoplasm: This analysis identified a substantial amount of crosstalk between transcription factors from these pathways (Fig. 4d) and highlighted activating transcription factor 3 (ATF3) as a potential integrator of signals from the NFκB, AP-1, and MAF/BACH signaling pathways during the EMT-like process of ependymoma tumor cells (Fig. 4d, e).
