EGR1 and cancer: Many of the genes identified in the tumor dataset were DNA-binding proteins involved in different processes: some corresponded to genes involved in cancer, such as ABL1, JUN, FOSB, NFKB1A and CCL5; four probes belonged to histones (HIST1H1E, HIST1H4E, HIST1H1D and HIST4H4), others were transcription factors (DDIT3) or genes involved in transcription such as EGR1 and PPP1R15A. Six genes were involved in apoptosis, one of the processes induced by tissue resection.
