During the tumor initiation processes, ERK activity dynamics are likely to be changed to promote cell proliferation, as intestinal organoids derived from adenomas developed in Apc mutant mice [71] exhibit altered ERK activity dynamics: the ERK activity pulses are increased in an EGFR-dependent manner and the basal ERK activity is also dependent on EGFR signaling in adenoma organoids [35]. This evidence concerns the gene EGFR and neoplasm.
