Among proteins whose dysfunctions most frequently contribute to carcinogenesis and tumor progression are the EGFR, which belongs to the ErbB family of tyrosine-kinase receptors that regulate cell proliferation, survival and migration [1,2], as well as the “genome guardian” transcription factor p53 that protects cells against DNA damage and is a tumor suppressor [3,4]. The gene discussed is NTRK1; the disease is neoplasm.
