c-myc is a regulator gene responsible for the upregulation of many genes that promote cell proliferation.[11] The elevated expression of c-Myc has been detected not only in a broad range of human cancers, [11] but also in chronic wounds.[12] The main cause of tracheal stenosis is the excessive cell proliferation that occurs within the limited tracheal space during wound healing. This evidence concerns the gene MYC and cancer.
