In summary, our study indicates that the tumour suppressive role of NOTCH1 in OSCC is manifested, at least in part, by ETV7-mediated suppression of SERPINE1. We have identified the NICD/TEL2/SERPINE1 regulatory axis as a stratification and prognostic tool in OSCC that may be valuable for developing new treatments. This evidence concerns the gene ETV7 and neoplasm.
