The TPR-MET oncogenic rearrangement is present and expressed in human gastric carcinoma and precursor lesions..     ///     The TPR-MET oncogenic rearrangement was originally observed in an in vitro transformed human osteosarcoma cell line.     ///    We report here the results of analysis of TPR-MET expression in cell lines derived from human gastric tumors and 22 biopsy samples of human gastric mucosa showing cancer or precursor lesions.     ///    Overexpression of TPR-MET RNA in superficial gastritis lesions with hyperplasia of glandular neck cells suggests the possible involvement of this oncogene at an early stage of gastric tumorigenesis.
