TGFBR1 and gastric cancer: We also screened eight TRK inhibitors in NCI-N87 (high expression of NTRK1-3 and VEGFR2, but mutation of NTRK3), AGS (high expression of NTRK1-3 and VEGFR2), MKN7 (high expression of NTRK1-3, TGFBR1, and CD274 but VEGFC mutation), SNU16 (low expression of NTRK1-3), and MKN28 (low expression of NTRK1-3) GC cell lines.
