On the basis of the connections of GC to Src, mTOR, Aurora A, and HSP90, their corresponding clinically promising inhibitors, dasatinib, everolimus, alisertib, and ganetespib,11, 28 were assessed in GC cell lines, including MGC-803, SGC-7901, and MKN-28 cells, and normal gastric mucosal epithelial cell line GES-1. This evidence concerns the gene SRC and gastric cancer.
