VEGFA and gastric cancer: In the study of PI3K/AKT/mTOR pathway‐related proteins in GC tissues, one found that PI3K AKT, P‐Akt, P‐mTOR, HIF‐1α and VEGF were significantly higher expressed in GC than in paracancerous tissues, whereas there was no difference in mTOR, which was consistent with our findings.54, 55, 56
