ISLR and gastric cancer: Several paired genes including (f2r, islr), (fn1, col1a1), (islr, col1a1), (islr, f2r), (pdgfrb, col1a1), (pdgfrb, f2r), and (vcan, col1a1) showed a positive correlation with each other, so that using antagonists against both of them could have a synergistic effect on the gastric cancer survival.
