FABP4 and gastric adenocarcinoma: These 8 genes (ASCL2, GPR87, F13A1, HDAC11, DCLK1, GCG, FABP4, AXIN2) were regarded as prognostic factors for STAD, and for which the calculation of risk score was: risk score = (−0.016*ASCL2 exp.)+ (0.108*GPR87 exp.)+ (0.052*F13A1 exp.)+ (−0.085*HDAC11 exp.)+ (0.111*DCLK1 exp.)+ (0.088*GCG exp.)+ (0.024*FABP4 exp.)+ (−0.088*AXIN2 exp.).
