The expressions of AGRN, CD47, COL11A1, COL1A2, COL3A1, COL4A1, COL4A2, COL5A1, COL5A2, COL5A3, COL6A3, COMP, DAG1, HMMR, ITGA2, ITGA4, ITGAV, ITGB8, LAMB1, LAMB3, LAMC2, SPP1, THBS2, VWF, and SDC1 were significantly highly expressed in gastric cancer, while 11 genes CD36, CHAD, COL4A6, ITGA8, ITGA9, LAMA2, RELN, SV2C, TNXB, LAMB4, and LAMC3 were downexpressed in tumorous tissues (Figure 1(b) and Supplementary Figure 2). Here, LAMB4 is linked to gastric cancer.
