ITGA9 and neoplasm: As is shown in Figure 7, expression level of LAMB1, FN1, ITGAV, LAMA2, LAMA4, TNR, ITGB1, ITGA10 and ITGA9 is higher in tumorous tissues than that of patient‐matched normal tissues (P < .05), whereas other eight genes, such as ITGA11, ITGA5, THBS1, TNN, LAMA5, ITGB5, RELN and LAMC1, express lower in tumorous tissues than patient‐matched normal tissues (P < .05).
