As shown in Fig. 7, in comparison with the control group, except for miR-204-5p, the expression levels of ITGA2, FN1, ICAM1, CDH2, TIMP1, CLDN1, TNFRSF12A, miR-146b, and miR-222 were all up-regulated in the tumor group, consistent with the results of the bioinformatics analyses. This evidence concerns the gene CLDN1 and neoplasm.
