The expression level of CDH23 was significantly reduced in DLBCL tissues than normal tissues in GEPIA database (Figure 1A, p<0.05), GSE32018 dataset from GEO database (Figure 1B, p<0.01) and GSE56315 dataset from GEO database (Figure 1C, p<0.0001). This evidence concerns the gene CDH23 and diffuse large B-cell lymphoma.
