KLK3 and neoplasm: These results revealed that Neu_c04_GPR183, Neu_c05_HSP, Neu_c07_KLK3 and Neu_c09_HLA tended to be distributed in tumor tissues, suggesting that they may be TANs, whereas Neu_c01_THBS1, Neu_c02_S100A12, Neu_c03_IFITM2, Neu_c06_JUN, Neu_c08_CD69 and Neu_c10_FCER1A tended to be distributed in normal tissues, suggesting that they may be NANs (Figure 5D).
