Overexpression of KIF23 was detected in squamous cell carcinoma,[22] gastric cancer,[23] breast cancer,[24] and lung cancer.[25] In this study, integrating four gene expression datasets covering DLBCL patients and normal tissues, we identified that KIF23 expression showed a remarkable discrepancy between normal tissues and tumor tissues of DLBCL. The gene discussed is KIF23; the disease is breast carcinoma.
