KIF23 and hepatocellular carcinoma: By integrating the corresponding clinical features, it was interesting that there was a negative association between KIF23 V1 expression and patients’ OS that patients with positive KIF23 V1 expression displayed a better 5-year OS than those without the expression of KIF23 V1, implying that it might exert a protective role in the progression of HCC, while no significant connection was observed between KIF23 V2 expression and patients’ survival outcomes [125].
