For example, studies have shown that the expression of KIF3B (Huang et al., 2014) and KIF26B (Li et al., 2019) is significantly increased in hepatocellular carcinoma (HCC) tissues and HCC cell lines, and the knockout of KIF3B or KIF26B stimulated apoptosis of cancer cells and reduced malignant characteristics of tumors. The gene discussed is KIF3B; the disease is hepatocellular carcinoma.
