Next, we assessed the correlation between differentially expressed KSP-encoding gene KIF11 and clinical prognosis using the Human Protein Atlas (HPA) database, and the results showed that high expression of KIF11 was associated with dismal overall survival in four cancer types, including renal cancer, liver cancer (hepatocellular carcinoma and intrahepatic cholangiocarcinoma), pancreatic cancer, and lung cancer (Fig. S3A). Here, KIF11 is linked to intrahepatic cholangiocarcinoma.
