Abstract

Hepatocellular carcinoma (HCC), a globally prevalent form of cancer, is featured by aggressive growth and early metastasis. Elucidating the underlying mechanism and identifying the effective therapy are critical for advanced HCC patients. In the study, we detect that KRT80 was upregulated in HCC samples. HCC patients with higher KRT80 are associated with worse overall survival after surgery. Gain-of and loss-of function studies show that KRT80 enhanced HCC cells proliferation, migration, invasion, and angiogenesis, whereas its silencing abolishes the effects in vivo and in vitro. Mechanistic investigation shows that KRT80 may function as an independent prognostic risk factor and act as an oncogene by influencing EMT and modulating the PI3K/AKT signaling pathway. Together, these findings suggest that KRT80 may be a potential oncogene and a good indicator in predicting prognosis. Targeting KRT80 can offer new insights into the prevention and treatment of HCC.
