ObjectiveTo summarize the biological function and molecular regulation mechanism of serine threonine tyrosine kinase 1 (STYK1) in tumor occurrence and development. MethodThe relevant literature about STYK1 and tumor progression in recent years was searched and reviewed. ResultsThe expression of STYK1 was up-regulated in a variety of tumors and was related to the prognosis. STYK1 might regulate the proliferation, apoptosis, migration, metastasis, aerobic glycolysis, drug resistance and other biological functions of tumor cells through MEK/ ERK, PI3K/AKT, JAK/STAT and their targeting proteins, and promote the malignant progress of tumors. Conclusion STYK1is expected to become a new target for the treatment of malignant tumors, but the molecular mechanism of its regulation of tumor progression and its upstream regulators need to be further explored.
