Advances of Hedgehog pathway in tumor resistance

Hedgehog pathway regulates the physiological process of tumor cells, including proliferation, cycle, invasion and metastasis, and maintains tumorigenesis and development. With abnomal activation of Hedgehog pathway, most tumors response poorly to chemotherapy, which is mediated by Hedgehog pathway through activation of target gene and crosstalk with other pathways. Herein, Hedgehog pathway has been an important target for reversing resistance. In this study, the Hedgehog pathway and role of Hedgehog-mediated resistance in recent years are reviewed.
