VD exerts its functions through the vitamin D receptor (VDR), a nuclear transcription factor that regulates the expression of VD3-responsive target genes. Notably, divergent findings across studies have been reported regarding VDR expression patterns and functional roles, underscoring the complexity of VDR in cancer biology. Whether this complexity interferes with VD’s biological activity-thereby contributing to the variable impacts of VD3 on cancer prevention and treatment-remains unclear. This review systematically addresses: (1) the association between VDR expression (assessed by immunohistochemistry) and cancer prognosis; (2) the roles and mechanisms of VDR in cancer; (3) the multi-level regulatory networks governing VDR expression and activity; and (4) the translational implications of VDR in cancer therapy. Elucidating the precise roles and mechanisms of VDR is critical for optimizing cancer treatment strategies and resolving conflicting clinical evidence.Keywords: vitamin D receptor, cancer, prognosis, function and mechanism, therapy
