The Vitamin D Receptor-BIM Axis Overcomes Cisplatin Resistance in Head and Neck Cancer.

ABSTRACT: Treatment success of head and neck squamous cell carcinoma (HNSCC) is often hindered by cisplatin resistance. As inherent and acquired therapy resistance counteracts improvement in long-term survival, novel multi-targeting strategies triggering cancer cell apoptosis are urgently required. Here, we identify the vitamin D receptor (VDR) as being significantly overexpressed in tumors of HNSCC patients (n = 604; p = 0.0059), correlating with tumor differentiation (p = 0.0002), HPV status (p = 0.00026), and perineural invasion (p = 0.0087). The VDR, a member of the nuclear receptor superfamily, is activated by its ligand vitamin D (VitD) and analogs, triggering multiple cellular responses. As we found that the VDR was also upregulated in our cisplatin-resistant HNSCC
