VDR and squamous cell carcinoma: In this report, DNA array analysis of 1,25D-regulated genes in squamous cell carcinoma cells in vitro (Akutsu et al., 2001; Lin et al., 2002) was combined with in silico analysis of genomic VDR binding sites to provide a comprehensive overview of potential 1,25D-VDR target genes (Wang et al., 2005).
