FGFBP1 and oral cavity squamous cell carcinoma: In oral squamous cell carcinoma cells, the 1,25-(OH)2D3 analogue Eldecalcitol antagonizes the mitogenic action of fibroblast growth factor (FGF)1/2 by repressing nuclear factor kappa B (NF-kB) and inducing miR6887-5p, which targets 3′UTR mRNA of heparin-binding protein 17/FGF-binding protein-1 (HBp17/FGFBP-1), a FGF2 chaperone [147,148].
