ABSTRACT
Keratinocyte growth factor (FGF-7/KGF) is a secreted member of the fibroblast growth factor family, which functions primarily as an important paracrine mediator of cell growth and differentiation. Inhibitory pathways of vitamin D may also involve participation of some growth factors. To determine whether vitamin D may play a role in the expression of FGF-7, we investigated FGF-7 expression in human breast cancer cells treated with 1,25-dihydroxyvitamin D3, which inhibited the growth of the cells. By means of cDNA microarray, RT-PCR, and Western blot analysis, we have shown an increase in expression of FGF-7 on both mRNA and protein levels after vitamin D exposure. This is the first demonstration of vitamin D regulation of FGF-7 expression and its possible involvement in mediating growth and differentiation by vitamin D.
