Regulation of vitamin D-binding protein production by various hormones was studied in an established human hepatoma cell line, HuH-7. Among all the hormones studied, the maximal production of the binding protein was obtained by an extra-cellular addition of triamcinolone or epidermal growth factor. Cell numbers were not so changed except for the addition of insulin or glucagon. Our data indicate that the protein production may be regulated by insulin, estradiol, triamcinolone, dihydrotestosterone or epidermal growth factor.
