we used cultured skin fibroblasts from patients with hereditary resistance to 1,25-dihydroxyvitamin d [ 1,25- ( oh ) 2d ] and normal hormone binding to soluble extract from cells [ i.e . receptor-positive resistance to 1,25- ( oh ) 2d ] to characterize dna binding of the receptor for 1,25- ( oh ) 2d .
