vitamin k deficiency in rats caused a rise of in vivo occupied 1,25 ( oh ) 2d3 receptor level in chromatin of the intestinal mucosa and a marked ( 2-2.5-fold ) increase of intestinal cytosolic 1,25 ( oh ) 2d3-receptor complex binding with heterologous dna , whereas maximum binding capacity and equilibrium dissociation constant of cytosolic 1,25 ( oh ) 2d3 receptors did not change .
