Steroid Hydroxylases

• 

  Subject Areas on Research

  • A cell-specific nuclear receptor regulates the steroid hydroxylases. 
  • Abnormal parathyroid hormone stimulation of 25-hydroxyvitamin D-1 alpha-hydroxylase activity in the hypophosphatemic mouse. Evidence for a generalized defect of vitamin D metabolism. 
  • Abnormal regulation of renal 25-hydroxyvitamin D-1 alpha-hydroxylase activity in the X-linked hypophosphatemic mouse. 
  • Calcitonin stimulation of renal 25-hydroxyvitamin D-1 alpha-hydroxylase activity in hypophosphatemic mice. Evidence that the regulation of calcitriol production is not universally abnormal in X-linked hypophosphatemia. 
  • Characterization of the effects of tebufelone on hepatic cytochromes P450 in the beagle dog. 
  • Characterization of the mouse FTZ-F1 gene, which encodes a key regulator of steroid hydroxylase gene expression. 
  • Differential effects of vitamin d receptor agonists on gene expression in neonatal rat cardiomyocytes. 
  • Fibronectin-mediated hepatocyte shape change reprograms cytochrome P450 2C11 gene expression via an integrin-signaled induction of ribonuclease activity. 
  • Genetic variants and associations of 25-hydroxyvitamin D concentrations with major clinical outcomes. 
  • Hypercalcemia, hypercalciuria, and elevated calcitriol concentrations with autosomal dominant transmission due to CYP24A1 mutations: effects of ketoconazole therapy. 
  • Induction of rat cytochrome P-450 3 and its mRNA by 3,4,5,3',4',5'-hexachlorobiphenyl. 
  • Measurement of 25-hydroxyvitamin D 1-alpha-hydroxylase activity in mammalian kidney. 
  • Measurement of 25-hydroxyvitamin D-1 alpha-hydroxylase activity in mammalian kidney. 
  • Parathyroid hormone effects on serum 1,25-dihydroxyvitamin D levels in patients with X-linked hypophosphatemic rickets: evidence for abnormal 25-hydroxyvitamin D-1-hydroxylase activity. 
  • Regulation of renal 25-hydroxyvitamin D-1-hydroxylase activity in the mouse after uninephrectomy. 
  • Suppression of male-specific cytochrome P450 2c and its mRNA by 3,4,5,3',4',5'-hexachlorobiphenyl in rat liver is not causally related to changes in serum testosterone. 
  • Suppression of the constitutive, male-specific rat hepatic cytochrome P-450 2c and its mRNA by 3,4,5,3',4',5'-hexachlorobiphenyl and 3-methylcholanthrene. 
  • The endogenous selective estrogen receptor modulator 27-hydroxycholesterol is a negative regulator of bone homeostasis. 
  • The inhibition of human adrenal steroidogenic enzyme activities by suramin.
