Brief Summary
Parathyroid hormone (PTH) may play an important role in the down-regulation of CYP3A4 expression induced by Chronic kidney diseases (CKD). In the study of molecular mechanism, the research group found that the expression of CYP3A2 metabolic enzyme in rat liver decreased in the state of CKD.And PTH may down-regulate the expression of CYP3A4 metabolic enzyme by inhibiting the expression of Nuclear factor- Kilobuse (NF-kB) p65 subunit
