| Research Abstract |
This study determines the presence of the new phosphate(Pi)metabolic pathway through the nicotinamide phosphoribosyltransferase(Nampt)as the first rate-limiting enzyme in converting NAM to NAD.The activation of Nampt caused the significantly increased levels of urinary Pi excretion and the decreased levels of intestinal Pi absorption.The present data suggest that the cause of hypophosphatemia and hyperphosphaturia observed after 70% hepatectomy is caused by abnormal Nampt/NAM activation in the liver and kidney.
These result shows presence of the liver-kidney axsis in Pi metabolism.
We examine a mechanism to do constantly the Pi/Ca ratio through Nampt.We think these research may be contribute to the prevention of cardiovascular disease development of patients with chronic renal disease.
