by using a glucose microassay and the technique for isolated renal-tubule perfusion in vitro , the addition of 3-mercaptopicolinate , a gluconeogenesis inhibitor which inhibits phosphoenolpyruvate carboxykinase specifically , was found to abolish the effects of parathyroid hormone on gluconeogenesis and phosphate-transport rate in isolated rabbit renal proximal straight tubules , suggesting that these parathyroid-hormone actions may share some unknown , yet 3-mercaptopicolinate-inhibitable , intracellular processes .
