Title: [Renal lithostathine: a new protein inhibitor of lithogenesis]. Author: Verdier JM, Dussol B, Casanova P, Daudon M, Dupuy P, Berthezène P, Boistelle R, Berland Y, Dagorn JC. Journal: Nephrologie; 1993; 14(6):261-4. PubMed ID: 8145883. Abstract: Lithostathine is a protein of pancreatic secretion inhibiting calcium carbonate crystal growth. Antibodies to lithostathine were used to identify a related protein in urine and kidney stones. Western blot analysis of proteins extracted from concentrated normal urine or kidney stones demonstrated the presence of a protein with an apparent molecular weight of 23 kDa. The same antibodies were used in immunolocalization experiments on fresh human nephrectomy specimens cryosections. A positive signal was observed in the cells of proximal tubules and thick ascending limbs of Henle's loop. Protein extracts of renal stones inhibited calcium carbonate crystal growth. Because of its structural and functional similarities with pancreatic lithostathine, it was called renal lithostathine.[Abstract] [Full Text] [Related] [New Search]
