Abstract
Synthetic rat atrial natriuretic factor (Ile-ANF-26) stimulated cyclic GMP formation by up to several hundred-fold in osteoblast-rich cultures from newborn rat calvaria and in clonal osteogenic sarcoma cells (UMR 106-01) which are phenotypically osteoblast. ANF had no effect on the cyclic AMP response to parathyroid hormone in the same cells. Specific, high-affinity binding sites for ANF were identified in both cell types, with Kd and receptor numbers in normal osteoblasts of 1.2 +/- 0.1 X 10(-10) M and 42 +/- 4 X 10(3) per cell, and in UMR 106-01 cells of 1.4 +/- 0.1 X 10(-10) M and 22 +/- 4 X 10(3) per cell.Entities:
