"Given simultaneously, PTH-rP (1 mum) reduced the stimulation of CK activity by PTH(1-84), PTH(1-34), and PTH(28-48) by 94 +/- 9, 79 +/- 8, and 69 +/- 14%, respectively (means +/- S.D., n = 4). In contrast, PTH-rP(7-34) was sufficient to stimulate proliferation of chicken chondrocytes. Thus, PTH-rP exerts different effects on cardiomyocytes and classical target cells for PTH. A synthetic hybrid peptide was synthesized, [Ala29]PTH(28-48), in which alanine replaced glutamine at position 29, as in the PTH-rP molecule. In contrast to PTH(28-48), this mutated peptide [Ala29]PTH(28-48) had no intrinsic activity but antagonized the effect of PTH(1-84) and PTH(28-48) on cardiomyocytes. The results demonstrate that on cardiomyocytes the effect of PTH can be antagonized by PTH-rP. This antagonism seems due to a hydrophobic replacement at position 29." . . "Selventa" . . . .
