Effect of a Purified Porcine Relaxin Upon Glycogen and Protein in the Rat Uterus
The recent isolation (Sherwood and O’Byrne, 1974; Frieden et al., 1980) and characterization of porcine relaxin as a two-chain polypeptide bearing a distinct structural similarity to insulin (Schwabe and McDonald, 1977; James et al., 1977) has revived interest in an earlier report (Steinetz et al., 1950) that relaxin can exert glycogenic and protein anabolic effects in ovariectomized, estrogen- treated rats. Since the relaxins used in these early experiments were of relatively low specific activity (10–150 GPU/mg), we have examined the metabolic effects of purified, electrophoretically homogenous porcine relaxin as well as NIH-relaxin.
