Hypophysectomy of adult male rats abolishes (y2” globulin synthesis; synthesis can be fully restored by daily administration of androgen, thyroid hormone, glucocorticoid and growth hormone for 12 days. It has been previously reported that growth hormone is not required to maintain (ypu globulin mRNA levels, and that growth hormone functions only translatlonally. We have reexamined the role of growth hormone in a2u globulin synthesis using a cloned CQ.” globulin cDNA probe. Measurement of (Ye. globulin mRNA levels by hybridization and cellfree translation, and of (Ye. globulin synthesis by pulse-labeling in vivo, demonstrates that growth hormone is required to maintain full, steady state hepatic levels of both LYE” globulin and its mRNA. Furthermore, the small amount of hepatic CX~” globulin mRNA that accumulates in the absence of growth hormone is efficiently translated in vivo. Thus we now find no evidence for growth-hormonemediated translational control. We have also found that rats hypophysectomized prepubescently respond to the multihormonal restoration therapy to only 10% of the (ypu globulin mRNA levels observed in rats hypophysectomized as adults. This finding suggests that some unidentified pituitary factor (s) is required during puberty to potentiate normal apU globulin gene expression.
