We have studied the de novo biosynthesis and secretion of LH subunits in pituitary quarters from orchiectomized and intact control adult male rats and their regulation by GftRH. After labeling with [35S]cystine ([35S]Cys), [35S]methionine, or [3H]glucosamine ([3H]GlcN) in the presence or absence of 10−8 M GnRH, tissue lysates arid media were immunoprecipitated with antisera to LHβ, then LHα (after removal of TSH by immunoprecipitatiori with ariti-TSHβ), and the products were analyzed by sodium dodecyl sulfate gradient gel electrophoresis. During a 12-min pulse labeling with [35S]rriethionine, three forms of immunoreactive a were labeled at 21,000, 18,000, and 12,000 mol wt. After a 30-min chase with excess unlabeled methionine, the 12,000 form decreased from 10% to 3% of total radioactivity, while the 21,000 form increased from 57% to 69%, implying a precursor-product relationship. Neither orchiectomy nor GnRH had any effect on [35S]Cys or [3H]GlcN incorporation into intracellular or secreted total protei...
