title: Protein kinase activities in rat liver nuclei: effects of age and partial hepatectomy.
abstract: Selective substrates and inhibitors have been used to measure kinases phosphorylating endogenous proteins in rat liver nuclei during growth and regeneration after partial hepatectomy. Peaks in activity were found at 5, 22, and 29 hours after partial hepatectomy. Administration of alpha 1 and beta adrenergic blockers suggested that the Be2+ sensitive and cyclic AMP-dependent protein kinases were interdependently regulated by Ca2+ and cyclic AMP.
