The distribution and dissociation of cyclic adenosine 3':5'-monophosphate-dependent protein kinases in adipose, cardiac, and other tissues
Autor: S L Keely, J D Corbin, Charles R. Park
Publikováno v: Journal of Biological Chemistry. 250:218-225
In crude extracts of adipose tissue the protein kinase dissociates slowly at 30 degrees into regulatory and catalytic subunits in the presence of 700 mug per ml of histone or 0.5 M NaCl. If the kinase is first dissociated by adding 10 muM adenosine 3

Enhancement of free radical reduction by elevated concentrations of ascorbic acid in avian dystrophic muscle
Autor: Jane H. Park, William E. Serafin, Albert H. Beth, Ray C. Perkins, L. S. Wilkerson, Charles R. Park, Larry R. Dalton
Publikováno v: Proceedings of the National Academy of Sciences. 77:790-794
It has been postulated that the degenerative process in dystrophic muscle results from increased concentrations of free radicals, peroxides, or lipid hydroperoxides. Therefore, the reduction of the free radical tanol (2,2,6,6-tetramethyl-4-piperidino

Effects of glucagon on cyclic AMP and carbohydrate metabolism in livers from diabetic rats☆
Autor: Roger A. Johnson, Simon J. Pilkis, John H. Exton, Charles R. Park
Publikováno v: Biochimica et Biophysica Acta (BBA) - General Subjects. 343:250-267
Cyclic AMP metabolism in normal and diabetic livers was studied using the isolated perfused rat liver and plasma membrane and supernatat fractions from rat liver. Liver from alloxan- or streptozotocin-diabetic rats had increased tissue levels of cycl

On the question of translocation of heart cAMP-dependent protein kinase
Autor: S L Keely, J D Corbin, Charles R. Park
Publikováno v: Proceedings of the National Academy of Sciences. 72:1501-1504
Rat hearts were perfused with epinephrine and/or 1-methyl-3-isobutylxanthine for 2 min. These agents raised the concentration of cAMP and increased the fraction of cAMP-dependent protein kinase (EC 2.7.1.70) in the active form. However, the content o

Transport of D-allose by isolated fat-cells: An effect of adenosine triphosphate on insulin stimulated transport
Autor: E. G. Loten, David M. Regen, Charles R. Park
Publikováno v: Journal of Cellular Physiology. 89:651-660
D-allose, a glucose analogue, is not metabolized by isolated fatcells and its distribution space at equilibrium in the cells is the same as that of tritiated water. Uptake of allose is inhibited by glucose and 3-0-methylglucose, stimulated by insulin

Equilibrium binding of spin-labeled fatty acids to bovine serum albumin: suitability as surrogate ligands for natural fatty acids
Autor: Albert H. Beth, Ray C. Perkins, Charles R. Park, Jane H. Park, Larry R. Dalton, Nada A. Abumrad, K. Balasubramanian
Publikováno v: Biochemistry. 21:4059-4064
Electron paramagnetic resonance (EPR) and saturation transfer EPR (ST-EPR) spectroscopies were used to characterize the binding of spin-labeled fatty acid (SLFA) to bovine serum albumin (BSA). Association constants of three stearic acid derivatives l
