In vivo changes of cellulose, trehalose and glycogen during differentiation of Dictyostelium discoideum

Autor: Barbara E. Wright, Per A. Rosness

Publikováno v: Archives of Biochemistry and Biophysics. 164:60-72

Changes in the concentration of three major carbohydrates, e.g., glycogen, trehalose, and cellulose, were determined during differentiation of Dictyostelium discoideum in a stage study. These three carbohydrates consituted 50–63% of the total carbo

Publikováno v: Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism. 488:55-68

1. Testicular 7 alpha-hydroxylation of testerone was assayed in cell extracts of rats between 12 and 79 days of age. Maximal 7 alpha-hydroxylase activity was observed about 60 days, while insignificant activity was obtained prior to 42 days of age. 2

Effects in vitro of medroxyprogesterone acetate on steroid metabolizing enzymes in the rat: Selective inhibition of 3α-hydroxysteroid oxidoreductase activity

Autor: Kristen B. Eik-Nes, Arne Sunde, Per A. Rosness

Publikováno v: Journal of Steroid Biochemistry. 17:197-203

The effects of 6 alpha-methyl-17 alpha-acetoxy-4-pregnene 3,20-dione (MPA) on the activity of different steroid metabolizing enzymes in vitro were investigated in several organs in the rat. MPA seems to be a potent inhibitor of 3 alpha-reduction of 1

Metabolism of 5α-androstane-3β,17β-diol to 17β-hydroxy-5α-androstan-3-one and 5α-androstan-3α,17β-diol in the rat

Autor: Kristen B. Eik-Nes, Per A. Rosness, Arne Sunde

Publikováno v: Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism. 574:240-247

Significant metabolism of 5 alpha-androstane-3 beta,17 beta-diol to 17 beta-hydroxy-5 alpha-androstan-3-one was recorded in several tissues and organs from rats and humans. This bioconversion was further investigated in rat testis homogenates. 5 alph

Effects of Adenosine 3′,5′-Monophosphate and Adenosine 5′-Monophosphate on Glycogen Degradation and Synthesis in Dictyostelium discoideum

Autor: Per A. Rosness, Gary L. Gustafson, Barbara E. Wright

Publikováno v: Journal of Bacteriology. 108:1329-1337

Data are presented demonstrating that the presence in vivo of adenosine 3′,5′-monophosphate (3′,5′-AMP) causes a rapid depletion of glycogen storage material in the cellular slime mold. The effect of adenosine 5′-monophosphate (5′-AMP) is

Cellulolytic Enzymes During Morphogenesis in Dictyostelium discoideum

Autor: Per A. Rosness

Extracts from Dictyostelium discoideum at the sorocarp stage of development catalyzed the degradation of acid-swollen cellulose to d -glucose at an optimal p H of about 4.5; cellobiose and cellotriose were the major products from this degradation at
