The effects of different dietary fats on peritoneal macrophage plasma membrane fluidity, intracellular cyclic AMP (cAMP) production, GTP hydrolysis and TNF binding and TNF-induced IL1 and IL6 production was investigated. After a four week period, fluidity, as determined by both fluorescence recovery
The effects of: a, maternal diet; b, cyclic-3',5'-adenosinemonophosphate (cyclic AMP) and c, clofibrate on hepatic lipogenesis in fetal rats were studied. The experimental diets contained 22% protein, 40--50% carbohydrate, adequate vitamins, and minerals. In addition, the fat-containing diets were
The activity of phosphoenolpyruvate carboxylase (PEPCase) kinase in leaf extracts increased markedly on dilution. This was shown to be caused by the presence of a protein that inhibits the kinase. The inhibitor protein was separated from the kinase and purified partially. It inhibited the kinase
Transport of tritiated cyclic AMP in the coleoptile of oats (Avena sativa) and corn (Zea mays) is polar, with basipetal to acropetal ratios of 4.0 and 3.2, respectively. The rate of transport is approximately that of indoleacetic acid. The linear velocity of transport, however, is at least five
Previous reports on the incorporation of [(14)C]adenine into adenosine-3':5'-cyclic monophosphate (cyclic AMP) in oat (Avena sativa L.) and maize (Zea mays L.) coleoptile sections, chick-pea (Cicer arietinum L.) embryos and barley (Hordeum vulgare L.) aleurone layers were reexamined. Separation of
In vitro phosphorylation of several membrane polypeptides and soluble polypeptides from corn (Zea mays var. Patriot) coleoptiles was promoted by adding Ca(2+). Ca(2+)-promoted phosphorylation of the membrane polypeptides was further increased in the presence of calmodulin. Both Ca(2+)-stimulated and
