A study was conducted to determine the effects of grinding, added N, and the absence of soil on C mineralization from agricultural plant residues with a high C:N ratio. The evolution of CO2 from ground and unground wheat straw, lentil straw, and lentil green manure, with C:N ratios of 80, 36, and 9, respectively, was determined over a period of 98 days.(More)
Glycosphingolipids added exogenously to 3T3 cells in culture were shown to inhibit cell growth, alter the membrane affinity to platelet-derived growth factor binding, and reduce platelet-derived growth factor-stimulated membrane phosphorylation (Bremer, E., Hakomori, S., Bowen-Pope, D. F., Raines, E., and Ross, R. (1984) J. Biol. Chem. 259, 6818-6825). This(More)
Glycosphingolipids added exogenously in cell culture are slowly incorporated into plasma membranes, inhibit cell growth, and modify growth behavior ( Laine , R. A., and Hakomori, S. (1973) Biochem. Biophys. Res. Commun. 54, 1039-1045; Keenan , T. W., Schmid, E., Franke , W. W., and Wiegandt , H. (1975) Exp. Cell Res. 92, 259-270). With the availability of(More)
We previously showed that gangliosides inhibit DNA synthesis in Swiss 3T3 cells stimulated with platelet-derived growth factor (PDGF) in a dose-responsive manner. This correlated with the inhibitory effects of several gangliosides (except GM3) on tyrosine phosphorylation of the PDGF receptor (PDGFR). [35S]Methionine-labeled Swiss 3T3 cells were incubated(More)
Since their discovery in the 1940s, gangliosides have been associated with a number of biological processes, such as growth, differentiation, and toxin uptake. Hypotheses about regulation of these processes by gangliosides are based on indirect observations and lack a clear definition of their mechanisms within the cell. The first insights were provided(More)
Leflunomide, a novel immunosuppressive drug, is able to prevent and reverse allograft and xenograft rejection in rodents, dogs, and monkeys. It is also effective in the treatment of several rodent models of arthritis and autoimmune disease. In vitro studies indicate that leflunomide is capable of inhibiting anti-CD3- and interleukin-2 (IL-2)-stimulated T(More)
Juvenile dermatomyositis (JDM), the most common pediatric inflammatory myopathy, is a systemic vasculopathy affecting young children. Epidemiology studies documenting an antecedent illness in the 3 mo before the first definite symptom (rash and/or weakness) of JDM are supported by immunologic data that suggest that the disease pathophysiology is Ag driven.(More)
Leflunomide is an immunosuppressive drug capable of inhibiting cellular and humoral mediated responses in vivo. The mechanism responsible for suppression of B cell antibody responses in vivo has not been identified. In this study we demonstrate that leflunomide functions to inhibit murine B cell antibody production by directly acting on the B cell.(More)
Pax3 is a transcription factor that is required for the development of embryonic neural tube, neural crest, and somatic derivatives. Our previous study (Mayanil, C. S. K., George, D., Mania-Farnell, B., Bremer, C. L., McLone, D. G., and Bremer, E. G. (2000) J. Biol. Chem. 275, 23259-23266) reveals that overexpression of Pax3 in a human medulloblastoma cell(More)
