A Chinese hamster ovary leucyl-tRNA synthetase mutant with a uniquely altered high molecular weight leucyl-tRNA synthetase complex
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-04)
The Chinese hamster ovary (CHO) cell culture temperature-sensitive mutant ts 025Cl with a defect in leucyl-tRNA synthetase (LeuRS) does not have an inherently more thermolabile LeuRS, but instead the mutation causes the ...
Epidermal fucosylation of cell surface glycoprotein
(Elsevier, 1984-03-30)
When agglutinin I (UEA) conjugated with fluorescein isothiocyanate is applied to tissue sections from the cutaneous epidermis of the newborn rat, the lectin binds to the surfaces of cells in the layer immediately above ...
Wilms' tumor-aniridia association: Segregation of affected chromosome in somatic cell hybrids, identification of cell surface antigen associated with deleted area, and regional mapping of c-Ha-ras-1 oncogene, insulin gene, and beta-globin gene
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-09)
Fusion of an auxotrophic mutant hamster cell with the skin fibroblasts of a child with the Wilms' tumor-aniridia association produced clones which, on the one hand, contained the child's normal chromosome 11 and, on the ...
In vitro colony formation by cryopreserved primary human tumor cells
(Elsevier, 1984-06)
The effect of cryopreservation on the ability of primary human cancer cells to form colonies in a two-layer agar system was examined. Although considerable variation occurred, concentrations of 5 or 10% dimethylsulfoxide ...
Incorporation of the cytochrome P-450 monooxygenase system into large unilamellar liposomes using octylglucoside, especially for measurements of protein diffusion in membranes
(Elsevier, 1984-05-31)
Cytochrome P-450 and NADPH cytochrome P-450 reductase were incorporated into large unilamellar lipid vesicles (200-300 nm in diameter) removing octylglucoside from mixed micelles by dialysis. The large size of the ...
Isolation and structure of the bacterial sex pheromone, cAD1, that induces plasmid transfer in Streptococcus faecalis
(Elsevier, 1984-12-03)
The Streptococcus faecalis sex pheromone cAD1, which is involved in the conjugative transfer of the hemolysin plasmid pAD1, has been isolated and its structure determined. Its Mr is 818 and its amino acid sequence is ...
Effects of lipoxygenase and cyclooxygenase inhibitors on glucose-stimulated insulin secretion from the isolated perfused rat pancreas
(Elsevier, 1984-04-30)
Some of the metabolites of arachidonic acid formed in the lipoxygenase and cyclooxygenase pathways stimulate insulin release. We studied the relative importance of each of these pathways in the modulation of glucose-induced ...
The nusA recognition site : Alteration in its sequence or position relative to upstream translation interferes with the action of the N antitermination function of phage lambda
(Elsevier, 1984-12-25)
The phage [lambda] transcription antitermination protein, pN, acts with host factors. Nus, at sites on the phage genome, nut, to render RNA polymerase resistant to subsequent downstream termination signals. The NusA protein ...
The consequences of earlier reproduction in declining populations
(Elsevier, 1984-10)
Conflicting claims have been published concerning the consequences of earlier reproduction. In particular, it has been claimed that earlier reproduction will increase the rate of decline in a declining population, have no ...
The effects of ketamine, phencyclidene and lidocaine on catecholamine secretion from cultured bovine adrenal chromaffin cells
(Elsevier, 1984-10-29)
The ability of ketamine, phencyclidine and analogues to alter catecholamine secretion from cultured bovine adrenal chromaffin cells was investigated. Both ketamine and phencyclidine specifically inhibited nicotinic ...
