Axonal transport of neuropeptide encoding mRNAs within the hypothalamo-hypophyseal tract of rats.

Mohr, E, Fehr, S, Richter, D

Hypothalamic vasopressin and oxytocin transcripts have been detected in the posterior pituitary suggesting either transcription of the respective genes in pituicytes or axonal mRNA transport from the...

Structural organization of the rat gene for the arginine vasopressin-neurophysin precursor.

Schmale, H, Heinsohn, S, Richter, D

The rat arginine vasopressin-neurophysin precursor gene has been isolated from a genomic library cloned in lambda phage Charon 4A. Restriction mapping and nucleotide sequence analysis demonstrated...

A missense mutation in the vasopressin-neurophysin precursor gene cosegregates with human autosomal dominant neurohypophyseal diabetes insipidus.

Bahnsen, U, Oosting, P, Swaab, D F, Nahke, P, Richter, D, Schmale, H

Familial neurohypophyseal diabetes insipidus in humans is a rare disease transmitted as an autosomal dominant trait. Affected individuals have very low or undetectable levels of circulating...

The gene for the hypothalamic peptide hormone oxytocin is highly expressed in the bovine corpus luteum: biosynthesis, structure and sequence analysis.

Ivell, R, Richter, D

Expression of the vasopressin and oxytocin genes has been described so far only in the hypothalamus. We report here that at least the oxytocin gene is highly transcribed in the bovine corpus luteum...

The mutant vasopressin gene from diabetes insipidus (Brattleboro) rats is transcribed but the message is not efficiently translated.

Schmale, H, Ivell, R, Breindl, M, Darmer, D, Richter, D

The vasopressin gene from normal and diabetes insipidus (Brattleboro) rats has been isolated and sequenced. Except for a single deletion of a G residue in region coding for the neurophysin carrier...

Expression of a mutant vasopressin gene: differential polyadenylation and read-through of the mRNA 3' end in a frame-shift mutant.

Ivell, R, Schmale, H, Krisch, B, Nahke, P, Richter, D

Sequence analysis of cDNA clones derived from hypothalamic mRNA of diabetes insipidus (Brattleboro) rats shows that the vasopressin gene transcript also includes the single base deletion demonstrated...

Reverse physiology in drosophila: identification of a novel allatostatin-like neuropeptide and its cognate receptor structurally related to the mammalian somatostatin/galanin/opioid receptor family.

Birgül, N, Weise, C, Kreienkamp, H J, Richter, D

By using degenerate oligonucleotide primers deduced from the conserved regions of the mammalian somatostatin receptors, a novel G-protein-coupled receptor from Drosophila melanogaster has been...

The operation of the γ-aminobutyrate bypath of the tricarboxylic acid cycle in brain tissue in vitro

Hammond, B. J., Balázs, R., Machiyama, Y., Julian, T., Richter, D.

1. Cerebral-cortex slices prelabelled with γ-amino[1-14C]butyrate (GABA) were incubated in a glucose–saline medium. After the initial rapid uptake there was no appreciable re-entry of 14C into the...

The metabolism of γ-aminobutyrate and glucose in potassium ion-stimulated brain tissue in vitro

Hammond, B. J., Machiyama, Y., Balázs, R., Julian, T., Richter, D.

1. The metabolism of γ-aminobutyrate (GABA) was investigated in cerebral-cortex slices incubated in glucose–saline medium with [1-14C]GABA and [U-14C]-glucose as labelled substrates. 2. A rapid...

Hydration dependence of chain dynamics and local diffusion in L-alpha-dipalmitoylphosphtidylcholine multilayers studied by incoherent quasi-elastic neutron scattering.

König, S, Bayerl, T M, Coddens, G, Richter, D, Sackmann, E

Incoherent quasi-elastic neutron scattering is applied to study the local diffusion and chain dynamics of L-alpha-diplamiotylphosphatidylcholine molecules in oriented model membranes. Different...
