J A Schetz et al.
Molecular pharmacology, 57(1), 144-152 (2000-01-05)
The molecular determinants that govern selective ligand binding to the rat D(4) dopamine receptor were investigated by substituting D(2) dopamine receptor sequences into a D(4) dopamine receptor background. The resulting mutant D(4) dopamine receptors were then screened with a panel
S Patel et al.
Molecular pharmacology, 50(6), 1658-1664 (1996-12-01)
We identified a novel azaindole derivative, L-750,667, that has high affinity (Ki = 0.51 nM) and >2000-fold selectivity for D4 dopamine receptors compared with its activity at D2 and D3 dopamine receptors. L-750,667 had little affinity for rat D1/D5 dopamine

The transcriptomes of Salmonella enterica serovar Typhimurium SL1344 lacking a functional ramA or ramR or with plasmid-mediated high-level overexpression of ramA were compared to those of the wild-type parental strain. Inactivation of ramA led to increased expression of 14 SPI-1

The dissociable sigma subunit of bacterial RNA polymerase is required for the promoter-specific initiation of transcription. When bound to RNA polymerase, sigma makes sequence-specific promoter contacts and plays a crucial role in DNA melting. In isolation, however, sigma lacks significant

Circulation, 111(3), 356-362 (2005-01-19)
Previous studies have shown that adrenomedullin (AM) inhibits vascular endothelial cell apoptosis and induces angiogenesis. We investigated whether AM enhances bone marrow cell-induced angiogenesis. Immediately after hindlimb ischemia was created, rats were randomized to receive AM infusion plus bone marrow-derived
