The human (h) TXA2 receptor (TP), a G protein-coupled receptor, exists as two isoforms, TPalpha and TPbeta, which arise by alternative mRNA splicing and differ exclusively in their carboxyl terminal cytoplasmic regions. ...
We have investigated the functional coupling of alpha and beta isoforms of the human thromboxane A2 receptor (TP) to Galpha16 and Galpha12 members of the Gq and G12 families of heterotrimeric G proteins in human embryonic ...
Since its discovery in 1975, we now have a wealth of knowledge relating to the biochemical, pharmacological and physiologic actions of thromboxane (TX) A2 and its related metabolites. These molecular insights have been ...
Both thromboxane (TX) A2 and 8-epi prostaglandin (PG) F2alpha have been reported to stimulate mitogenesis of vascular smooth muscle (SM) in a number of species. However, TXA2 and 8-epiPGF2alpha mediated mitogenic signalling ...
Thromboxane (TX) A2 and prostaglandin (PG) D2 mediate opposing actions in platelets and in vascular and non-vascular smooth muscle. Here, we investigated the effects of stimulation of the PGD2 receptor (DP) on signaling ...
In humans, thromboxane (TX) A2 signals through two TXA2 receptor (TP) isoforms, termed TPalpha and TPbeta, that diverge exclusively within their carboxyl terminal cytoplasmic domains. The amino terminal extracellular ...
The human thromboxane (TX)A2 receptor (TP) gene encodes two TP isoforms, TPalpha and TP beta that are regulated by distinct promoters designated promoter (Prm) 1 and Prm3, respectively. Previous studies established that ...
Thromboxane (TX) A2 is a potent stimulator of platelet activation/aggregation and smooth muscle contraction and contributes to a variety of pathologies within the vasculature. In this study, we investigated the mechanism ...
Fluorinated amino acids are used as enzyme inhibitors, mechanistic probes and in the production of pharmacologically active peptides. Because enantiomerically pure 4-fluoroglutamate is difficult to prepare, the selective ...
In humans, thromboxane (TX) A2 signals through the TPalpha and TPbeta isoforms of the TXA2 receptor that exhibit common and distinct roles. For example, Gq/phospholipase (PL)Cbeta signaling by TPalpha is directly inhibited ...
The human prostacyclin receptor (hIP) undergoes agonist-induced internalization but the mechanisms regulating its intracellular trafficking and/or recycling to the plasma membrane are poorly understood. Herein, we conducted ...
The degradation of fluoroacetate by microorganisms has been established for some time, although only a handful of dehalogenases capable of hydrolyzing the stable C-F bond have been studied. The bacterium Pseudomonas ...
The biosynthesis of the pyrrolylpolyene rumbrin (1) in the fungus Auxarthron umbrinum was elucidated using feeding studies with labelled precursors. Incorporation of stable isotopes from [15N]-proline, [13C]-methionine and ...
Some iturin A-producing strains of Bacillus subtilis will elaborate the novel fluorinated analogue when incubated with 3-fluoro-L-tyrosine. The activity of iturin A is dependent on the D-tyrosine residue and the presence ...
Prostacyclin plays a central role in haemostasis, inflammation and nociception. However, the factors regulating expression of the prostacyclin receptor (IP) gene in humans, or in other species, have not been identified. ...
The peptide-derived glyoxal inhibitor Z-Ala-Ala-Phe-glyoxal has been shown to be ~10 fold more effective as an inhibitor of subtilisin than Z-Ala-Pro-Phe-glyoxal. Signals at 107.2 p.p.m. and 200.5 p.p.m. are observed for ...
In humans, TPα and TPβ isoforms of the thromboxane A2 receptor are transcriptionally regulated by distinct promoters, designated Prm1 and Prm3. Previous investigations identified two upstream repressor regions (URR) 1 and ...
Thromboxane plays an essential role in haemostasis, regulating platelet aggregation and vessel tone. In humans, it signals through the TPalpha and TPbeta isoforms that are transcriptionally regulated by distinct promoters, ...
The fungus Cunninghamella elegans is a useful model of human catabolism of xenobiotics. In this paper, the biotransformation of fluorinated biphenyls by C. elegans was investigated by analysis of the culture supernatants ...
Prostacyclin and the prostacyclin receptor (IP) are implicated in mediating many of the atheroprotective effects of estrogen in both humans and in animal models but through unknown mechanisms. Hence, herein the influence ...
