Guanosine-5'-O-(3-thiotriphosphate) modifies kinetics of voltage-dependent calcium current in chick sensory neurons. [PDF]

Biophys J, 1989
Internal perfusion with the G-protein activator guanosine-5'-O-(3-thiotriphosphate) (GTP-gamma S) mimics the effect of noradrenaline and dopamine on the voltage-dependent calcium current in chick dorsal root ganglion (DRG) cells. With 100 microM GTP-gamma S in the pipette, the current at +10 mV was depressed by approximately 50%, with a 10-fold ...

Lack of the Transient Receptor Potential Vanilloid 1 Shifts Cannabinoid-Dependent Excitatory Synaptic Plasticity in the Dentate Gyrus of the Mouse Brain Hippocampus [PDF]

Frontiers in Neuroanatomy, 2021
The transient receptor potential vanilloid 1 (TRPV1) participates in synaptic functions in the brain. In the dentate gyrus, post-synaptic TRPV1 in the granule cell (GC) dendritic spines mediates a type of long-term depression (LTD) of the excitatory ...

Functional Interaction Between Caveolin 1 and LRRC8-Mediated Volume-Regulated Anion Channel [PDF]

Frontiers in Physiology, 2021
Volume-regulated anion channel (VRAC), constituted by leucine-rich repeat-containing 8 (LRRC8) heteromers, is crucial for volume homeostasis in vertebrate cells.

Intracellular application of guanosine-5'-O-(3-thiotriphosphate) induces exocytotic granule fusion in guinea pig eosinophils. [PDF]

J Exp Med, 1990
The mechanism of eosinophil secretion was studied in guinea pig eosinophils by measuring release of hexosaminidase from cell suspensions (greater than 98% pure) permeabilized with streptolysin-O and by whole-cell patch-clamp capacitance measurements. It is shown that release of eosinophil granule components occurs by an exocytotic mechanism in which ...

Inositol 1,4,5-trisphosphate- and guanosine 5'-O-(3-thiotriphosphate)-induced Ca2+ release in cultured airway smooth muscle. [PDF]

Br J Pharmacol, 1991
The interaction between inositol 1,4,5‐trisphosphate (InsP3) and guanosine 5′‐O‐(3‐thio triphosphate) (GTPγS) releasable calcium (Ca2+) pools was examined using 45Ca effluxes in permeabilized cultured airway smooth muscle cells from rabbit trachea. Addition of InsP3 or GTPγS caused a concentration‐dependent release of intracellular Ca2+.

Induction of neurite formation in PC12 cells by microinjection of proto-oncogenic Ha-ras protein preincubated with guanosine-5'-O-(3-thiotriphosphate). [PDF]

Mol Cell Biol, 1987
Rat pheochromocytoma (PC12) cells differentiate to neuronal cells in response to nerve growth factor. It has been shown that microinjection of oncogenic but not proto-oncogenic p21 protein induces morphological differentiation in PC12 cells (D. Bar-Sagi and J. R. Feramisco, Cell 42:841-848, 1985).

Parthenogenetic activation of porcine oocytes with guanosine-5'-O-(3'-thiotriphosphate). [PDF]

Biology of reproduction, 1995
A possible mechanism by which sperm activate oocytes may involve a G protein-mediated signal-transducing pathway. Artificial stimulation of G proteins leads to events very similar to those at fertilization in oocytes of several species. Here we report the effects of activation of a G protein with guanosine-5'-O-(3'-thiotriphosphate) (GTP-gamma-S), a ...

Ligand-Independent GLUT4 Translocation Induced by Guanosine 5′-O-(3-Thiotriphosphate) Involves Tyrosine Phosphorylation* [PDF]

Endocrinology, 1998
AbstractTo delineate the signaling pathway leading to glucose transport protein (GLUT4) translocation, we examined the effect of microinjection of the nonhydrolyzable GTP analog, guanosine 5′-O-(3-thiotriphosphate) (GTPγS), into 3T3-L1 adipocytes. Thirty minutes after the injection of 5 mm GTPγS, 40% of injected cells displayed surface GLUT4 staining ...

Guanosine 5′-O-(3-Thiotriphosphate) (GTPγS) Stimulation of GLUT4 Translocation is Tyrosine Kinase-dependent [PDF]

Journal of Biological Chemistry, 1998
Guanosine 5'-O-(3-thiotriphosphate) (GTPgammaS) treatment of permeabilized adipocytes results in GLUT4 translocation similar to that elicited by insulin treatment. However, although the selective phosphatidylinositol 3-kinase inhibitor, wortmannin, completely prevented insulin-stimulated GLUT4 translocation, it was without effect on GTPgammaS ...

Contribution of Active and Inactive States of the Human 5-HT4d Receptor to the Functional Activities of 5-HT4–Receptor Agonists

Journal of Pharmacological Sciences, 2008
In the present study, binding affinities of 5-hydroxytryptamine-4 (5-HT4) ligands for the human 5-HT4d receptor were determined using the agonist [3H]5-HT and the selective 5-HT4 antagonist [3H]GR113,808. We also compared the affinity differences between
