Free fatty acids regulate insulin secretion from pancreatic β cells through GPR40
Diabetes, a disease in which carbohydrate and lipid metabolism are regulated improperly by insulin, is a serious worldwide health issue. Insulin is secreted from pancreatic β cells in response toExpand

A New Peptidic Ligand and Its Receptor Regulating Adrenal Function in Rats*
We searched for peptidic ligands for orphan G protein-coupled receptors utilizing a human genome data base and identified a new gene encoding a preproprotein that could generate a peptide. ThisExpand

Feeding status and serotonin rapidly and reversibly modulate a Caenorhabditis elegans chemosensory circuit.
Serotonin (5-HT) modulates synaptic efficacy in the nervous system of vertebrates and invertebrates. In the nematode Caenorhabditis elegans, many behaviors are regulated by 5-HT levels, which are inExpand

Mutations in a Cyclic Nucleotide–Gated Channel Lead to Abnormal Thermosensation and Chemosensation in C. elegans
The C. elegans tax-4 mutants are abnormal in multiple sensory behaviors: they fail to respond to temperature or to water-soluble or volatile chemical attractants. We show that the predicted tax-4Expand

Identification of a G Protein-coupled Receptor Specifically Responsive to β-Alanine*
We isolated a cDNA encoding an orphan G protein-coupled receptor, TGR7, which has been recently reported to correspond to MrgD. To search for ligands for TGR7, we screened a series of small moleculeExpand

OSM-11 Facilitates LIN-12 Notch Signaling during Caenorhabditis elegans Vulval Development
Notch signaling is critical for cell fate decisions during development. Caenorhabditis elegans and vertebrate Notch ligands are more diverse than classical Drosophila Notch ligands, suggestingExpand

C. elegans Notch Signaling Regulates Adult Chemosensory Response and Larval Molting Quiescence
BACKGROUND The conserved DOS-motif proteins OSM-7 and OSM-11 function as coligands with canonical DSL (Delta, Serrate, and LAG-2) ligands to activate C. elegans Notch receptors during development. WeExpand

A Novel Antidiabetic Drug, Fasiglifam/TAK-875, Acts as an Ago-Allosteric Modulator of FFAR1
Selective free fatty acid receptor 1 (FFAR1)/GPR40 agonist fasiglifam (TAK-875), an antidiabetic drug under phase 3 development, potentiates insulin secretion in a glucose-dependent manner byExpand

Anatomical Transcriptome of G Protein-Coupled Receptors Leads to the Identification of a Novel Therapeutic Candidate GPR52 for Psychiatric Disorders
Many drugs of abuse and most neuropharmacological agents regulate G protein-coupled receptors (GPCRs) in the central nervous system (CNS)_ENREF_1. The striatum, in which dopamine D1 and D2 receptorsExpand

Functional reconstitution of a heteromeric cyclic nucleotide-gated channel of Caenorhabditis elegans in cultured cells
The tax-4 and tax-2 genes of Caenorhabditis elegans are essential for normal olfaction, gustation, and thermosensation, suggesting that they have a role in sensory transduction. The predictedExpand
