  • AS1269574 stimulates GLP-1 release and increases [Ca2+]i in STC-1 cells. A, AS1269574 (AS) exerted a dose-dependent action to stimulate the release of immunoreactive GLP-1 from STC-1 cells in static incubation assays. Data are averaged from five independent assays *, P < .02 (paired t test; see Materials and Methods for experimental details). B, AS1269574 but not the control vehicle solution containing 0.1% dimethylsulfoxide (vehicle) exerted a dose-dependent action to increase [Ca2+]i in fura-2 loaded STC-1 cell monolayers. A vertical arrow indicates when the test solutions were administered to individual wells of a 96-well plate, here and in all subsequent figures. Concentrations of test substances are the final concentrations present in the individual wells after injection of the test solutions, here and in all subsequent figures. C, The maximal increase of [Ca2+]i for a range of AS1269574 concentrations, as derived from the raw data presented in panel B. D, AS1269574 (AS; 30 μM) stimulated oscillations of [Ca2+]i in a single fura-2 loaded STC-1 cell. The horizontal bar indicates the time course during which AS1269574 was administered via a micropipette positioned immediately adjacent to the cell. B–D, For all examples depicted here, the findings are representative of a single experiment that was repeated a minimum of five times on five different occasions with similar results. E1–E3, Pseudocolor radiometric images of fura-2 fluorescence in clusters of STC-1 cells in which blue represents a low [Ca2+]I; green-yellow indicates an intermediate [Ca2+]i, and red indicates a high [Ca2+]i. Panels in E1–E3 indicate levels of [Ca2+]i before, during, and after application of AS1269574 (100 μM). These individual images were derived from the accompanying Supplemental Movie.[2].

  • GPR119-independent actions of AS1269574 to increase [Ca2+]i but not cAMP in STC-1 cell monolayers. A, GPR119 agonists AR231453 (AR; 6 μM), and OEA (30 μM) failed to increase [Ca2+]i, whereas AS1269574 (AS; 100 μM) did so. B, GPR119 antagonist TM43718 failed to significantly alter the action of AS1269574 to increase [Ca2+]i. C, AR231453 (1 μM) failed to increase [Ca2+]i under standard assay conditions (AR 1), whereas AS1269574 (AS; 100 μM) did so. Pretreatment with AR231453 (1 μM) for 15 minutes (AR pre, AS) failed to alter the subsequent action of AS1269574 (100 μM). D, A two-step injection mode assay revealed that combined administration of forskolin (F; 2 μM) and IBMX (I; 100 μM) failed to increase [Ca2+]i (FI, arrow 1, black trace), nor did the SES vehicle solution have any subsequent effect (SES, arrow 2, black trace). In the absence of forskolin, an initial injection of SES vehicle solution was without effect (SES, arrow 1, blue trace), whereas AS1269574 (100 μM) stimulated an increase of [Ca2+]i (AS 100, arrow 2, blue trace). When forskolin and IBMX were administered together during the initial injection (FI, arrow 1, red trace), there was no increase of [Ca2+]i, and the subsequent action of AS1269574 (AS 100, arrow 2, red trace) was not modified. E and F, AS1269574 (30 or 100 μM) failed to raise levels of cAMP, as inferred from its failure to induce an increase of the 535:484 nm AKAR3 FRET ratio (E). However, an increase of the 534:484 nm AKAR3 FRET ratio was measured in response to the positive control test solution containing forskolin (Fsk; 2 μM) and IBMX (100 μM). A–F, For all examples depicted here, the findings are representative of a single experiment that was repeated a minimum of three times on three different occasions with similar results.[2].

  • AS1269574 and AITC activate inward currents to increase [Ca2+]i in STC-1 cells. A, AS1269574 (AS 100) was applied at a concentration of 100 μM for 5 seconds directly to a single STC-1 cell (vertical arrows). The experiment was performed under conditions of whole-cell voltage clamp (−60 mV pipette holding potential) in which the cell was loaded with fura-2. AS1269574 activated an inward membrane current (A1), the time course of which closely matched the accompanying increase of [Ca2+]i (A2) in the same cell. Nearly identical findings were obtained in three separate experiments using a total of 10 cells. B, To determine the I-V relationship of the membrane current activated by AS1269574, the pipette potential was shifted as a voltage ramp from −70 mV to +70 mV (1 Vs−1). The baseline ramp current measured in the absence of AS1269574 was subtracted from the ramp current measured in the presence of AS1269574 so that the difference current could be calculated. The difference current is plotted as a function of the pipette potential in order to obtain the I-V relationship that indicates outward rectification characteristic of TRPA1 channels. For the illustrated cell, the reversal potential for the ramp current was +9 mV. For a total of 12 cells studied, the mean value of the reversal potential was +4 ± 2 mV (n = 12). C, RT-PCR detection of GPR119 and TRPA1 mRNA in STC-1 cells (reverse transcriptase [RT]). D, Representative example of the membrane current activated by a 5-second application of AITC (100 μM) to an STC-1 cell using methods described for panel A, above. Nearly identical findings were obtained in two separate experiments using a total of eight cells. E, Representative example of the I-V relationship for the membrane current activated by AITC. Note the close correspondence of this I-V relationship to that of panel B for AS1269574. For the illustrated cell, the reversal potential for the ramp current was +10 mV. For a total of 12 cells studied, the mean value of the reversal potential was +11 ± 2 mV (n = 12).[2]. GPR119 Agonist AS1269574 Activates TRPA1 Cation Channels to Stimulate GLP-1 Secretion.
