Free fatty acids regulate gut incretin glucagon-like peptide-1 secretion through GPR120.
|
2 |
15619630
|
Gut polypeptides secreted in response to food intake, such as glucagon-like peptide-1 (GLP-1), are potent incretin hormones that enhance the glucose-dependent secretion of insulin from pancreatic beta cells.
|
3 |
15619630
|
Furthermore, we show that the stimulation of GPR120 by FFAs promotes the secretion of GLP-1 in vitro and in vivo, and increases circulating insulin.
|
4 |
15619630
|
Because GLP-1 is the most potent insulinotropic incretin, our results indicate that GPR120-mediated GLP-1 secretion induced by dietary FFAs is important in the treatment of diabetes.

Because the atypical protein kinase C (PKC), PKCzeta, is involved in FA signaling in many cells, the role of PKCzeta in FA-induced GLP-1 secretion was investigated, using the murine GLUTag L cell line and primary rat intestinal L cells.
|
14 |
17110421
|
Treatment with oleic acid (150-1000 microm) for 2 h increased GLP-1 secretion (P < 0.001), and this was abrogated by the PKCzeta inhibitor ZI (P < 0.05) and PKCzeta small interfering RNA transfection (P < 0.05) but not inhibition of classical/novel PKC isoforms.
|
15 |
17110421
|
GLUTag cells expressed mRNA for the Gq-coupled FA receptor GPR120; however, oleic acid did not induce any changes in Akt, MAPK, or calcium, and pretreatment with LY294002 and PD98059 to inhibit phosphatidylinositol 3-kinase and MAPK, respectively, did not prevent the effects of oleic acid.
|
16 |
17110421
|
These findings demonstrate that PKCzeta is required for oleic acid-induced GLP-1 secretion.

Several GPCRs are involved in metabolic regulation and glucose homeostasis such as GLP-1 receptor, glucagon receptor, adiponectin receptor and so on.

|
GPR40 and GPR120 are activated by medium and long-chain FFAs, whereas GPR41 and GPR43 can be activated by short-chain FFAs.
|
19 |
17465724
|
GPR40, which is preferentially expressed in pancreatic beta-cells, mediates the majority of the effects of FFAs on insulin secretion.
|
20 |
19817784
|
It has since been shown that GPR40 contributes to FA amplification of glucose-induced insulin secretion.
|
21 |
19817784
|
GPR119 is expressed in pancreatic beta-cells and enteroendocrine L-cells, and augments circulating insulin levels both through its direct insulinotropic action on beta-cells and through FA stimulation of glucagon-like peptide 1 (GLP-1) secretion.
|
22 |
19817784
|
GPR120 is expressed in L-cells and was also shown to mediate FA-stimulated GLP-1 release.
|
23 |
19817784
|
Finally, GPR41 and GPR43 are receptors for short-chain FAs and may indirectly regulate beta-cell function via adipokine secretion.
|

|
In addition to GIP, K-cells secrete xenin, a peptide with as of yet poorly understood physiological functions, and GIP is often colocalized with the other incretin hormone glucagon-like peptide-1 (GLP-1).
|
25 |
21094898
|
Its secretion is elicited by intraluminal nutrients, especially carbohydrate and fat, through the action of SGLT1, GPR40, GPR120, and GPR119.
|
26 |
21094898
|
Intracellular signaling mechanisms of GIP secretion are still elusive but include activation of adenylyl cyclase, protein kinase A (PKA), and protein kinase C (PKC).
|
27 |
21094899
|
This has led to the hypothesis that these receptors may act as sensors of food intake modulating, for example, release of incretin hormones from the gut, insulin/glucagon from the pancreas, and leptin from adipose tissue.
|

In the present review, we describe the molecular mechanisms of nutrient-sensing of the calcium-sensing receptor (CaR), the G protein-coupled receptor family C, group 6, subtype A (GPRC6A), and the taste1 receptor T1R1/T1R3-sensing L-α-amino acids; the carbohydrate-sensing T1R2/T1R3 receptor; the proteolytic degradation product sensor GPR93 (also termed GPR92); and the FFA sensing receptors FFA1, FFA2, FFA3, GPR84, and GPR120.

Proglucagon is cleaved to glucagon by prohormone convertase 2 (PC2) in pancreatic α-cells, but is cleaved to glucagon-like peptide-1 (GLP-1) by PC1 in intestinal L-cells.
|
55 |
21795304
|
The aim of this study was to identify mechanisms which switch processing of proglucagon to generate GLP-1 in the pancreas, given that GLP-1 can increase insulin secretion and β-cell mass.
|
56 |
21795304
|
The α-cell line, αTC1-6, expressed PC1 at low levels and GLP-1 was detected in cells and in culture media.
|
57 |
21795304
|
Three G protein-coupled receptors, GPR120, TGR5 and GPR119, implicated in the release of GLP-1 from L-cells are expressed in αTC1-6 cells.
|
58 |
21795304
|
Incubation of these cells with an agonist of TGR5 increased PC1 promoter activity and GLP-1 secretion suggesting that this is a mechanism for switching processing to GLP-1 in the pancreas.

Discovery of G protein coupled receptors for long chain free fatty acids (FFAs), FFA1 (GPR40) and GPR120, has expanded our understanding of these nutrients as signaling molecules.
|
69 |
22649399

|
79 |
22678998
|
Meal-induced increase in gastric mucosal LCFA was assessed by measuring the transcripts of markers for tissue uptake of LCFA, lipoprotein lipase (LPL), fatty acid translocase (CD36), glycosylphosphatidylinositol-anchored HDL-binding protein 1, and nuclear fatty acid receptor peroxisome proliferator-activated receptor-γ.

Short-chain free fatty acid receptors FFA2/GPR43 and FFA3/GPR41 as new potential therapeutic targets.

23060857
|
The deorphanization of the free fatty acid (FFA) receptors FFA1 (GPR40), FFA2 (GPR43), FFA3 (GPR41), GPR84, and GPR120 has made clear that the body is capable of recognizing and responding directly to nonesterified fatty acid of virtually any chain length.

HHcy activated c-Jun N-terminal kinase (JNK), the downstream signal of ER stress in adipose tissue, and activated JNK participated in insulin resistance by inhibiting Akt activation.
|
95 |
23417716
|
Furthermore, JNK activated c-Jun and p65, which in turn triggered the transcription of proinflammatory cytokines.
|
96 |
23417716
|
Chemical chaperones PBA and TUDCA could reverse Hcy-induced inflammation and restore insulin-stimulated glucose uptake and Akt activation.
|
97 |
23417716
|
Activation of GPR120 reversed Hcy-induced JNK activation and prevented inflammation but not ER stress.
|
98 |
23417716
|
Therefore, HHcy inhibited insulin sensitivity in adipose tissue by inducing ER stress, activating JNK to promote proinflammatory cytokine production and facilitating macrophage infiltration.
