Research Backgrounds

Function:

G protein-coupled receptor that is activated by a major product of dietary fiber digestion, the short chain fatty acids (SCFAs), and that plays a role in the regulation of whole-body energy homeostasis and in intestinal immunity. In omnivorous mammals, the short chain fatty acids acetate, propionate and butyrate are produced primarily by the gut microbiome that metabolizes dietary fibers. SCFAs serve as a source of energy but also act as signaling molecules. That G protein-coupled receptor is probably coupled to the pertussis toxin-sensitive, G(i/o)-alpha family of G proteins but also to the Gq family. Its activation results in the formation of inositol 1,4,5-trisphosphate, the mobilization of intracellular calcium, the phosphorylation of the MAPK3/ERK1 and MAPK1/ERK2 kinases and the inhibition of intracellular cAMP accumulation. May play a role in glucose homeostasis by regulating the secretion of GLP-1, in response to short-chain fatty acids accumulating in the intestine. May also regulate the production of LEP/Leptin, a hormone acting on the central nervous system to inhibit food intake. Finally, may also regulate whole-body energy homeostasis through adipogenesis regulating both differentiation and lipid storage of adipocytes. In parallel to its role in energy homeostasis, may also mediate the activation of the inflammatory and immune responses by SCFA in the intestine, regulating the rapid production of chemokines and cytokines. May also play a role in the resolution of the inflammatory response and control chemotaxis in neutrophils. In addition to SCFAs, may also be activated by the extracellular lectin FCN1 in a process leading to activation of monocytes and inducing the secretion of interleukin-8/IL-8 in response to the presence of microbes. Among SCFAs, the fatty acids containing less than 6 carbons, the most potent activators are probably acetate, propionate and butyrate. Exhibits a SCFA-independent constitutive G protein-coupled receptor activity.

Figure 5. Isobutyric acid regulated G protein-coupled receptor (GPCR) expression and histone acetyltransferase (HAT) activity. For the expression of GPCRs, the results of RT-qPCR (A), Western blot (B), and immunocytochemical staining (C) showed that GPR41, GPR43, and GPRC5A expressions were significantly higher, while PAR1 expression was significantly lower in isobutyric acid treatment group (1.85 mM) than the control groups (control and NC). Immunofluorescence staining (D) identified the expression location of GPCRs. For the expression of acetyl-histones and histones, the results of Western blot (E) and immunocytochemical staining (F) showed that acetyl-histone H3 and H4 expressions were significantly higher in the isobutyric acid treatment group (1.85 mM) than the control groups (control and NC), whereas Western blot results showed that there was no significant difference of the expression of histone H3 and H4 between isobutyric acid treatment group and the control groups. Immunofluorescence staining (G) identified the expression location of acetyl-histone H3 and H4. HAT activity assay (H) results showed that HAT activity was increased in the isobutyric acid treatment group (1.85mM) than in the control groups (control and NC). P-values were calculated using Student's t-tests. ns: no significance; *p < 0.05; **p < 0.01; ***p < 0.001. All experiments were repeated three times. NC, negative control (0mM).
