Human G Protein-Coupled Bile Acid Receptor 1 (GPBAR1) interaction partners

1. Higher-order oligomers, likely with a tetramer organization, are formed from dimers, the smallest unit suggested for TGR5 Y111A variants.

2. Data suggest that TGR5 and FXR (show NR1H4 Proteins) in intestinal mucosa are important for glucose homeostasis, in particular in metabolic disorders such as type 2 diabetes and obesity. (TGR5 = membrane-type receptor for bile acids TGR5; FXR (show NR1H4 Proteins) = farnesoid X receptor (show xpr1 Proteins)) [REVIEW; Congress as Topic]

3. The authors conclude that taurodeoxycholic acid-induced DNA damage may depend on the activation of TGR5, CREB (show CREB1 Proteins) and NOX5 (show NOX5 Proteins)-S. It is possible that in Barrett's patients bile acids may activate NOX5 (show NOX5 Proteins)-S and increase reactive oxygen species (ROS (show ROS1 Proteins)) production via activation of TGR5 and CREB (show CREB1 Proteins). NOX5 (show NOX5 Proteins)-S-derived ROS (show ROS1 Proteins) may cause DNA damage, thereby contributing to the progression from Barrett's esophagus to esophageal adenocarcinoma.

4. GPBAR1 is expressed in advanced gastric cancers and its expression correlates with markers of epithelial-mesenchymal transition

5. TGR5 activation induces mitochondrial biogenesis and prevents renal oxidative stress and lipid accumulation, establishing a role for TGR5 in inhibiting Kidney Disease in Obesity and Diabetes Mellitus.

6. TGR5 exhibits significantly higher expression in NSCLC tumor samples and facilitates the growth and metastasis of NSCLC by activating the JAK2 (show JAK2 Proteins)/STAT3 (show STAT3 Proteins) signaling pathway.

7. TGR5 may have a role in the progression from Barrett's Esophagus to high-grade dysplasia and esophageal adenocarcinoma

8. anti-inflammation therapy targeting Gpbar1/NF-kappaB (show NFKB1 Proteins) pathway could be effective in suppressing bile acid-induced inflammation and alleviating Intrahepatic cholestasis of pregnancy-associated fetal disorders.

9. human TGR5 (hTGR5) shows higher nomilin responsiveness than does mouse TGR5.

10. bile acids promote intestinal epithelial cell proliferation and decrease mucosal injury by upregulating TGR5 expression in obstructive jaundice.

Cow (Bovine) G Protein-Coupled Bile Acid Receptor 1 (GPBAR1) interaction partners

1. TGR5 agonism induces NO production via Akt (show AKT1 Proteins) activation and intracellular Ca(2 (show CA2 Proteins)+) increase in vascular endothelial cells, and this function inhibits monocyte adhesion in response to inflammatory stimuli.

Rabbit G Protein-Coupled Bile Acid Receptor 1 (GPBAR1) interaction partners

1. TGR5 has been linked to signaling pathways involved in metabolism, cell survival, proliferation and apoptosis, which suggest a possible role of TGR5 in cancer development.

Mouse (Murine) G Protein-Coupled Bile Acid Receptor 1 (GPBAR1) interaction partners

1. G-protein coupled bile acid receptor 1 (TGR5) is required for cold-induced beiging of subcutaneous white adipose tissue (scWAT).

2. Work is the first to provide evidence for a TGR5-inhibited inflammatory response in ischemia/reperfusion injury through suppression of the TLR4 (show TLR4 Proteins)-NF-kappaB (show NFKB1 Proteins) pathway.

3. findings show GPBAR1 is essential for maintaining intestinal immune homeostasis and that its activation in the setting of inflammation reverses the immune dysfunction that occurs in rodent models of colitis

4. Data suggest that FXR (show NR1H4 Proteins) and TGR5 expression is down-regulated in aging kidney; caloric restriction prevents these age-related changes. Additionally, in long-lived Ames dwarf (show PROP1 Proteins) mice, renal FXR (show NR1H4 Proteins) and TGR5 expression is up-regulated. Treatment of aged mice with dual FXR (show NR1H4 Proteins)/TGR5 agonist reverses age-related changes in kidney structure/function. (FXR (show NR1H4 Proteins) = farnesoid X activated receptor (show NR1H4 Proteins); TGR5 = G protein-coupled bile acid receptor 1)

5. GPBAR1/TGR5 receptor agonist, tauroursodeoxycholic acid, has anti-inflammatory effects in microglial cells.

6. Vertical sleeve gastrectomy achieves its postoperative therapeutic effects through enhanced TGR5 signaling.

7. These results suggest that TGR5 contributes to the glucoregulatory benefits of vertical sleeve gastrectomy surgery by promoting metabolically favourable shifts in the circulating bile acid pool.

8. findings uncovered a novel mechanism in which INT-767 activation of FXR (show NR1H4 Proteins) induces Tgr5 gene expression and increases Ca(2 (show CA2 Proteins)+) levels and cAMP activity to stimulate GLP-1 (show GCG Proteins) secretion and improve hepatic glucose and lipid metabolism in high-fat diet-induced obese mice.

9. The results suggest that TGR5 activation mediates cross-talk between alpha- and beta-cells by switching from glucagon (show GCG Proteins) to GLP-1 (show GCG Proteins) to restore beta- cell mass and function under hyperglycemic conditions.

10. TGR5 is an important mediator of bile acid-induced cholangiocyte proliferation in vivo and in vitro. Furthermore, TGR5 protects cholangiocytes from death receptor-mediated apoptosis.
