This study provides some data suggesting the possible involvement of FXR in the pathophysiology and development of thyroid neoplasms. In particular, we found that there are differences regarding FXR expression between papillary carcinomas and hyperplastic nodules, being also correlated with some patients' clinicopathological parameters.
Data suggest that TGR5 (zeige GPBAR1 Proteine) and FXR in intestinal mucosa are important for glucose homeostasis, in particular in metabolic disorders such as type 2 diabetes and obesity. (TGR5 (zeige GPBAR1 Proteine) = membrane-type receptor for bile acids TGR5 (zeige GPBAR1 Proteine); FXR = farnesoid X receptor (zeige xpr1 Proteine)) [REVIEW; Congress as Topic]
These results suggested that FXR may serve as an important negative regulator for manipulating Smad3 (zeige SMAD3 Proteine) expression, and the FXR/Smad3 (zeige SMAD3 Proteine) pathway may be a novel target for the treatment of renal fibros
Loss of FXR or its down-regulation is associated with higher bile acids concentrations and with a pro-tumorigenic phenotype. (Review)
Lys (zeige LYZ Proteine)-325 is a non-canonical site of SUMOylation of human FXR.CK2 is the priming effector that phosphorylates Ser (zeige SIGLEC1 Proteine)-327, resulting in enhanced SUMO2 (zeige SUMO2 Proteine) conjugation, which then directs the ubiquitination and degradation of FXR through the recruitment of the SUMO-dependent ubiquitin E3 ligase RNF4 (zeige RNF4 Proteine).
we proposed a model to link FXR to Sp1 (zeige PSG1 Proteine), which included triggered FXR, p38/MAPK (zeige MAPK14 Proteine) and/or PI3K (zeige PIK3CA Proteine)/AKT (zeige AKT1 Proteine) signaling and phosphorylated Sp1 (zeige PSG1 Proteine), to illustrate the potential crosstalk between the two factors.
the presented evidence suggested that WA can inhibit HCC (zeige FAM126A Proteine) cell proliferationand tumorigenesis through miR (zeige MLXIP Proteine)-22-repressed CCNA2 (zeige CCNA2 Proteine), which was at least partially through FXR regulation
The results indicated that epigenetically regulated miR (zeige MLXIP Proteine)-449a targets CREB5 (zeige CREB5 Proteine) to increase FXRalpha expression, thereby promoting HBV replication and gene expression. Our findings provide a new understanding of the role of miRNAs in HBV replication
In diabetic humans, there is decreased FXR expression in the kidney. FXR plays an important role in Diabetic Kidney Disease.
FXR regulates serum triglyceride level in part through PLA2G12B (zeige PLA2G12B Proteine).
results suggest that hypothyroidism induces a moderate non-alcoholic steatohepatitis, alllowing the hepatic regeneration. The FXRalpha may be involved in the development of non-alcoholic steatohepatitis in hypothyroid subjects.
FXR is expressed in the ovary, in all regions of the oviduct, and all portions of the vagina of rabbits.
FXR exerts its function in L cells through interacting with CREB (zeige CREB1 Proteine), a crucial transcriptional regulator of cAMP-CREB (zeige CREB1 Proteine) signaling pathway, to inhibit its transcriptional activity. Targeting FXR to rescue GLP-1 (zeige GCG Proteine) secretion may be a promising strategy for type II diabetes.
The underlying mechanism of curcumin against cholestasis was restoring bile acid homeostasis and antagonizing inflammatory responses in a FXR-dependent manner and in turn contributed to overall cholestasis attenuation.
FXR alpha helps establish and maintain an undifferentiated germ cell pool and in turn influences male fertility. FXR alpha controls the expression of the pluripotency marker Lin28 (zeige LIN28A Proteine) in the germ cells.
FXR signaling is a bile acid nuclear receptor that regulates lipids and glucose homeostasis and lack of it causes hepatomegaly and liver dysfunction.
These results suggest that lack of FXR impaired FoxO3a (zeige FOXO3 Proteine)-mediated autophagy and in turn exacerbated alcohol-induced liver injury
Bile acids and salts (BA) treatment-farnesoid X-activated receptor (FRXalpha) signaling is a critical actor during sexual maturation.
The study shows that FXR/RXR regulates Chop (zeige DDIT3 Proteine) expression in a mouse model of steatohepatitis, providing novel insights into pathogenesis of this disorder.
FXR activation ameliorated central nervous system autoimmunity in an IL-10 (zeige IL10 Proteine)-dependent fashion and even suppressed advanced clinical disease upon therapeutic administration
In livers of mice, FXR regulates amino acid catabolism and detoxification of ammonium via ureagenesis and glutamine synthesis.
alterations in bile acid composition may have contributed to the observed disturbance in FXR-mediated signalling pathways in short bowel syndrome-associated liver disease
FXR splice variant has a dominant positive effect on wild type FXR.
In conclusion, PXR (zeige NR1I2 Proteine) and FXR both responded to ligands that activated their human orthologs, and some of the alternatively spliced variants significantly altered PXR (zeige NR1I2 Proteine) and FXR transactivation at in vivo expression levels.
This gene encodes a ligand-activated transcription factor, which shares structural features in common with nuclear hormone receptor family, such as a DNA-binding domain that targets the receptor to specific DNA sequences, and a ligand-binding domain, which interacts directly with the ligand and contains a ligand-dependent transcriptional activation domain. This protein functions as a receptor for bile acids, and when bound to bile acids, regulates the expression of genes involved in bile acid synthesis and transport. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.
