(Submitter supplied) Farnesoid-X-Receptor (FXR) plays a central role in maintaining bile acid (BA) homeostasis by transcriptional control of numerous enterohepatic genes, including intestinal FGF19, a hormone that strongly represses hepatic BA synthesis. How activation of the FGF19 receptor at the membrane is transmitted to the nucleus for transcriptional regulation of BA levels and whether FGF19 signaling posttranslationally modulates function of FXR remain largely unknown. more...

(Submitter supplied) ABSTRACT Background & aims: The role of the intestine in the maintenance of cholesterol homeostasis is increasingly recognized. Fecal excretion of cholesterol is the last step in the atheroprotective reverse cholesterol transport (RCT) pathway, to which both biliary and transintestinal cholesterol excretion (TICE) contribute. The mechanisms controlling the flux of cholesterol through the TICE pathway are,however, poorly understood. more...

(Submitter supplied) Small Heterodimer Partner (SHP/NR0B2) is an unusual orphan nuclear receptor that does not have a DNA binding domain and acts as a co-repressor for many transcriptional factors, including LRH-1, SREBPs, FOXA1, and AhR, which inhibits expression of its target genes. To explore global intestinal functions of SHP, WT and SHP-KO mice were fed for 6 h after fasting overnight. In SHP-KO mice, 1,707 genes were upregulated, and 1,055 genes downregulated by 2-fold or more compared to WT mice. more...

(Submitter supplied) Unfiltered coffee markedly increases serum lipid levels in humans and mice. The responsible compounds are the fat-soluble diterpenes cafestol and kahweol. Cafestol is responsible for more than 80% of the effect on serum lipids and is the most potent cholesterol-elevating compound known in the human diet. Aim of these microarray studies was to identify novel genes and regulatory pathways determining the cholesterol raising effect of cafestol by genome-wide expression studies. more...

(Submitter supplied) Glucagon, an essential regulator of glucose and lipid metabolism, also promotes weight loss, in part through potentiation of fibroblast-growth factor 21 (FGF21) secretion. However, FGF21 is only a partial mediator of metabolic actions ensuing from GcgR-activation, prompting us to search for additional pathways. Intriguingly, chronic GcgR agonism increases plasma bile acid levels. We hypothesized that GcgR agonism regulates energy metabolism, at least in part, through farnesoid X receptor (FXR). more...

(Submitter supplied) Background: Fibroblast growth factor-19 (FGF19) is an intestinal hormone that mediates postprandial metabolic responses in the liver. The unusual orphan nuclear receptor, Small Heterodimer Partner (SHP), acts as a co-repressor for many transcriptional factors and has been implicated in diverse biological pathways including FGF19-mediated repression of bile acid synthesis. To explore global functions of SHP in mediating FGF19 action, we identify genome-wide SHP binding sites in hepatic chromatin in mice treated with vehicle or FGF19 by ChIP-seq analysis. more...

(Submitter supplied) Administration of FGF19 - a physiological regulator of bile acid homeostasis - to diabetic and diet-induced-obese mice can suppress plasma glucose concentration and improve insulin sensitivity. Repurposing FGF19 as a therapeutic agent for treating type 2 diabetes and cholestatic liver disease is therefore of significant interest. However, the tumorigenic risk associated with prolonged FGF19 administration is a major hurdle in realizing its full clinical potential. more...

(Submitter supplied) We isolated whole livers from male TDG knockout livers (4-month post tamoxifen injection) and HCC, along with their age matched male control livers. RNA was extracted from the samples as per RNAzol manufacturer guidelines with DNase treatment. RNA was then analyzed by bioanalyzer and subjected to sequencing using the Illumina NextSeq 500 platform.
