(Submitter supplied) Type II nuclear hormone receptors, such as FXR, LXR, and PPAR, which function in glucose and lipid metabolism and serve as drug targets for metabolic diseases, are permanently positioned in the nucleus regardless of the ligand status. Ligand activation of these receptors is thought to occur by co-repressor/co-activator exchange, followed by initiation of transcription. However, recent genome-wide location analysis showed that LXRα and PPARα binding in the liver is largely ligand-dependent. more...

(Submitter supplied) Activation of nuclear receptors, a family of ligand-dependent transcription factors, is used extensively in development of drug targets. We have previously shown that pioneer factor Foxa2 opens chromatin for binding of nuclear receptors FXR and LXRα during acute ligand activation. FXR is activated by bile acids and deletion of Foxa2 in the liver results in intrahepatic cholestasis. We hypothesized that Foxa2 also enables chromatin conformational changes during ligand activation. more...

(Submitter supplied) The purpose of the present study was to explore in liver cells the connectivity that operates between three nuclear receptors in the liver, LXR, FXR, and PPARa, all three known to act on lipid and glucose metabolism, and also on inflammation. The human cell line HepaRG was selected for its proximity to human primary hepatocytes. Global gene expression of differentiated HepaRG cells was assessed after 4 hours and 24 hours of exposure to GW3965 (LXR agonist), GW7647 (PPARα agonist), and GW4064 and CDCA (FXR synthetic and natural agonist, respectively).

(Submitter supplied) Increasing evidence suggests that regulation of heterochromatin at the nuclear envelope underlies metabolic disease susceptibility and age-dependent metabolic changes, but the mechanism is unknown. Here we profile lamina-associated domains (LADs) using lamin B1 ChIP-Seq in young and old hepatocytes and find that, although lamin B1 resides at a large fraction of domains at both ages, a third of lamin B1-associated regions are bound exclusively at each age in vivo. more...

(Submitter supplied) Farnesoid X receptor (FXR) is a ligand activated nuclear receptor belonging to the nuclear receptor superfamily. Bile acids (BAs) are the endogenous ligand for FXR. FXR is a master regulator of BA homestasis, including BA synthesis, metabolism, transport, and enterohepatic circulation of BAs. Besides, FXR is involved in regulating diverse physioligical function in both humans and mice. GW4064 is a synthetic FXR agonist which selectively activates FXR and induce the transcription of FXR target genes.

We reported altered RNA expression profiles in primary human hepatocypes upon GW4064 treatment compared to DMSO control by RNA-seq. We also reported the altered RNA expression profiles in livers from WT C57BL/6J mice upon GW4064 treatment compared to vehicle control.

(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) The liver X receptors (LXRs) are nuclear receptors that form permissive heterodimers with retinoid X receptor (RXR) and are important regulators of lipid metabolism in the liver. We have recently shown that RXR agonist-induced hypertriglyceridemia and hepatic steatosis in mice is dependent on LXR and correlates with an LXR-dependent hepatic induction of lipogenic genes. To further investigate the role of RXR and LXR in the regulation of hepatic gene expression, we have mapped the ligand-regulated genome-wide binding of these factors in mouse liver. more...

(Submitter supplied) Aging is accompanied by physiological impairments, which, in insulin-responsive tissues, including the liver, predispose individuals to metabolic disease. However, the molecular mechanisms underlying these changes remain largely unknown. Here, we analyze genome-wide profiles of RNA and chromatin organization in the liver of young (3 months) and old (21 months) mice. Transcriptional changes suggest that de-repression of the nuclear receptors PPARα, PPARγ, and LXRα in aged mouse liver leads to activation of targets regulating lipid synthesis and storage, whereas age-dependent changes in nucleosome occupancy are associated with binding sites for both known regulators (forkhead factors and nuclear receptors) and for novel candidates associated with nuclear lamina (Hdac3 and Srf) implicated to govern metabolic function of aging liver. more...

(Submitter supplied) The nuclear receptors LXRa and LXRb play a crucial role in regulating hepatic lipid metabolism. Many genes induced in response to pharmacologic LXR agonism in mouse liver have been defined; however, the transcriptional consequences of loss of LXR binding to its genomic targets are not well characterized. Here we addressed how deletion of both LXRa and LXRb from mouse liver (LXRDKO) affects the transcriptional regulatory landscape by integrating changes in LXR/RXR binding, chromatin accessibility, and gene expression. more...
