Western Blot: FXR/NR1H4 Antibody [NB400-153]

Western Blot: FXR/NR1H4 Antibody [NB400-153] - Total protein from human A549, U2OS cell and mouse 3T3 cells was separated on a 7.5% gel by SDS-PAGE, transferred to PVDF membrane and blocked in 5% non-fat milk in TBST. The membrane was probed with 2.0 ug/ml anti-FXR (NB400-153) in block buffer and detected with an anti-rabbit HRP secondary antibody using NovaLume chemiluminescence detection reagent (NPB2-61915).

Immunocytochemistry/Immunofluorescence: FXR/NR1H4 Antibody [NB400-153] - A549 cells were fixed for 10 minutes using 10% formalin and then permeabilized for 5 minutes using 1X PBS + 0.5% Triton-X100. The cells were incubated with anti-FXR/NR1H4 at 2 ug/ml overnight at 4C and detected with an anti-rabbit Dylight 488 (Green) at a 1:500 dilution. Alpha tubulin (DM1A) NB100-690 was used as a co-stain at a 1:1000 dilution and detected with an anti-mouse Dylight 550 (Red) at a 1:500 dilution. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 40X objective.

Background: FXR/NR1H4

FXR (farnesoid X receptor; NR1H4) belongs to nuclear receptor superfamily of ligand-activated transcription factors (NR1 subfamily) and acts as a receptor for bile acids such as chenodeoxycholic acid, lithocholic acid and deoxycholic acid. FXR is mainly expressed in liver, intestine, kidney, and adrenal glands. FXR heterodimerizes with retinoid X receptor (RXR alpha/NR2B1), associates with FXREs (FXR response elements) that are usually but not exclusively inverted repeat-1 (IR-1), and regulates the transcription of its target genes. FXR interacts with CARM1, SMARD1 and after activation by agonist binding, it interacts with a coactivator, NCOA1 or NCOA2. FXR has been shown to repress transcription of CYP7A1 (cholesterol 7-alpha-hydroxylase gene) through induction of NR0B2 or FGF19 expression, via two distinct mechanisms. FXR activates the intestinal bile acid-binding protein (IBABP) and transcription of bile salt export pump ABCB11 by directly recruiting histone methyltransferase CARM1 to this locus. Altogether, FXR is critical for maintaining a homeostasis in bile acid, cholesterol, lipoprotein, and triglyceride metabolism.
