Rodent (Mouse/Rat) Peroxisome Proliferator-Activated Receptor Gamma (mrPPARγ; nr1c3)
Also available in: Human
INDIGO’s Mouse/Rat PPAR gamma (mrpparγ; nr1c3) Assay utilizes proprietary non-human mammalian cells engineered to provide high-level expression of mrPPARγ. Reporter Cells also incorporate an mrPPARγ-responsive luciferase reporter gene, therefore, quantifying expressed luciferase activity provides a sensitive surrogate measure of mrPPARγ activity in the treated cells. The principle application of this reporter assay system is in the screening of test samples to quantify any functional activity, either agonist or antagonist, that they may exert against mrPPARγ.
Peroxisome proliferator-activated receptor gamma (PPAR-gamma or PPARγ), also known as the glitazone receptor, or NR1C3 (nuclear receptor subfamily 1, group C, member 3) is a type II nuclear receptor that in humans is encoded by the PPARG gene. PPARs form heterodimers with retinoid X receptors (RXRs) and these heterodimers regulate transcription of various genes. PPARγ regulates adipocyte differentiation, fatty acid storage and glucose metabolism. The PPARγ knockout mice fail to generate adipose tissue when fed a high fat diet. Many insulin sensitizing drugs used in the treatment of diabetes target PPARγ as a means to lower serum glucose without increasing pancreatic insulin secretion. Additionally, PPARγ has been implicated in the pathology of numerous diseases including obesity, diabetes, atherosclerosis and cancer. Alternatively spliced transcript variants that encode different isoforms have been described.

mrPPARγ Reporter Cells are prepared using INDIGO’s proprietary CryoMite™ process. This cryo-preservation method yields exceptional cell viability post-thaw, and provides the convenience of immediately dispensing healthy, division-competent reporter cells into assay plates. There is no need for cumbersome intermediate treatment steps such as spin-and-rinse of cells, viability determinations, or cell titer adjustments prior to assay setup.
INDIGO Bioscience’s Nuclear Receptor Reporter Assays are all-inclusive cell-based assay systems. In addition to mrPPARγ Reporter Cells, this kit provides two optimized media for use during cell culture and in diluting the user’s test samples, a reference agonist, Luciferase Detection Reagent, and a cell culture-ready assay plate.

GPR40 partial agonist MK-2305 lower fasting glucose in the Goto Kakizaki rat via suppression of endogenous glucose production
ABSTRACT GPR40 (FFA1) is a fatty acid receptor whose activation results in potent glucose lowering and insulinotropic effects in vivo. Several reports illustrate that GPR40 agonists exert glucose lowering in diabetic humans. To assess the mechanisms by which GPR40 partial agonists improve glucose homeostasis, we evaluated the effects of MK-2305, a potent and selective partial
Structural basis for differential activities of enantiomeric PPARγ agonists: Binding of S35 to the alternative site
ABSTRACT Peroxisome proliferator-activated receptor γ (PPARγ) is a member of the nuclear receptor superfamily. It functions as a ligand-activated transcription factor and plays important roles in the regulation of adipocyte differentiation, type 2 diabetes mellitus, and inflammation. Many PPARγ agonists bind to the canonical ligand-binding pocket near the activation function-2 (AF-2) helix (i.e., helix H12)
ABSTRACT Focal adipose deficiency, such as lipoatrophy, lumpectomy or facial trauma, is a formidable challenge in reconstructive medicine, and yet scarcely investigated in experimental studies. Here, we report that Pyrintegrin (Ptn), a 2,4-disubstituted pyrimidine known to promote embryonic stem cells survival, is robustly adipogenic and induces postnatal adipose tissue formation in vivo of transplanted adipose
Lesinurad, a novel, oral compound for gout, acts to decrease serum uric acid through inhibition of urate transporters in the kidney
ABSTRACT Background Excess body burden of uric acid promotes gout. Diminished renal clearance of uric acid causes hyperuricemia in most patients with gout, and the renal urate transporter (URAT)1 is important for regulation of serum uric acid (sUA) levels. The URAT1 inhibitors probenecid and benzbromarone are used as gout therapies; however, their use is limited
Leoligin, the major lignan from edelweiss, inhibits 3-hydroxy-3-methyl-glutaryl-CoA reductase and reduces cholesterol levels in ApoE −/− mice
ABSTRACT The health benefit through the control of lipid levels in hyperlipidaemic individuals is evident from a large number of studies. The pharmacological options to achieve this goal shall be as specific and personalized as the reasons for and co-factors of hyperlipidaemia. It was the goal of this study to reveal the impact of leoligin
Anti-diabetic effect of 3-hydroxy-2-naphtoic acid, an endoplasmic retiulum stress-reducing chemical chaperone
ABSTRACT Lots of experimental and clinical evidences indicate that chronic exposure to saturated fatty acids and high level of glucose is implicated in insulin resistance, beta cell failure and ultimately type 2 diabetes. In this study, we set up cell-based experimental conditions to induce endoplasmic reticulum (ER) stress and insulin resistance using high concentration of
Design, synthesis, and biological evaluation of novel thiazolidinediones as PPARγ/FFAR1 dual agonists
ABSTRACT Diabetes mellitus is a chronic metabolic disorder that affects more than 180 million people worldwide. Peroxisome proliferator activated receptors (PPARs) are a group of nuclear receptors that have been targeted by the thiazolidinedione (TZD) class of compounds for the management of type II diabetes. PPARγ is known to regulate adipogenesis and glucose metabolism. Another
Systems toxicology identifies mechanistic impacts of 2-amino-4,6-dinitrotoluene (2A-DNT) exposure in Northern Bobwhite
ABSTRACT Background: A systems toxicology investigation comparing and integrating transcriptomic and proteomic results was conducted to develop holistic effects characterizations for the wildlife bird model, Northern bobwhite (Colinus virginianus) dosed with the explosives degradation product 2-amino-4,6-dinitrotoluene (2A-DNT). A subchronic 60d toxicology bioassay was leveraged where both sexes were dosed via daily gavage with 0, 3, 14, or 30 mg/kg-d

SIG1191 dose-response analysis of the human PPARγ (ligand-dependent transcription factor) activity was performed using INDIGO Biosciences’ luciferase reporter cells and compared to rosiglitasone as reference agonist ligand. ABSTRACT Isoprenylcysteine compounds that modulate the intracellular signal transduction activity of Gproteins have been shown to regulate the in vitro responses of inflammatory cells. Topical in vivo anti-inflammatory
Keratinocyte differentiation and upregulation of ceramide synthesis induced by an oat lipid extract via the activation of PPAR pathways
ABSTRACT Activation of peroxisome proliferator-activated receptors (PPARs) has been shown to have an important role in skin barrier function by regulating differentiation and lipid synthesis in keratinocytes. Oat (Avena sativa) has long been used as a soothing agent to relieve skin irritations, and the clinical benefits of topical oat formulations have been proven; however, the
