  • (C) Indicated macrophages were treated with LPS (100 ng/mL) in the absence or presence of GKT137831 (1 μmol/L) for 24 h. PKM2 mRNA and lactate levels were assayed (n = 3, *, p < 0.05 versus LPS group).

  • Serum markers of liver injury and liver pathology in mice fed control (Ctrl) or ethanol (EtOH) for four weeks with or without GKT137831 for the last two weeks. (A) Light microscopy with hematoxylin & eosin staining shows accumulation of lipid droplets (arrows) and necrosis (arrowheads) in the liver of ethanol-fed mice, which was attenuated by GKT137831 treatment. (B) Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities. Serum ALT and AST activities were measured by using Infinity ALT and AST Reagents. Scale bar: 20μM. Results are mean ± SD (n=6). Results for bars that do not share a letter differed significantly among groups (P <0.05). Significant differences among groups are determined by ANOVA followed by Tukey’s test.

  • A549 cells were treated with GKT137831 (20 µM) or NAC (25 µM) after transfection with NOX4 plasmid for 48 h. Nrf2 expression was analyzed by western blotting (B). NOX4-overexpressed A549 cells were pretreated with MG132 (25 µM) after the addition of NAC or GKT137831 (C).

  • AGE3-BSA-induced apoptosis in A7r5 cells was mediated by NAD(P)H oxidase. (a) Cultured A7r5 cells were incubated in calcification medium containing cBSA, or AGE3-BSA (100 µg/mL) in the presence or absence of NAD(P)H oxidase inhibitors including GKT137831 (20 µM) or VAS2870 (10 µM) for three days. Apoptosis was evaluated by TUNEL assay, as described in the Method section. Cells in the culture were identified by nuclear staining with Hoechst, and evaluated under a fluorescence microscope; (b) For quantification, Hoechst and TUNEL double positive cells were counted in 10 random microscopic fields at 200× magnification, and expressed as percent TUNEL positive cells in a culture. Statistical significance of the results was analyzed by one-way ANOVA followed by LDS post-hoc test. Statistical significance was denoted as follows, ** p < 0.001 vs. AGE3-BSA.

GKT137831 attenuates hypoxia-induced H(2)O(2) release, cell proliferation, and TGF-β1 expression and blunted reductions in PPARγ in HPAECs and HPASMCs. [2] GKT137831 also prevents oxidative stress in response to hyperglycemia in human aortic endothelial cells. [3]

In vivo In WT and SOD1mut mice, GKT137831 (60 mg/kg i.g.) blocks liver fibrosis and downregulates markers of oxidative stress, inflammation, and fibrosis. [1] GKT137831 (60 mg/kg/d p.o.) also attenuates chronic hypoxia–induced right ventricular hypertrophy, vascular remodeling, lung cell proliferation, and hypoxic alterations in lung PPARγ and TGF-β1 expression in mouse model of chronic hypoxia exposure. [2] In diabetic apolipoprotein E-deficient mice, GKT137831 (60 mg/kg/d p.o.) attenuates diabetes mellitus-accelerated atherosclerosis. [3] Moreover, in angII-infused c-hNox4Tg mice, GKT137831 abolishes the increase in oxidative stress, suppresses Akt-mTOR and NF-κB signaling pathway and attenuates cardiac remodeling. [4]


Cell Research:


- Collapse
  • Cell lines: Hypoxic HPASMC and HPAECs
  • Concentrations: 20 μM
  • Incubation Time: 72 hours
  • Method:

    Hypoxic HPASMC and HPAEC proliferation is determined using MTT assay, by Western blotting to detect proliferating cell nuclear antigen (PCNA) expression, or by manual cell counting after Trypan blue staining. Amplex Red Hydrogen Peroxide/Peroxidase Assay Kit is used to measure H2O2 released into the culture media from HPAECs or HPASMCs. After exposure to control or hypoxic environments for 72 hours, Amplex Red reagent is added, and the cells are returned to control or hypoxic environments for an additional hour before fluorescence measurements.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
