Corn silk induces nitric oxide synthase in murine macrophages

Kim KA, Choi SK, Choi HS

  • KMID: 1103321
  • Exp Mol Med.
  • 2004 Dec;36(6):545-550.
Corn silk has been purified as an anticoagulant previously and the active component is a polysaccharide with a molecular mass of 135 kDa. It activates murine macrophages to induce nitric...

Cobalt Chloride Attenuates Oxidative Stress and Inflammation through NF-kappaB Inhibition in Human Renal Proximal Tubular Epithelial Cells

Oh SW, Lee YM, Kim S, Chin HJ, Chae DW, Na KY

We evaluated the effect of cobalt chloride (CoCl2) on TNF-alpha and IFN-gamma-induced-inflammation and reactive oxygen species (ROS) in renal tubular epithelial cells (HK-2 cells). We treated HK-2 cells with CoCl2...

NF-kappaB Binding Activity and Cyclooxygenase-2 Expression in Persistent betaCCI(4)-Treated Rat Liver Injury

Kim SH, Chu HJ, Kang DH, Song GA, Cho M, Yang US, Kim HJ, Chung HY

The involvement of NF-kappaB binding activity is known to be important in the mechanism of acute liver injury and in the induction of cyclooxygenase (COX-2). This study was performed to...

Epigallocatechin-3-gallate Suppresses Galactose-alpha1,4-galactose-beta1,4-glucose Ceramide Expression in TNF-alpha Stimulated Human Intestinal Epithelial Cells Through Inhibition of MAPKs and NF-kappa B

Moon DO, Choi SR, Lee CM, Kim GY, Lee HJ, Park YM

Intestinal epithelial cells (IECs) have been known to produce galactose-alpha1,4-galactose-beta1,4-glucose ceramide (Gb3) that play an important role in the mucosal immune response. The regulation of Gb3 is important to prevent...

Disruption of Microtubules Sensitizes the DNA Damage-induced Apoptosis Through Inhibiting Nuclear Factor kappaB (NF-kappaB) DNA-binding Activity

Lee H, Jeon J, Ryu YS, Jeong JE, Shin S, Zhang T, Kang SW, Hong JH, Hur GM

The massive reorganization of microtubule network involves in transcriptional regulation of several genes by controlling transcriptional factor, nuclear factor-kappa B (NF-kappaB) activity. The exact molecular mechanism by which microtubule rearrangement...

Impact of Lysophosphatidylcholine on the Plasminogen Activator System in Cultured Vascular Smooth Muscle Cells

Yoon BK, Kang YH, Oh WJ, Park K, Lee DY, Choi D, Kim DK, Lee Y, Rhyu MR

The balance between tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor type 1 (PAI-1) regulates fibrinolysis. PAI-1 expression increases in atherosclerotic arteries and vascular smooth muscle cells (VSMCs) are one...

Angiopoietin-1 variant, COMP-Ang1 attenuates hydrogen peroxide-induced acute lung injury

Kim SR, Lee KS, Park SJ, Min KH, Lee KY, Choe YH, Hong SH, Koh GY, Lee YC

Reactive oxygen species (ROS) play a crucial role in acute lung injury. Tissue inflammation, the increased vascular permeability, and plasma exudation are cardinal features of acute lung injury. Angiopoietin-1 (Ang1)...

Activation of NF-κB and AP-1 Mediates Hyperproliferation by Inducing β-Catenin and c-Myc in Helicobacter pylori-Infected Gastric Epithelial Cells

Byun E, Park B, Lim JW, Kim H

PURPOSE: In the gastric mucosa of Helicobacter pylori (H. pylori)-infected patients with gastritis or adenocarcinoma, proliferation of gastric epithelial cells is increased. Hyperproliferation is related to induction of oncogenes, such...

Retinoic acid inhibits inducible nitric oxide synthase expression in 3T3-L1 adipocytes

Yang JY, Koo BS, Kang MK, Rho HW, Sohn HS, Jhee EC, Park JW

  • KMID: 755207
  • Exp Mol Med.
  • 2002 Nov;34(5):353-360.
The present study was undertaken to explore whether retinoids, which are known to have immunomodulatory actions, could attenuate tumor necrosis factor-alpha (TNF)-stimulated inducible nitric oxide synthase (iNOS) expression in 3T3-L1...

Ox-LDL suppresses PMA-induced MMP-9 expression and activity through CD36-mediated activation of PPAR-gamma

Lee KJ, Kim HA, Kim PH, Lee HS, Ma KR, Park JH, Kim DJ, Hahn JH

  • KMID: 1103320
  • Exp Mol Med.
  • 2004 Dec;36(6):534-544.
During chronic inflammatory response, mono- cytes/macrophages produce 92-kDa matrix metalloproteinase-9 (MMP-9), which may contribute to their extravasation, migration and tissue remodeling. Activation of peroxisome proliferator- activated factor receptor-gamma (PPAR-gamma) has...

Kurarinone promotes TRAIL-induced apoptosis by inhibiting NF-kappaB-dependent cFLIP expression in HeLa cells

Seo OW, Kim JH, Lee KS, Lee KS, Kim JH, Won MH, Ha KS, Kwon YG, Kim YM

  • KMID: 1401757
  • Exp Mol Med.
  • 2012 Nov;44(11):653-664.
This study was designed to investigate the effects of the prenylated flavonoid kurarinone on TNF-related apoptosis inducing ligand (TRAIL)-induced apoptosis and its underlying mechanism. A low dose of kurarinone had...
