Toll-like receptor 9 dependent activation of MAPK and NF-kB is required for the CpG ODN-induced matrix metalloproteinase-9 expression

Lim EJ, Lee SH, Lee JG, Kim JR, Yun SS, Baek SH, Lee C

  • KMID: 1094665
  • Exp Mol Med.
  • 2007 Apr;39(2):239-245.
Unmethylated CpG oligodeoxynucleotides (CpG ODNs) activate immune cells to produce immune mediators. This study demonstrates that in murine macrophage RAW 264.7 cells, CpG ODN-mediated matrix metalloproteinase-9 (MMP-9) expression is regulated...

Cilostazol Protects Endothelial Cells Against Lipopolysaccharide-Induced Apoptosis Through ERK1/2- and P38 MAPK-Dependent Pathways

Lim JH, Woo JS, Shin YW

BACKGROUND/AIMS: We examined the effects of cilostazol on mitogen-activated protein kinase (MAPK) activity and its relationship with cilostazol-mediated protection against apoptosis in lipopolysaccharide (LPS)-treated endothelial cells. METHODS: Human umbilical vein...

Angiotensin III increases monocyte chemoattractant protein-1 expression in cultured human proximal tubular epithelial cells

Kim HW, Kim YO, Yoon SA, Han JS, Chun HB, Kim YS

BACKGROUND/AIMS: We investigated whether angiotensin III (Ang III) is involved in monocyte recruitment through regulation of the chemokine monocyte chemoattractant protein-1 (MCP-1) in cultured human proximal tubular epithelial cells (HK-2...

The effect of 5-aminoimidazole-4-carboxamide-ribonucleoside was mediated by p38 mitogen activated protein kinase signaling pathway in FRO thyroid cancer cells

Kim WG, Choi HJ, Kim TY, Shong YK, Kim WB

  • KMID: 2070111
  • Korean J Intern Med.
  • 2014 Jul;29(4):474-481.
BACKGROUND/AIMS: 5'-Adenosine monophosphate (AMP)-activated protein kinase (AMPK) is a cellular energy sensor that monitors intracellular AMP/adenosine triphosphate (ATP) ratios and is a key regulator of the proliferation and survival of...

CD137 induces adhesion and cytokine production in human monocytic THP-1 cells

Choi JW, Lee HW, Roh GS, Kim HH, Kwack KB

  • KMID: 755745
  • Exp Mol Med.
  • 2005 Apr;37(2):78-85.
CD137, which is expressed on activated T cells, plays a critical role in inflammatory responses. However, the exact role that CD137 plays in monocytes is not fully known. Here we...

C-Jun NH2-Terminal Kinase Contributes to Dexmedetomidine-Induced Contraction in Isolated Rat Aortic Smooth Muscle

Ok SH, Jeong YS, Kim JG, Lee SM, Sung HJ, Kim HJ, Chang KC, Kwon SC, Sohn JT

PURPOSE: Dexmedetomidine, a full agonist of alpha2B-adrenoceptors, is used for analgesia and sedation in the intensive care units. Dexmedetomidine produces an initial transient hypertension due to the activation of post-junctional...

Tetraspanin CD9 induces MMP-2 expression by activating p38 MAPK, JNK and c-Jun pathways in human melanoma cells

Hong IK, Kim YM, Jeoung DI, Kim KC, Lee H

  • KMID: 1056236
  • Exp Mol Med.
  • 2005 Jun;37(3):230-239.
Expression of matrix metalloproteinase-2 and -9 (MMP-2 and MMP-9), which correlates with tumor invasion and metastasis, has been known to be regulated by several intracellular signaling pathways. Since the CD9...

Curcumin inhibits the expression of COX-2 in UVB-irradiated human keratinocytes (HaCaT) by inhibiting activation of AP-1: p38 MAP kinase and JNK as potential upstream targets

Cho JW, Park K, Kweon GR, Jang BC, Baek WK, Suh MH, Kim CW, Lee KS, Suh SI

  • KMID: 1056230
  • Exp Mol Med.
  • 2005 Jun;37(3):186-192.
Ultraviolet B (UVB) irradiation of skin induces an acute inflammation. Cyclooxygenase-2 (COX-2) protein plays key roles in acute inflammation in UVB-irradiated keratinocyte cell line HaCaT. Recently, curcumin has been regarded...

Protective effects of fustin, a flavonoid from Rhus verniciflua tokes, on 6-hydroxydopamine-induced neuronal cell death

Park BC, Lee YS, Park HJ, Kwak MK, Yoo BK, Kim JY, Kim JA

  • KMID: 1047082
  • Exp Mol Med.
  • 2007 Jun;39(3):316-326.
6-Hydroxydopamine (6-OHDA) is a neurotoxin and is commonly used to generate experimental models of Parkinson's disease (PD). In this study, we investigated the signaling molecules involved in the 6-OHDA-induced cell...

Sterol-independent repression of low density lipoprotein receptor promoter by peroxisome proliferator activated receptor gamma coactivator-1alpha (PGC-1alpha)

Jeong JH, Cho S, Kim Pak Y

Peroxisome proliferator activated receptor (PPAR) gamma coactivator-1alpha (PGC-1alpha) may be implicated in cholesterol metabolism since PGC-1alpha co-activates estrogen receptor alpha (ERalpha) transactivity and estrogen/ERalpha induces the transcription of LDL receptor...
