Regulation of ATP-citrate lyase gene transcription

Kim KS, Kang JG, Moon YA, Park SW, Kim YS

It has been suggested that glucose metabolites and insulin are the most important factors inducing ATP-citrate lyase (ACL) by a high carbohydrate diet. We have used a primary culture of...

Regulation of fatty acid synthase at transcriptional and post-transcriptional levels in rat liver

Kim KS, Park SW, Kim YS

The regulation of fatty acid synthase in rat liver was investigated at transcriptional and post-transcriptional levels. When rats were fasted for 3 days and refed on a high-carbohydrate diet, the...

Regulation of expression of matrix metalloproteinase-9 by JNK in Raw 264.7 cells: presence of inhibitory factor(s) suppressing MMP-9 induction in serum and conditioned media

Lee YS, Lan Tran H, Van Ta Q

Matrix metalloproteinase-9 (MMP-9) secreted from macrophages plays an important role in tissue destruction and inflammation through degradation of matrix proteins and proteolytic activation of cytokines/chemokines. Whereas the MEK-ERK and PI3K-Akt...

Enhanced tyrosine hydroxylase expression in PC12 cells co-cultured with feline mesenchymal stem cells

Jin GZ, Yin XJ, Yu XF, Cho SJ, Lee HS, Lee HJ, Kong IK

Mesenchymal stem cells (MSCs) secrete a variety of neuroregulatory molecules, such as nerve growth factor, brain-derived neurotrophic factor, and glial cell-derived neurotrophic factor, which upregulate tyrosine hydroxylase (TH) gene expression...

The Ketogenic Diet Suppresses the Cathepsin E Expression Induced by Kainic Acid in the Rat Brain

Jeong HJ, Kim H, Kim YK, Park SK, Kang DW, Yoon D

PURPOSE: The ketogenic diet has long been used to treat epilepsy, but its mechanism is not yet clearly understood. To explore the potential mechanism, we analyzed the changes in gene...

Expression and Regulation of Endothelial Nitric Oxide Synthase by Vascular Endothelial Growth Factor in ECV 304 Cells

Park JS, Hong GR, Baek SW, Shin DG, Kim YJ, Shim BS

Nitric oxide (NO) seems to play a pivotal role in the vascular endothelial growth factor (VEGF)-induced endothelial cell proliferation. This study was designed to investigate the role and intracellular signal...

Expression of hOGG1 protein during differentiation of HL-60 cells

Lee YS, Lee KH, Chung MH

  • KMID: 1097257
  • Exp Mol Med.
  • 2003 Apr;35(2):98-105.
Human 8-oxo-G-DNA glycosylase 1 (hOGG1) is a DNA glycosylase to cleave 8-oxo-7,8-dihydroguanine (8-oxo-G), a mutagenic DNA adduct formed by oxidant stresses. Here, we examined hOGG1 protein expression and repair activity...

Impacts of Cytosolic Phospholipase A2, 15-Prostaglandin Dehydrogenase, and Cyclooxygenase-2 Expressions on Tumor Progression in Colorectal Cancer

Lim SC, Cho H, Lee TB, Choi CH, Min YD, Kim SS, Kim KJ

PURPOSE: In addition to cyclooxygenase-2 (COX-2) which is related to prostaglandin E2 synthesis, other enzymes such as cytosolic phospholipase A2 (cPLA2), microsomal prostaglandin E2 synthase-1 (mPGES-1), and 15-prostaglandin dehydrogenase (15-PGDH)...

Aldosterone-induced TGF-beta1 Expression is Regulated by Mitogen-Activated Protein Kinases and Activator Protein-1 in Mesangial Cells

Han JS, Cho BS, Yang CW, Kim YS

Aldosterone has been shown to stimulate renal TGF-beta1 expression. However, the mechanisms for aldosterone-induced TGF-beta1 expression have not been clearly determined in mesangial cells. We examined the role of extracellular-signal...

15-Deoxy-delta 12,14-ProstaglandinJ2 Regulates Dedifferentiation through Peroxisome Proliferator-Activated Receptor-gamma-Dependent Pathway but Not COX-2 Expression in Articular Chondrocytes

Lee JH, Yu SM, Yoon EK, Lee WK, Jung JC, Kim SJ

Peroxisome proliferator-activated receptors-gamma (PPAR-gamma) is critical for phenotype determination at early differentiation stages of mesenchymal cells, whereas its physiological role is unclear. Therefore, we investigated the role of 15-deoxy-delta 12,14-prostaglandinJ2...
