S-Adenosyl-L-methionine ameliorates TNFalpha-induced insulin resistance in 3T3-L1 adipocytes

Moon MK, Kim M, Chung SS, Lee HJ, Koh SH, Svovoda P, Jung MH, Cho YM, Park YJ, Choi SH, Jang HC, Park KS, Lee HK

An association between inflammatory processes and the pathogenesis of insulin resistance has been increasingly suggested. The IkappaB kinase-beta (IKK-beta)/ nuclear factor-kappaB (NF-kappaB) pathway is a molecular mediator of insulin resistance....

Interaction between the mouse homologue of CD99 and its ligand PILR as a mechanism of T cell receptor-independent thymocyte apoptosis

Park HJ, Ban YL, Byun D, Park SH, Jung KC

Here, we show that the interaction between two membrane proteins, the mouse homologue of CD99 (designated D4) and its ligand, paired immunoglobulin-like type 2 receptor (PILR), is one of the...

Overexpression and unique rearrangement of VH2 transcripts in immunoglobulin variable heavy chain genes in ankylosing spondylitis patients

Kim YJ, Kim N, Lee MK, Choi HJ, Baek HJ, Nam CH

To identify immunoglobulin variable heavy chain (VH) gene usages in Korean ankylosing spondylitis (AS) patients, expression level of VH2 genes from peripheral blood mononuclear cells (PBMCs) of 8 AS patients...

Chlorpromazine activates p21(Waf1/Cip1) gene transcription via early growth response-1 (Egr-1) in C6 glioma cells

Shin SY, Kim CG, Kim SH, Kim YS, Lim Y, Lee YH

2-Chloro-10-[3(-dimethylamino)propyl]phenothiazinemonohydrochloride (chlorpromazine) is a phenothiazine derivative used clinically to control psychotic disorders. It also exhibits an anticancer activity. Treatment with chlorpromazine (CPZ) results in cell-cycle arrest at the G2/M phase...

beta-Lapachone suppresses radiation-induced activation of nuclear factor-kappaB

Dong GZ, Oh ET, Lee H, Park MT, Song CW, Park HJ

Anticancer effects of beta-lapachone (beta-lap) are due to generation of ROS and metabolic catastrophes as a result of NAD(P)H:quinone oxidoreductase (NQO1)-mediated futile cycling between the oxidized and reduced forms of...

Involvement of MITF-A, an alternative isoform of mi transcription factor, on the expression of tryptase gene in human mast cells

Lee SH, Lee JH, Lee YM, Kim DK

Mast cells play a central role in the initiation and development of allergic diseases through release of various mediators. Tryptase has been known to be a key mediator in mast...

p190RhoGAP and Rap-dependent RhoGAP (ARAP3) inactivate RhoA in response to nerve growth factor leading to neurite outgrowth from PC12 cells

Jeon CY, Kim HJ, Lee JY, Kim J, Kim SC, Park JB

Rat pheochromocytoma (PC12) cells have been used to investigate neurite outgrowth. Nerve growth factor (NGF) has been well known to induce neurite outgrowth from PC12 cells. RhoA belongs to Ras-related...

Induction of the unfolded protein response and cell death pathway in Alzheimer's disease, but not in aged Tg2576 mice

Lee JH, Won SM, Suh J, Son SJ, Moon GJ, Park UJ, Gwag BJ

The endoplasmic reticulum (ER) stress results from disrupted protein folding triggered by protein mutation or oxidation, reduced proteasome activity, and altered Ca2+ homeostasis. ER stress is accompanied by activation of...

Genetic association of angiogenesis- and hypoxia-related gene polymorphisms with osteonecrosis of the femoral head

Hong JM, Kim TH, Kim HJ, Park EK, Yang EK, Kim SY

Multiple factors have been implicated in the development of osteonecrosis of the femoral head (ONFH). In particular, non-traumatic ONFH is directly or indirectly related to injury of the vascular supply...
