Endothelin 1 protects HN33 cells from serum deprivation-induced neuronal apoptosis through Ca2+-PKCalpha-ERK pathway

Park MH, Lee DH

Endothelins (ETs), which were originally found to be potent vasoactive transmitters, were known to be implicated in nervous system, but the mode of mechanism remains unclear. ETs (ET-1, ET-2, and...

Implication of phosphorylation of the myosin II regulatory light chain in insulin-stimulated GLUT4 translocation in 3T3-F442A adipocytes

Choi YO, Ryu HJ, Kim HR, Song YS, Kim C, Lee W, Choe H, Leem CH, Jang YJ

  • KMID: 1111411
  • Exp Mol Med.
  • 2006 Apr;38(2):180-189.
In adipocytes, insulin stimulates glucose transport primarily by promoting the translocation of GLUT4 to the plasma membrane. Requirements for Ca2+/ calmodulin during insulin-stimulated GLUT4 translocation have been demonstrated; however, the...

Cytosolic accumulation of gammaH2AX is associated with tropomyosin-related kinase A-induced cell death in U2OS cells

Jung EJ, Kim CW, Kim DR

Tropomyosin-related kinase A (TrkA) plays an important role in cell survival, differentiation, and apoptosis in various neuronal and nonneuronal cell types. Here we show that TrkA overexpression by the Tet-On...

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...

Lee HJ, Cho ED, Lee KW, Kim JH, Cho SG, Lee SJ

  • KMID: 2154241
  • Exp Mol Med.
  • 2013 May;45(5):e22.
The accumulation of abnormal protein aggregates is a major characteristic of many neurodegenerative disorders, including Parkinson's disease (PD). The intracytoplasmic deposition of alpha-synuclein aggregates and Lewy bodies, often found in...
