Involvement of JNK-initiated p53 accumulation and phosphorylation of p53 in pseudolaric acid B induced cell death

Gong X, Wang M, Tashiro SI, Onodera S, Ikejima T

  • KMID: 1110127
  • Exp Mol Med.
  • 2006 Aug;38(4):428-434.
A terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay was used to determine that apoptosis causes HeLa cell death induced by pseudolaric acid B. The c-Jun N-terminal kinase (JNK) inhibitor...

Differential effects of Fas cross-linking on phospholipase D activation and related lipid metabolism in Fas-resistant A20 cells.

Lim SY, Lee SC, Shin IC, Han JS

  • KMID: 1380228
  • Exp Mol Med.
  • 2002 Jul;34(3):201-210.
A20 murine lymphoma cells undergoing Fas-mediated apoptosis showed increase in the activity of phospholipase D (PLD), which is involved in proliferative or mitogenic cellular responses. Using A20 cell lines that...

Infarct Size-limiting Effect of Calcium Preconditioning in Rabbit Hearts

Kim HD

Recent studies demonstrated that brief period of Ca2+ depletion and repletion (Ca2+ preconditioning, CPC) has strong protective effects against ischemia in a rat heart. CPC and classic preconditioning (IPC) were...
