TNF-alpha upregulates PTEN via NF-kappaB signaling pathways in human leukemic cells

Lee YR, Yu HN, Noh EM, Youn HJ, Song EK, Han MK, Park CS, Kim BS, Park YS, Park BK, Lee SH, Kim JS

  • KMID: 1103688
  • Exp Mol Med.
  • 2007 Feb;39(1):121-127.
TNF-alpha plays a variety of biological functions such as apoptosis, inflammation and immunity. PTEN also has various cellular function including cell growth, proliferation, migration and differentiation. Thus, possible relationships between...

Vitamin D3 up-regulated protein 1 controls the priming phase of liver regeneration

Kwon HJ, Hong SK, Yoon WK, Nam KH, Choi IP, Kim DY, Kim HC, Won YS

Vitamin D3 up-regulated protein 1 (VDUP1) is a potent growth suppressor that inhibits tumor cell proliferation and cell cycle progression when overexpressed. In a previous study, we showed that VDUP1...

Chemopreventive and metabolic effects of inulin on colon cancer development

Hijova E, Szabadosova V, Stofilova , Hrckova G

Prebiotics modulate microbial composition and ensure a healthy gastrointestinal tract environment that can prevent colon cancer development. These natural dietary compounds are therefore potential chemopreventive agents. Thirty Sprague-Dawley rats (4...

The efficacy of SPA0355 in protecting beta cells in isolated pancreatic islets and in a murine experimental model of type 1 diabetes

Bae UJ, Song MY, Jang HY, Gim HJ, Ryu JH, Lee SM, Jeon R, Park BH

  • KMID: 2154270
  • Exp Mol Med.
  • 2013 Nov;45(11):e51.
Cytokines activate several inflammatory signals that mediate beta-cell destruction. We recently determined that SPA0355 is a strong anti-inflammatory compound, thus reporting its efficacy in protecting beta cells from various insults....

Isoflavone-deprived soy peptide suppresses mammary tumorigenesis by inducing apoptosis

Park K, Choi K, Kim H, Kim K, Lee MH, Lee JH, Kim Rim JC

During carcinogenesis, NF-kappaB mediates processes associated with deregulation of the normal control of proliferation, angiogenesis, and metastasis. Thus, suppression of NF-kappaB has been linked with chemoprevention of cancer. Accumulating findings...
