title: [WT inhibit human hepatocellular carcinoma BEL-7402 cells growth by modulating Akt and ERK1/2 phosphorylation].
abstract: OBJECTIVE
  To investigate effects of Akt and ERK1/2 signaling pathways on waltonitone (WT) induced cell growth inhibition in human hepatocellular carcinoma BEL-7402 cells.
  
  
  METHODS
  Cell viability of BEL-7402 cells was examined using MTT assay. Phosphorylation of E Akt and RK1/2 were detected by Western blot analysis, while cell cycle distribution of BEL7402 cells was analyzed by flow cytometry.
  
  
  RESULTS
  WT could inhibit the BEL-7402 cells growth, induce the S-phase cell cycle arrest, activate Akt and ERK1/2 phosporylation. Moreover, the cell growth inhibition and S-phase cell cycle arrest induction of WT on BEL-7402 cells could be blocked by Akt and ERK1/2 inhibitors.
  
  
  CONCLUSIONS
  WT induce the cell cycle arrest and inhibit the cell growth on BEL-7402 cells by modulating Akt and ERK1/2 phosphorylation.
