title: [Effect of Saikosaponin-d on up-regulating GR mRNA expression and inhibiting cell growth in human leukemia cells].
abstract: OBJECTIVE
  To study the effect of Saikosaponin-d (SSd) on the expression of glucocorticoid receptor (GR) mRNA and cell growth in HL60 cells.
  
  
  METHODS
  Antiproliferation effects of SSd on HL60 cells were determined by 3H-thymidine incorporation. Cell cycle analysis was also performed by flow cytometry. GRmRNA was analyzed by northern blot analysis.
  
  
  RESULTS
  After 48 hours treatment with 10 micrograms/ml SSd, 3H-thymidine incorporation decreased in HL60 cells and the effect was time and dose dependent. The flow cytometry analysis showed HL60 cells were arrested at G0/G1 phase. The expression of GR mRNA increased.
  
  
  CONCLUSIONS
  SSd exhibits the inhibition effects on cell growth in HL60 cells and could up-regulate the expression of GR mRNA in HL60 cells.
