title: [Experimental study of Ginkgo biloba exocarp polysaccharides on HL-60 cells in vitro].
abstract: OBJECTIVE
  To study the effect of Ginkgo biloba exocarp polysaccharides (GBEP) on HL-60 cells in vitro.
  
  
  METHODS
  Cell culture, MTT, flow cytometry were performed to observe proliferation, apoptosis and changes of relevant gene expression of HL-60 cells.
  
  
  RESULTS
  GBEP (40-160 mg/L, 48 h) could inhibit HL-60 cells proliferation and the expression of proliferation-promotion gene c-myc, induce HL-60 cells apoptosis and down-regulate the expression of apoptosis-inhibitory gene bcl-2.
  
  
  CONCLUSIONS
  Influence of GBEP on HL-60 cells proliferation and apoptosis may relate to its effects on the expression of proliferation-promotion gene c-myc and apoptosis-inhibitory gene bcl-2.
