title: Liposome-C-erbB2 antisense oligodoxynucleotides in human ovarian cancer cells.
abstract: OBJECTIVE
  To explore the effects of liposome-C-erbB2 antisense phosphorothioate oligodeoxynucleotides (S-ODNs) on C-erbB2 proto-oncogene expression and cell proliferation in human ovarian cancer cells.
  
  
  METHODS
  The effects of liposome-C-erbB2 S-ODNs on C-erbB2 protein expression, cell cycle and cell proliferation in human ovarian cancer cells were studied by means of flow cytometry and 3H-thymidine incorporation.
  
  
  RESULTS
  Liposome-C-erbB2 S-ODNs can specifically reduce C-erbB2 protein expression in human ovarian cancer cells, accompanied by a 30% inhibition of cell proliferation. The effectiveness of liposome-C-erbB2 S-ODNs on the expression of C-erbB2 was about 40 times higher than that of C-erbB2 S-ODNs.
  
  
  CONCLUSIONS
  The data suggest that antisense therapy might be a useful method of gene therapy in ovarian cancer. The effectiveness of C-erbB2 S-ODNs could be greatly increased by adsorption of S-ODNs by liposomes.
