title: [The study of the effect of antisense oligonucleotide specific to K-ras point mutation on human pancreatic carcinoma cell PC-2].
abstract: OBJECTIVE
  To investigate the effects of antisense oligonucleotide specific to K-ras point mutation on human pancreatic carcinoma cell PC-2 in vitro.
  
  
  METHODS
  Human pancreatic carcinoma cell PC-2 was transducted with antisense oligonucleotide specific to K-ras point mutation by liposome; the expression of target gene was studied with immunohistochemistry and in situ hybridization. The effect on cell proliferation was studied by artificial count, MTT and mass test.
  
  
  RESULTS
  The expression degree of ras protein and K-ras mRNA transducted with antisense oligonucleotide decreased apparently compared with control group and sense oligonucleotide group 48 h after tansduction. The inhibitory effect on cell proliferation was confirmed by artificial count, MTT and mass test.
  
  
  CONCLUSIONS
  Antisense oligonucleotide specific to K-ras point mutation has an apparent inhibitory effect on target gene expression and cell proliferation of human pancreatic carcinoma cell in vitro.
