ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of antisense oligonucleotide specific to K-ras point mutation on human pancreatic carcinoma cell PC-2 in vitro.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>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.</p>
