Abstract:
Objective To investigate whether antisense integrin αV and β3 gene therapy has antitumor activity for hepatocellular carcinoma.Methods In this study,120 male nude mice at the age of 4 weeks old were devided into 4 groups randomly.The antisense integrin αV and β3 expression vectors were iniected into HepG2 hepatomas established in nude mice to monitor tumor growth after 6 weeks.Tumot inhibit rate was calculated.Tunor microvessel density(MVD)was determined by immunohistochemical staining,and tumor apoptosis by TUNEL. Results The tumor weight of the control group,αV group,β3 group and αVβ3 group was(1.38±0.92)g、(1.28±0.27)g、(1.30±0.34)g、(1.08±0.16)g respectively.The difference between each two groups was significant(q12=4.76,q13=3.73,q14=14.28,P<0.05);The MVD was(17.53±1.88)、(16.06±1.92)、(15.83±2.00)、(14.86±1.69)respectively,(q12=3.91,q13=4.55,q14=7.13,P<0.01);The AI of the control group,αV group,β3 group and αVβ3 group was 10.53%±3.29%,19.80%±4.06%,21.93%±3.26%,24.03%±4.45%respectively,with the difference being significant among groups(q12=29.41,q13=33.52,q14=39.7,P<0.01).Conclusions Antisense gene therapy targeting αV and β3 integrins exerts dramatic inhibition on the growth of the tumor.
