Objective:To study the effects on human glioma cell line CHG-5 by ultrasonic microbubble intensifier with survivin antisense oligonucleotides (ASODN)transfection. Methods: Antisense oligonucleotides targeting survivin mRNA was designed and synthesized.Four regimen groups were designed,group A:survivin antisense oligonucleotides transfected with ultrasonic microbubble intensifier combined with ultrasound irradiation,group B: survivin antisense oligonucleotides transfected with lipofectamine combined with ultrasound irradiation,group C:survivin antisense oligonucelotides with lipofectamine transfection.group D:blank control.The expression changes of surviving protein were measured by immunohistochemical staining and Western blotting,and MTr assay was used to measure the changes of proliferation.Results:Survivin protein expression in group A was decreased significantly in human glioma cell line CHG-5 than other groups(P<0.05),and the proliferating rate of CHG-5 in group A was also significantly inhibited(P<0.05).Conclusion:Ultrasonic microbubble intensifier transfection combined with ultrasound irradiation is a promising method in gene transfection effectively and noninvasively.
