ABSTRACT
Objective:
To investigate whether phosphorothioate-modified antisense vascular endothelial growth factor oligodeoxynucleotides ( VEGF-ASODN) formulated in cationic liposome can inhibit the blood flow of lung cancer.Methods:
Lewis lung tumor models were established by subcutaneous injection of Lewis lung carcinoma cells into the right flank of 40 C57BL/6 mice. Twenty-four hours later, mice were randomly assigned into 4 groups; pure liposome, liposome containing ASODN, SODN and MODN. Mice in each group were treated twice a week for 4 weeks. Tumor growth were determined. Peak systolic flow velocity (PS) and resistance index (RI) were measured with a sonographic scanner. Expression of VEGF mRNA were detected by hybridization in situ and RT-PCR.Results:
ASODN significantly suppressed the growth of subcutaneous tumors. PS and RI in VEGF-ASODN group were significantly different from those in other 3 groups ( P
