ABSTRACT
OBJECTIVE:
To study the expression of vascular endothelial growth factor (VEGF) mRNA isoforms in ovarian carcinoma and to explore their role in tumorigenesis and development of ovarian carcinoma.METHODS:
The types and levels of VEGF mRNA isoforms of surgical samples from 30 patients with ovarian carcinoma were determined by relatively quantative RT-PCR, nest PCR and sequence analysis.RESULTS:
VEGF(121), VEGF(145), VEGF(165) and VEGF(189)mRNA were detected in normal ovaries and ovarian carcinoma tissues. The expression level of VEGF(121) was significantly higher than that of VEGF(145), VEGF(165) and VEGF(189) (P<0.001, respectively). The expression of all 4 isoforms in carcinoma tissues was increased significantly compared with that in normal ovaries (P<0.05).CONCLUSION:
Overexpression of VEGF(121), VEGF(145), VEGF (165) and VEGF(189) mRNA, especially VEGF(121), was found in varian carcinoma tissues. This findings suggest that all 4 VEGF isoforms may be involved in the tumorigenesis and development of ovarian carcinoma and VEGF(121) may play a key role.
