【Abstract】 AIM To study whether there is a difference in the structure of V EGF gene between the normal tissue and the ovarian cancer overexpressing VEGF. METHODS VEGF cDNA was cloned from placenta by RT PCR. The ovarian cancer samples were collected in clinic.With the normal ovariantissue as the control, genomic DNA from the samples was extracted was extracted and compared with the normal ovarian tissue and Southern blotting was done. RESULTS VEGF cDNA clone from placenta was proved to be correct. There are three fragments (>30 kb,6.5 kb,2.5 kb) in normal control,while 10/19 samples only had two (>23kb and 4.3 kb).CONCLUSION The rearrangement of VEGF in the ovary cancer overexpressing VEGF does exist.更多还原
