Abstract:
Purpose:To investigate p53 gene mutation, CD44V6 expression and their relationship with metastasis of ovarian carcinoma in tumor diagnosis. Methods:PCR SSCP with silver staining was used to detect the mutation of p53 gene; by using Southern blot and image analysis, the quantitative and qualitative expression of CD44V6 were also determined. Results:The positive percentage of CD44V6 expression and p53 gene mutation was not detectable in any of the normal ovarian specimens but in the benign tumors, non metastasizing and metastasizing carcinomas it was 10%, 75%, 88% and 5%, 40%, 60% respectively. The mean dark density of each band in these four groups(mentioned above) was 85.25?23.16, 817.11?126.5, 3820.14?289.43 and 10132.92?1521.20 respectively. The expression of CD44V6 of metastasizing carcinomas was higher than that of non metastasizing group. Conclusions:The expression of CD44V6 is related to tumor metastasis; the positive percentage of CD44V6 is higher than that of p53 gene mutation in the group of metastasizing and non metastasizing tumors; Compared to p53 gene mutation, CD44V6 is a better marker for tumor metastasis.
