| Research Abstract |
The origin of ovarian clear cell carcinoma and ovarian endometrioid caricinoma has been speculated to derive from endometriosis. In this research, we revealed the mechanism of carcinogenesis of ovarian clear cell carcinoma and ovarian endometrioid carcinoma from endometriosis. We analyzed both p53 gene mutation using DNA extracted from pathological section of ovarian clear cell carcinoma and ovarian endometrioid carcinoma with endometriosis obtained by Laser Microdissection method, and the allele frequency of the amino acid variation (c.215 G>C Arg72Pro) of the p53 gene codon72 using ovarian cancer patient's genomic DNA. We found that p53 gene mutation was detected in ovarian clear cell carcinoma with endometriosis cells and not in ovarian endometrioid carcinoma of endometriosis, and Pro/Pro allele frequency increased in ovarian cancer patients(P<0.003). These results suggested that the factor p53 gene mutation is related in the specialization of different pathological types and that p53 codon72 Pro/Pro allele is a risk factor of ovarian cancer.
