| Outline of Final Research Achievements |
We demonstrated that the exosome from ovarian cancer stimulated the peritoneal dissemination. By mouse model the exosome also prompted abdominal metastasis and causes morphological change in mesothelial cells. This phenomenon was caused by induction of apoptosis. We observed that the exosome increased MMP1 expression in mesothelial cells.
Using clinical data base, we observed that MMP1 is an important prognostic marker and there are ovarian cancer patients with ascites including MMP1 mRNA.
In conclusion, the exosome including MMP1 mRNA may be a prognostic biomarker and a treatment target for preventing abdominal metastasis.
