Small interfering RNA molecules targeting endothelin-converting enzyme-1 inhibit endothelin-1 synthesis and the invasive phenotype of ovarian carcinoma cells.

Endothelin-1 (ET-1) has been implicated in the progression of various cancers, including ovarian carcinoma. We found that the ovarian carcinoma cell lines ES2 and OVCAR3 and tumors from different anatomic sites expressed ET-1 system members [ET receptor A and ET-converting enzyme-1 (ECE-1)]. However, only ECE-1 was significantly higher in the solid tumors… CONTINUE READING
