Introduction:
The expression of bone morphogenetic protein-10 (BMP-10) is downregulated in some cancer types, but its function and mechanism in ovarian cancer remains unclear.
Materials And Methods:
BMP-10 expression was detected in ovarian cancer tissues and cell lines by using immunochemistry and western blotting. Prognostic value of BMP-10 was evaluated by Kaplan-Meier curve and Cox regression model. Knockdown or overexpression of BMP-10 was conducted by using specific siRNA or pcDNA-BMP-10 in ovarian cancer cell lines. The biological features induced by BMP-10 were observed by MTT assay, wound-healing and transwell assays.
Results:
BMP-10 expression in ovarian cancer tissues was significantly lower than that in ovarian tissues. Low BMP-10 expression in ovarian cancer tissues was related to advance FIGO stage, higher histologic grade, lymph node metastasis, and peritoneal fluid. Kaplan-Meier analysis revealed that low BMP-10 expression was significantly associated with poor prognosis of patients with ovarian cancer. BMP-10 overexpression or knockdown significantly inhibited or promoted proliferation, migration, and invasion of ovarian cancer cells, respectively. Moreover, administration of neutralizing antibody or human recombinant BMP-10 would reverse these effects on ovarian cancer cells.
Conclusion:
Low BMP-10 expression was associated with poor prognosis and progression of ovarian cancer.
