[Association of the novel hydatidiform mole-related gene F10 with the invasiveness of trophoblastic tumor].

Objective: To study the expressions of the novel gene F10 associated with hydatidiform mole in different trophoblastic tumors and explore the relation of F10 expression with the invasiveness of malignant trophoblastic tumor.

Methods: In situ hybridization was used to study the expression of F10 in 12 cases of hydatidiform mole, 6 cases of invasive mole, and 8 cases of choriocarcinoma.

Results: F10 mRNA was positive in all cases of hydatidiform mole, invasive mole, and choriocarcinoma, and the expression intensity significantly increased in the order of hydatidiform mole, invasive mole and choriocarcinoma (P<0.001).

Conclusion: The expression of F10 gene may relate to the occurrence and invasiveness of trophoblastic tumor, with possible involvement in the invasion or malignant changes of trophoblastic cells.
