Problem:
To reveal the effect of p53-tristetraprolin-stathmin-1 signaling on trophoblasts and recurrent spontaneous abortion (RSA).
Method Of Study:
Stathmin-1 (STMN1), p53, and tristetraprolin (TTP) expression in paraffin-embedded villus tissue was determined using immunohistochemistry. HTR-8/SVneo cells were treated with doxorubicin to activate p53; STMN1 and TTP levels were detected by quantitative reverse transcription-PCR and western blotting. Western blotting and immunofluorescence were used to investigate STMN1 expression after TTP overexpression or knockdown in HTR-8 cells.
Results:
STMN1 was downregulated and p53 was upregulated in the villus tissue from patients with RSA. Doxorubicin decreased STMN1 expression but enhanced TTP expression in HTR-8 cells. In vitro, TTP overexpression inhibited STMN1 production; TTP knockdown promoted it. TTP downregulated STMN1 expression in trophoblasts by directly binding its 3' untranslated region.
Conclusions:
TTP modulates trophoblast function and interacts with STMN1 and p53, and is related to pregnancy outcomes.
