[Increased expressions of Blimp-1 and Bcl-6 in the deciduas of patients with unexplained recurrent spontaneous abortion].

Objective To oberseve the expressions of B cell lymphoma 6 (Bcl-6) and B lymphocyte-induced maturation protein 1 (Blimp-1) in the decidua of patients with unexplained recurrent spontaneous abortion (URSA), and investigate the roles that Bcl-6 and Blimp-1 act in URSA. Methods Decidual tissues were collected from patients with URSA (URSA group) and normal pregnant women (control group). Then, we detected the expressions of Bcl-6 and Blimp-1 in the deciduas of the two groups using real-time fluorescent quantitative PCR and immunohistochemistry. The relationship between Blimp-1 and Bcl-6 was estimated by Pearson's correlation analysis. Results Compared with the control group, the levels of Blimp-1 mRNA and protein, Bcl-6 mRNA significantly increased in the URSA group. However, Bcl-6 protein was raised insignificantly in URSA group. Furthermore, there was a positive correlation between Bcl-6 and Blimp-1 at the level of mRNA. Conclusion The expressions of Bcl-6 and Blimp-1 are enhanced in the deciduas of URSA patients.
