Boule基因在小鼠精子發(fā)生過程中的動態(tài)表達
[Abstract]:Aim: to investigate the dynamic expression of male sterility related gene (Boule) in the first spermatogenesis wave in mice and to explore the regulatory role of Boule in spermatogenesis. Methods: the expression of BOULE protein in multiple tissues was analyzed by Western blot. The expression of Boule m RNA and BOULE proteins in the first spermatogenesis wave of male mice was detected by real-time fluorescence quantitative, immunohistochemical and immunofluorescence techniques. Results the specific expression of BOULE protein was high in testis by Western blotting, and could be detected in testis 16 days after birth. The results of real-time fluorescence quantitative analysis of the continuous expression of Ts2 in the developing testis and adult testis confirmed that Boule m RNA could be detected in the testis of male mice at 14 days postnatal, and the expression peak was detected in the testis of male mice at day 20. Immunohistochemical staining showed that the expression peak was observed in the fine spermatozoa of spermatozoa. Positive signals of BOULE protein were found in cytoplasm of spermatozoa and round spermatozoa. Conclusion the specific expression of Boule during spermatogenesis is precisely regulated at the developmental level. The specific expression of Boule in spermatocytes and round spermatozoa suggests that Boule may play a role in spermatocyte progression and round spermatocyte.
