Interferon induced transmembrane protein-1 (Ifitm-1) has been reported to have an important role in primordial germ cell formation, and it has expressed in female reproductive organ. In the present study, Ifitm-1 gene expression was identified in testes and all part of epididymis using western immunoblot and immunohistochemistry. Interestingly,Ifitm-1 expression was observed on the head of spermatozoa. To investigate the role of Ifitm-1 gene expression in behavior of spermatozoa after acrosome reaction, fresh sperm was incubated with calcium ionophore to induce acrosome reaction, whereas the expression of Ifitm-1 was not altered after the acrosome reaction. Then to identify the effect of Ifitm-1 in sperm motility and other seminal parameters, different concentration of Ifitm-1 antibody was incubated with spermatozoa, and seminal parameters were assessed using computer-assisted semen analysis (CASA).
Interestingly, motility, progressive, and VAP were increased in the sperm with Ifitm-1 antibody treated compared to rabbit serum, however other parameters such as straightness were not changed. In order to identify the functional significance of Ifitm-1 in fertilization, capacitated spermatozoa were pre-incubated with anti- Ifitm-1 antibody and subsequently examined the ability to adhere to mouse oocytes. However, any defection or alteration in sperm-egg fusion was not found, Ifitm-1 antibody treated or non-treated spermatozoa showed a normal penetration. Although the precise role of Ifitm-1 in sperm motility and following fertilization need to be elucidated, this study suggests that the activation of Ifitm-1 on the sperm may enhance the motility of spermatozoa in mice.*표시는 필수 입력사항입니다.
