Abstract:

Objective To test dysbindin-1 expression during spermatogenesis and dysbindin-1 effect on histology of acrosome in mice. Methods Western blotting analysis was applied to detect the expression of dysbindin-1 in testis on day 7,14,21,28 and 35 postpartum and three-month old mice(n=3). The caudal spermatozoa was collected from sdy mice (no dysbindin-1expression), HE staining was performed for sperm morphology, fluorescein isothiocyanate conjugate-pisum sativum agglutinin (FITC-PSA) staining and immunofluorescence staining with antibody against sperm protein 56(sp56) for acrosome on sperm smear. Results Dysbindin-1A, not -1C, was expressed in postnatal testis development and spermatozoa. Mature sperm from sdy caudal epididymis had normal formation. Conclusion Dysbindin-1A, expressed in testis tissue and sperm during spermatogenesis, is not required for maintaining the morphology of sperm.
