Sirt1 is a member of the sirtuin family of proteins and has important roles in numerous biological processes. Sirt1-/- mice display an increased frequency of abnormal spermatozoa, but the mechanism of Sirt1 in spermiogenesis remains largely unknown. Here, we report that Sirt1 might be directly involved in spermiogenesis in germ cells but not in steroidogenic cells. Germ cell-specific Sirt1 knoc...
SPERMATOGENESIS IS A COMPLEX PROCESS OF TERMINAL DIFFERENTIATION BY WHICH MATURE SPERMS ARE GENERATED, AND IT CAN BE DIVIDED INTO THREE PHASES: mitosis, meiosis and spermiogenesis. In a previous study, we established a series of proteomic profiles for spermatogenesis to understand the regulation of male fertility and infertility. Here, we further investigated the localization and the role of fl...
Globozoospermia syndrome is a rare teratozoospermia with an incidence below 0.1%. Presence of 100% round sperm heads, absence of acrosome, and messy sperm body and tail are the main characteristics of this syndrome. The activation ability of oocytes and consequently the fertilization rate decrease due to the absence of acrosome. The pathogenesis of this syndrome is not clear [1-2]. Globozoosper...
