Background: Male factors, mainly spermatogenesis disorder, are responsible for 20-30% of infertility occurs in different societies. One of the known causes of spermatogenesis disorder is chemotherapy in patients with cancer. The side effect of chemoterpic agents may last from 10 years up to the end of the life. Since dividing cells are mainly affected by anticancer drugs, the aim of the present...

Mapping epigenetic modifications and identifying their roles in the regulation of spermatogenesis and embryogenesis are essential for gaining fundamental medical understandings and for clinical applications. More and more evidence has shown that specific epigenetic modifications are established during spermatogenesis, which will be transferred into oocyte via fertilisation, and play an importan...

BACKGROUND The Chinese mitten crab Eriocheir sinensis belongs to the Class Crustacea, Decapoda, Brachyura. The spermatozoon of this species is of aflagellated type, it has a spherical acrosome surrounded by the cup-shaped nucleus, which are unique to brachyurans. For the past several decades, studies on the spermatogenesis of the mitten crab mainly focus on the morphology. Compared with the ext...

As a chemotherapeutic drug, cyclophosphamide (CP) has negative impact on male fertility due to its reproductive toxicity. Melatonin (Mel) promotes the system and increases testosterone synthesis. This study is aimed at exploring molecular mechanism of Mel as protector against CP-induced cytotoxicity. A CP toxicity model was established in adult ICR mice by intraperitoneal injection 100 mg/kg ev...

One of the known causes of spermatogenesis disorder is chemotherapy in patients with cancer. The side effect of chemoterpic agents may last from 10 years up to the end of the life. Since dividing cells are mainly affected by anticancer drugs, the aim of the prese...

In a previous study we identified active Notch signaling in key cellular events occurring at adult spermatogenesis. In this study, we evaluated the function of Notch signaling in spermatogenesis through the effects of in vivo Notch blockade. Adult CD1 male mice were either submitted to a long term DAPT (?-secretase inhibitor) or vehicle treatment. Treatment duration was designed to attain one h...
