Exploring the role of mononuclear phagocytes in the epididymis

open access: yesAsian Journal of Andrology, 2015
The onslaught of foreign antigens carried by spermatozoa into the epididymis, an organ that has not demonstrated immune privilege, a decade or more after the establishment of central immune tolerance presents a unique biological challenge.

Two bromodomain proteins functionally interact to recapitulate an essential BRDT-like function in Drosophila spermatocytes [PDF]

open access: yesOpen Biology, 2015
In mammals, the testis-specific bromodomain and extra terminal (BET) protein BRDT is essential for spermatogenesis. In Drosophila, it was recently reported that the tBRD-1 protein is similarly required for male fertility.

Negative biomarker based male fertility evaluation: Sperm phenotypes associated with molecular-level anomalies

open access: yesAsian Journal of Andrology, 2015
Biomarker-based sperm analysis elevates the treatment of human infertility and ameliorates reproductive performance in livestock. The negative biomarker-based approach focuses on proteins and ligands unique to defective spermatozoa, regardless of their ...

Differing requirements for Augmin in male meiotic and mitotic spindle formation in Drosophila [PDF]

open access: yesOpen Biology, 2014
Animal cells divide using a microtubule-based, bipolar spindle. Both somatic, mitotic cells and sperm-producing male meiotic spermatocytes use centrosome-dependent and acentrosomal spindle-forming mechanisms.

Spermatocytic Seminoma in the Rat [PDF]

open access: yesToxicologic Pathology, 1985
During the necropsy of a 2-yr-old untreated control rat from a carcinogenicity study, a tan brown nodular mass was observed within the tunica albuginea of one testis. Both testes were processed for light and transmission electron microscopy. Histologically, the testicular mass was composed of round to polyhedral cells with distinct cell boundaries ...

Unique properties of Drosophila spermatocyte primary cilia

open access: yesBiology Open, 2013
Summary The primary cilium is an essential organelle required for animal development and adult homeostasis that is found on most animal cells. The primary cilium contains a microtubule-based axoneme cytoskeleton that typically grows from the mother ...

Ezrin: a regulator of actin microfilaments in cell junctions of the rat testis

open access: yesAsian Journal of Andrology, 2015
Ezrin, radixin, moesin and merlin (ERM) proteins are highly homologous actin-binding proteins that share extensive sequence similarity with each other.

Putting things in place for fertilization: discovering roles for importin proteins in cell fate and spermatogenesis

open access: yesAsian Journal of Andrology, 2015
Importin proteins were originally characterized for their central role in protein transport through the nuclear pores, the only intracellular entry to the nucleus.

Are sperm capacitation and apoptosis the opposite ends of a continuum driven by oxidative stress?

open access: yesAsian Journal of Andrology, 2015
This chapter explores the possibility that capacitation and apoptosis are linked processes joined by their common dependence on the continued generation of reactive oxygen species (ROS).

Sperm DNA fragmentation, recurrent implantation failure and recurrent miscarriage

open access: yesAsian Journal of Andrology, 2015
Evidence is increasing that the integrity of sperm DNA may also be related to implantation failure and recurrent miscarriage (RM). To investigate this, the sperm DNA fragmentation in partners of 35 women with recurrent implantation failure (RIF ...
