Ultrastructural evidence of spermatogenesis in the rusty parrotfish, Scarus ferrugineus (Teleostei Scaridae). [PDF]
This work analyses the spermatogenesis in the males of Scarus ferrugineus from histological and ultrastructural points of view. This study was carried out during the period of formation of spermatozoa thus being able to determine the pattern of ...

Meiotic Chromosome Synapsis and XY-Body Formation In Vitro
To achieve spermatogenesis in vitro, one of the most challenging processes to mimic is meiosis. Meiotic problems, like incomplete synapsis of the homologous chromosomes, or impaired homologous recombination, can cause failure of crossover formation and ...

Analysis of DNA methylation changes following Cfp1 knockout in mouse spermatocytes [PDF]
Objective Spermatogenesis is a complex biological process that encompasses meiosis in spermatocytes and the dynamic epigenetic alterations that ensure the inheritance of genetic traits.

Glucose is essential for testicular function; the uptake of carbohydrate-derived glucose by cells is mediated by glucose transporters (GLUTs). In the present study, we investigated the activity of GLUT1 and GLUT3, the two main isoforms of GLUTs found in ...

SYMPK Is Required for Meiosis and Involved in Alternative Splicing in Male Germ Cells
SYMPK is a scaffold protein that supports polyadenylation machinery assembly on nascent transcripts and is also involved in alternative splicing in some mammalian somatic cells. However, the role of SYMPK in germ cells remains unknown.

UBR2 of the N-end rule pathway is required for chromosome stability via histone ubiquitylation in spermatocytes and somatic cells [PDF]
The N-end rule pathway is a proteolytic system in which its recognition components (N-recognins) recognize destabilizing N-terminal residues of short-lived proteins as an essential element of specific degrons, called N-degrons.

Abstract Spermatocytic seminoma is a rare germ cell tumor distinct from classical seminoma, both clinically and pathologically. It affects older men, has not been associated with a history of cryptorchidism, and has no known counterpart in ovary or any other site.

A surge of late-occurring meiotic double-strand breaks rescues synapsis abnormalities in spermatocytes of mice with hypomorphic expression of SPO11 [PDF]
Meiosis is the biological process that, after a cycle of DNA replication, halves the cellular chromosome complement, leading to the formation of haploid gametes.

An orchestrated intron retention program in meiosis controls timely usage of transcripts during germ cell differentiation [PDF]
Global transcriptome reprogramming during sper-matogenesis ensures timely expression of factors in each phase of male germ cell differentiation. Sper-matocytes and spermatids require particularly exten-sive reprogramming of gene expression to switch from
