Exploration of Novel Markers in Tan Sheep Spermatogenesis [PDF]
In livestock farming, the reproductive function and breeding performance of Tan sheep are crucial for enhancing farming efficiency. Despite advances in research on sheep germ cells, studies on the identification of markers for spermatogonia ...

Abundant A-to-I RNA editing in spermatocytes may suppress transposons to compensate for piRNA downregulation in male germlines [PDF]
The germline genome serves as a crucial battleground for transposon expansion, as transposons can increase their copy numbers in offspring when activated within germ cells.

Deletion of Hnrnpk Gene Causes Infertility in Male Mice by Disrupting Spermatogenesis
HnRNPK is a heterogeneous nuclear ribonucleoprotein (hnRNP) that has been firmly implicated in transcriptional and post-transcriptional regulation. However, the molecular mechanisms by which hnRNPK orchestrates transcriptional or post-transcriptional ...

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.

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 ...

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 ...

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.
