Exploration of Novel Markers in Tan Sheep Spermatogenesis [PDF]

open access: yesAnimals
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]

open access: yesRNA Biology
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

open access: yesCells, 2022
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 ...

Evaluation of the Protective Effect of Vitamin C on Spermatocytes in Rats with Pentylenetetrazole-Induced Epilepsy Using Immunohistochemistry

open access: yesمجله دانشکده پزشکی اصفهان, 2020
Background: There has not been yet reports regarding the protective effect of vitamin C on spermatocytes in epileptic rats. The present study aimed to evaluate the protective role of vitamin C on numbers and structure spermatocytes in rats with ...

Zbtb40 Deficiency Leads to Morphological and Phenotypic Abnormalities of Spermatocytes and Spermatozoa and Causes Male Infertility

open access: yesCells, 2023
Studies on the gene regulation of spermatogenesis are of unusual significance for maintaining male reproduction and treating male infertility. Here, we have demonstrated, for the first time, that a loss of ZBTB40 function leads to abnormalities in the ...

SYMPK Is Required for Meiosis and Involved in Alternative Splicing in Male Germ Cells

open access: yesFrontiers in Cell and Developmental Biology, 2021
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

open access: yesFrontiers in Endocrinology, 2021
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]

open access: yesJournal of Bioscience and Applied Research, 2015
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 ...

Immunohistochemical localization of glucose transporter 1 and 3 in the scrotal and abdominal testes of a dog

open access: yesLaboratory Animal Research, 2017
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 ...
