Transcriptome analyses in infertile men reveal germ cell–specific expression and splicing patterns

Life Science Alliance, 2023
We uncover extensive germ cell type–dependent transcriptome changes in human spermatogenesis and demonstrate the potential of alternative splicing in the regulation of spermatogenesis.

Antipsychotics and spermatogenesis, which is the impact?: A review of literature

European Psychiatry, 2023
Introduction Antipsychotics are among the most widely prescribed molecules in psychiatry. Their sexual side effects are frequent, generally underestimated by clinicians and subjectively poorly tolerated by patients.

Chromatin-Associated Protein Sugp2 Involved in mRNA Alternative Splicing During Mouse Spermatogenesis

Frontiers in Veterinary Science, 2021
Mammalian spermatogenesis is a highly ordered process that is determined by chromatin-associated moderators which still remain poorly understood. Through a multi-control group proteomics strategy, we confirmed that Sugp2 was a chromatin-associated ...

In vivo functions of miRNAs in mammalian spermatogenesis

Frontiers in Cell and Developmental Biology, 2023
MicroRNAs (miRNAs) are believed to play important roles in mammalian spermatogenesis mainly because spermatogenesis is more or less disrupted when genes encoding key enzymes for miRNA biogenesis are mutated.

Spermatogenesis in the boar [PDF]

Veterinary Quarterly, 1982
In order to study kinetics of the spermatogenic epithelium in the adult boar, a method has been developed to prepare seminiferous tubules mounted as a whole, after which these tubules have been processed and studied as described previously only for rats, mice and hamsters.

The Prmt5-Vasa module is essential for spermatogenesis in Bombyx mori.

PLoS Genetics, 2023
In lepidopteran insects, dichotomous spermatogenesis produces eupyrene spermatozoa, which are nucleated, and apyrene spermatozoa, which are anucleated.

Novel Gene Regulation in Normal and Abnormal Spermatogenesis

Cells, 2021
Spermatogenesis is a complex and dynamic process which is precisely controlledby genetic and epigenetic factors. With the development of new technologies (e.g., single-cell RNA sequencing), increasingly more regulatory genes related to spermatogenesis ...

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Proteostasis regulated by testis-specific ribosomal protein RPL39L maintains mouse spermatogenesis

iScience, 2021
Summary: Maintaining proteostasis is important for animal development. How proteostasis influences spermatogenesis that generates male gametes, spermatozoa, is not clear.

Designing Polymer Nanocomposites for X‐Ray Shielding: Mechanisms, Architectures, and Scalable Processing

Advanced Engineering Materials, EarlyView.
This review highlights advances in lightweight, lead‐free polymer nanocomposites for diagnostic X‐ray shielding. By linking filler chemistry, dispersion, architecture, and photon interaction mechanisms, it establishes structure–performance relationships guiding material design.
