Stage‐Resolved Phosphoproteomic Landscape of Mouse Spermiogenesis Reveals Key Kinase Signaling in Sperm Morphogenesis [PDF]

Advanced Science
Spermiogenesis is the committed step of sperm production, during which spermatid cells undergo dramatic morphological transformations and transcriptional silencing.

Systematic evaluation of scallop (Argopecten irradians) SoxH reveals its crucial role in spermiogenesis with limited evidence for sex determination [PDF]

Communications Biology
The transcription factor Sox30 (SoxH), a conserved regulator of vertebrate spermatogenesis, remains poorly characterized in mollusks, despite emerging evidence of its potential role in sex regulation.

Description of the Seminiferous Epithelium Cycle Stages in the Zebra Finch Taeniopygia guttata [PDF]

Animals
Spermatogenesis in passerine birds remains poorly characterized. Previous studies focused on the steps of spermiogenesis, while a detailed staging of the seminiferous epithelium cycle is still lacking for this order.

ELAPOR1 mediated vesicle traffic is required for acrosome biogenesis and male fertility in mice [PDF]

Cellular and Molecular Life Sciences
Spermiogenesis is the post-meiotic differentiation and morphological change of the haploid spermatids. Acrosome biogenesis is one of the key events of spermiogenesis, which generates a specialized membranous organelle crucial for shaping the balanced ...

Insights into the Mechanism of Bovine Spermiogenesis Based on Comparative Transcriptomic Studies

Animals, 2021
To reduce subfertility caused by low semen quality and provide theoretical guidance for the eradication of human male infertility, we sequenced the bovine transcriptomes of round, elongated spermatids and epididymal sperms.

Regulation of Miwi-mediated mRNA stabilization by Ck137956/Tssa is essential for male fertility

BMC Biology, 2023
Background Sperm is formed through spermiogenesis, a highly complex process involving chromatin condensation that results in cessation of transcription.

Autophagy regulates plastid reorganization during spermatogenesis in the liverwort Marchantia polymorpha

Frontiers in Plant Science, 2023
Autophagy is a highly conserved system that delivers cytoplasmic components to lysosomes/vacuoles. Plastids are also degraded through autophagy for nutrient recycling and quality control; however, the involvement of autophagic degradation of plastids in ...

Dynamic rearrangement and autophagic degradation of mitochondria during spermiogenesis in the liverwort Marchantia polymorpha

Cell Reports, 2022
Summary: Mitochondria change their morphology in response to developmental and environmental cues. During sexual reproduction, bryophytes produce spermatozoids with two mitochondria in the cell body.

Association of the ubiquitin specific peptidase 9X -linked and Afadin expression patterns with sexual maturation in boar testis

Journal of Animal Science and Technology, 2021
Closely correlated expression patterns between ubiquitin specific peptidase 9X-linked (USP9X) and adherens junction formation factor (Afadin) in mouse testis development suggests that Usp9x regulates the ...

Broad phosphorylation mediated by testis-specific serine/threonine kinases contributes to spermiogenesis and male fertility

Nature Communications, 2023
Genetic studies elucidate a link between testis-specific serine/threonine kinases (TSSKs) and male infertility in mammals, but the underlying mechanisms are unclear.
