The dynamic expression of YAP is essential for the development of male germ cells derived from human embryonic stem cells

Scientific Reports
YAP plays a vital role in controlling growth and differentiation in various cell lineages. Although the expression of YAP in mice testicular and spermatogenic cells suggests its role in mammalian spermatogenesis, the role of YAP in the development of ...

When proteases reshape barriers: Basement membrane remodelling in development, wound healing and tumour progression

The FEBS Journal, EarlyView.
Basement membrane (BM) homeostasis relies on a balance between integrity, controlled remodelling and pathological degradation. Increased protease expression beneath the BM, along with reduced levels of endogenous protease inhibitors, drives the transition from a continuous, protective barrier to a discontinuous interface.

Cryopreservation and culture strategies for testicular tissue and cells in small and large animals

Frontiers in Veterinary Science
The preservation of testicular tissue and male germ cells represents a cutting-edge technique for safeguarding fertility, especially when sperm collection is not possible, such as in prepubertal animals, those that die unexpectedly or that receive ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

New Insights into D-Aspartate Signaling in Testicular Activity

Cells
D-aspartate (D-Asp) is an amino acid found in high concentrations in the testis and pituitary gland. Increasing evidence suggests that D-Asp promotes spermatogenesis by activating testosterone production in the Leydig cells via LH release from the ...

Ivermectin Toxicity in Humans and Animals: Clinical Spectrum, Mechanisms, and Management

Journal of Applied Toxicology, Volume 46, Issue 6, Page 1856-1870, June 2026.
ABSTRACT Ivermectin is a widely used macrocyclic lactone with established efficacy against a broad range of parasitic infections in humans and animals and a long‐standing reputation for clinical safety. However, increasing evidence indicates that ivermectin can produce clinically relevant toxicity under specific conditions, particularly involving the ...

Sequence and structural alignments reveal insights into ANKLE2 evolution and function

Protein Science, Volume 35, Issue 6, June 2026.
Abstract ANKLE2 is an enigmatic protein with emerging roles in cell division, development, and virus replication. While ANKLE2 orthologs are present in all animals, its domain composition has evolved over time. ANKLE2's two namesake domains, the ankyrin repeat and LEM domains (named for LAP2, Emerin, and MAN1), have clear and defined roles; however ...

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

Advanced Science, Volume 13, Issue 26, 8 May 2026.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...
