MicroRNA (miRNA) in Plasma Small Extracellular Vesicles (sEV) as Potential Early Indicators of Dairy Cow Subfertility. [PDF]

J Extracell Biol
ABSTRACT Pregnancy and live birth rates are commonly used metrics to define fertility in humans and animals. The impact of aberrant microRNA (miRNA) expression on fertility‐related genes represents a significant knowledge gap in understanding post‐transcriptional regulatory mechanisms associated with reproductive dysfunction.

Trisomy 26 in a Holstein calf with disorders of sex development. [PDF]

Anim Genet
Abstract Hypospadias occurs sporadically in male livestock and is characterized by a non‐fused urethra during fetal development. In this study, perineal hypospadias, a bifid scrotum, penile hypoplasia, and bilateral abdominal cryptorchidism were diagnosed in a neonatal Holstein male calf.

Maternal Undernutrition Alters Fetal Muscle Growth, Metabolism, and Transcriptomic Regulation in Intrauterine Growth Restricted Sheep

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Maternal undernutrition in late pregnancy restricts fetal skeletal muscle growth and shifts muscle fiber types to fast muscle types. These changes are driven by changes in mitochondrial enzymes and DNA, endoplasmic reticulum stress, and ribosomal activity that predispose postnatal offspring to metabolic disorders.

The Oxytocin Receptor in Spermatozoa May Originate From Both Spermatogenesis and Epididymal Maturation, and Regulates Capacitation

Andrology, Volume 14, Issue 3, Page 747-765, March 2026.
Abstract Background The oxytocin receptor (OR) is a G‐protein‐coupled receptor recently identified in human spermatozoa, whose origin and role in sperm physiology remain unknown. Objectives In this study, using the pig as a model, we examine the presence of the OR in ejaculated spermatozoa through immunofluorescence and immunoblotting, and investigate ...

Improved taxonomic and gene sampling advance the knowledge of deep relationships within Macrodasyida (Gastrotricha)

Cladistics, Volume 42, Issue 1, Page 25-45, February 2026.
Abstract Advances in Macrodasyida (Gastrotricha) phylogenetics, fuelled by new species discoveries and molecular data, are reshaping taxonomic classifications. Molecular analyses suggest polyphyly in Cephalodasyidae and Macrodasyidae, yet insufficient sampling continues to obscure precise relationships.

Literature horizon scan for new scientific data on plants, microorganisms and animals, and their products obtained by new genomic techniques (October 2025)

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract The European Food Safety Authority has issued several scientific opinions on plants, microorganisms and animals obtained through certain new genomic techniques (NGTs), following requests received by the European Commission. These scientific opinions provided considerations on the potential risks associated with NGTs, as compared to ...

An Increase in Male Recombination Rate With Age in Dairy Cattle Is Heritable and Polygenic

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 35-49, January 2026.
ABSTRACT Meiotic recombination is an essential process for shuffling genetic diversity in sexually reproducing organisms, can vary within and between individuals in response to intrinsic and extrinsic factors, and can be heritable. Interestingly, recombination rate has been found to vary with age in some species, but to date, there have been no ...

Beyond the Binary: Controlling Natural Sex‐Change in Hermaphroditic Fishes

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Sex‐change in hermaphroditic fishes is a complex but natural biological phenomenon that has significant implications for aquaculture fingerling production, selective breeding, and grow‐out. Understanding the physiological, endocrinological, and molecular pathways underlying hermaphroditism in fishes offers unique opportunities to manipulate ...

New developments in biotechnology applied to animals: An assessment of the adequacy and sufficiency of current EFSA guidance for animal risk assessment

EFSA Journal, Volume 23, Issue 8, August 2025.
Abstract EFSA was requested by the European Commission to provide a scientific opinion on new developments in biotechnology, including new genomic techniques, as applied to animals for food, feed and other agricultural uses. A horizon‐scanning exercise identified a variety of animals obtained with new genomic techniques, with the potential to reach the

Advances in CRISPR‐Cas9 in lineage tracing of model animals

Animal Models and Experimental Medicine, Volume 8, Issue 6, Page 1004-1022, June 2025.
Cell lineage tracing is a key technology for describing the developmental history of individual progenitor cells and assembling them to form a lineage development tree. However, traditional methods have limitations of poor stability and insufficient resolution.
