Seminal Plasma Modifies the Transcriptional Pattern of the Endometrium and Advances Embryo Development in Pigs

Frontiers in Veterinary Science, 2019
Background: Seminal plasma (SP) promotes sperm survival and fertilizing capacity, and potentially affects embryo development, presumably via specific signaling pathways to the internal female genital tract.Objectives: This study evaluated how ...

Generation of Cloned Sheep Lacking Galactose‐α1,3‐Galactose and N‐Glycolylneuraminic Acid Antigens

Xenotransplantation, Volume 33, Issue 3, May/June 2026.
ABSTRACT Livestock have long been regarded as a potential source of donor organs to alleviate the global organ shortage for transplantation. Sheep have a similar anatomy to humans, providing the standard model for demonstrating biocompatibility and performance of biological heart valves to obtain regulatory approval for their use in transplantation ...

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 ...
