MICALIS Institute's ANAXEM platform joins SAPS!

The Anaxem experimental unit is an animal facility for rodents and birds, either germ-free or with controlled microbiota, kept in sterile isolators. It provides research teams from Institut Micalis, INRAE and other organizations (academic and private) with animals, infrastructure and technical assistance to carry out protocols on the dialogue between the commensal microbiota and its host.

A major article on the origin and precise dating of the domestication of Equus caballus 4200 years ago in the Don Valley.

Tous les chevaux domestiques vivant sur terre, qu'ils soient champions de courses ou compagnons de club équestre, trouvent leurs origines dans la vallée du Don au sud-ouest de la Russie, mais la chronologie exacte de leur intégration généralisée dans les sociétés humaines divise encore la communauté scientifique. Une étude publiée le 6 juin dans la revue Nature démontre que l’essor des chevaux domestiques n’a commencé qu’il y a 4 200 ans environ. Cette date marque une nouvelle ère dans l'histoire humaine où les chevaux ont révolutionné la vitesse des déplacements et des échanges entre les peuples. Ces recherches ont été coordonnées par une équipe du CNRS et de l’université Toulouse III – Paul Sabatier dirigée par Ludovic Orlando au sein du Centre d’anthropobiologie et de génomique de Toulouse1 et impliquent 133 scientifiques, issus de 113 institutions à travers le monde.

In vivo exploration of the infectious processes of spring viraemia virus of carp (SVCV): an integrated approach from model organism to target species.

Aquaculture is the fastest-growing food production sector, albeit hampered by environmental and ecological crises and epidemics. Carp spring viraemia virus (CSVV) is a notifiable pathogen of major interest, for which there is no vaccine, and whose disease can be modeled in zebrafish (ZF).

14th International Havemeyer Foundation Horse Genome Workshop a great success

The 14th Havemeyer Horse Genome Workshop was held from May 12 to 15, 2024 at the University of Caen, bringing together an international community of 110 people to share scientific results on the horse genome. A resounding success that will undoubtedly raise the international profile of INRAE, the GABI unit, LABÉO, the city of Caen and the Normandy region.

SOCS2 mutation induces structural and functional changes in mammary gland development.

Lactation is an essential process for mammals. In sheep, the R96C mutation in the SOCS2 (Suppressor Of Cytokine Signaling 2) protein is associated with higher milk production and increased susceptibility to mastitis. To understand the involvement of the R96C mutation in mammary gland development and lactation, we developed a mouse model carrying this mutation (SOCS2KI/KI).

Sélection et dynamique de la diversité génétique chez la truite arc-en-ciel

Any animal or plant population, wild or domesticated, evolves through continuous and cumulative changes over time, based on various evolutionary forces, namely selection, genetic drift, mutation and migration, with relative effects that depend on population history and structure. The footprints left along the genome by these evolutionary processes may correspond to positive selection of favorable alleles, resulting in highly homozygous regions with low genetic diversity, or, on the contrary, to balancing selection phenomena enabling regions to be maintained in a heterozygous state and thus with high genetic diversity.

Select trout that are more resistant to heat waves

Climate change is already causing, and will continue to cause, more and more heat waves. These heat waves have a negative effect on water quality in aquaculture farms: higher temperatures and lower levels of available oxygen in the water. Technical solutions are available to limit these sometimes rapid and severe variations in temperature and oxygenation in trout farms, but they are often costly. Selecting animals that can withstand these heat waves is therefore a promising way of coping with the impact of climate change. Scientists at INRAE, in collaboration with SYSAAF (the French poultry and aquaculture breeders' association) and two French trout breeding companies, have studied the feasibility of breeding for resistance to hyperthermia (exposure to high temperatures) and/or hypoxia (exposure to reduced oxygen levels).

Prestigious AAAS award for the study of ancient DNA in Native American horses

The prestigious Newcomb Cleveland 2024 prize awarded for a publication on the ancient DNA of horses bred and used by indigenous peoples of the North American plains, published in the journal Science in 2023. An interdisciplinary team of American Indian and Western scientists, coordinated by Ludovic Orlando (CNRS Toulouse) and William Timothy Treal Taylor (University of Colorado), has been selected to receive the Newcomb Cleveland 2024 Award (AAAS) for their work on the genetic origins of the first horses bred and used by the indigenous peoples of the North American plains.

A high-fat maternal diet alters the composition of the embryonic microenvironment and induces an embryonic sex-specific gene response as early as the pre-implantation stage.

Over the last few decades, eating habits have changed and fat consumption has increased. Combined with low energy expenditure, excessive fat intake contributes to an increase in metabolic diseases that now affect young populations of childbearing age. This study explored the impact of a high-fat maternal diet on the embryo prior to implantation in the uterus, using the rabbit as a model animal. This work is published in Journal of Developmental Origins of Health and Disease.

Understanding pig embryo development: an asset for breeding tomorrow's animals

In a study published in Genomics, scientists from the UMR Génétique Animale et Biologie Intégrative - GABI (INRAE/AgroParisTech/UPSaclay, Jouy-en-Josas) have characterized the transcriptome of 35,000 embryonic cells derived from pig embryos between 5 and 11 days after fertilization. They were able to identify new sub-populations of embryonic cells, both for the secretion of molecules required for implantation, such as those expressing interleukin 1 beta (IL1B), and a population of stem cells expressing LRP2, which will subsequently contribute to the development of the embryonic placenta.
