Embryonic Cadaverine Signaling: Implications for Plasma Free Amino Acid and Skeletal Muscle Energy Metabolism in Newly Hatched Chicks.
Cadaverine is a bioactive substance derived from lysine degradation by lysine decarboxylase and has gained attention for its physiological effects. Studies in rodents have revealed its role as a cell growth regulator, particularly intestinal bacterial-produced cadaverine. However, the nutritional and physiological roles of cadaverine during the embryonic period remain unclear, especially considering the immature state of the gut microbiota and digestive functions during this stage. This study explored the potential functions of cadaverine as a nutritional and metabolic signal during chicken embryonic development. Experiments were conducted using an in ovo administration method to evaluate the effects of nutritional bioactive substances on developing chicken embryos. Although there were no observable changes in body or organ weights of newly hatched chicks following in ovo cadaverine administration to day 18 chick embryos, plasma tryptophan, Nτ-methylhistidine, and Nπ-methylhistidine concentrations decreased and the gene expression of insulin/insulin-like growth factor 1 signaling in skeletal muscle was upregulated. These findings imply that cadaverine influences tryptophan metabolism and skeletal muscle catabolism during the embryonic period, suggesting its role as a bioactive factor contributing to energy metabolism signaling in skeletal muscle.
期刊介绍:
The Journal of Poultry Science will publish original reports and reviews which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: breeding and genetics, nutrition and feeds, physiology, reproduction, immunology, behavior, environmental science, management and housing welfare, processing and products, and health in poultry. Submission of original articles to the Journal is open to all poultry researchers. The review articles are invited papers written by international outstanding researchers. Articles will be published in English, American style.
