摘要:

铁是动物体必需的微量元素,缺铁引发的贫血性疾病在新生动物中所占比例较大,缺铁性贫血是影响新生动物健康及其遗传生长潜力的关键环节。因此,开展改善缺铁性贫血的研究对动物健康具有重要科学意义。铁调素(Hepcidin)调节铁中心代谢、参与体内铁吸收与转运、调控铁营养对母体胎儿生长发育和新生动物铁代谢具有重要生物学意义。随着生物学技术的应用与发展,动物体内越来越多的铁调节蛋白被鉴定,但受限于母体血胎屏障和乳腺屏障,使Hepcidin对于母体-胎盘动物铁代谢的调节机制仍不清楚。本文就铁调素对动物机体铁代谢及妊娠铁营养相关研究进行综述,为后续从事此方面研究的同行提供参考或指出新的研究方向。

Abstract:

Iron is an essential trace element in animals. Iron deficiency-induced anemia disease accounts for a large proportion in newborn animals. Iron deficiency anemia is a key link that affects the health of newborn animals and their genetic growth potential. Therefore, research on iron deficiency anemia is of great scientific significance to animal health. Hepcidin regulates iron center metabolism, participates in iron absorption and transport in the body, and regulates iron nutrition, it has important biological significance for maternal and fetal growth and iron metabolism in newborn animals. With the application and development of biological technology, more and more iron regulatory proteins have been identified in animals, but restricted by the maternal blood-fetal barrier and the mammary barrier, hepcidin's regulation mechanism of maternal-placental iron metabolism is still unclear. By reviewing relative researches about the regulation of hepcidin on iron metabolism of animal body and iron nutrition in pregnancy, the paper aims to provide new research directions for colleagues in this field.

Key words: animal health, hepcidin, iron metabolism, iron, anemia, hypoxia
