Abstract: Broiler ascites syndrome is a nutritional metabolic disease caused by multiple etiology,which is related to heredity,feeding management,nutritional imbalance and environment.Since its first appearance,the disease has caused serious economic losses to the global poultry industry.Research indicates that systemic hypoxia is an important cause of ascites in broilers.Prolonged hypoxia can lead to the injury of pulmonary artery endothelial cells (PAECs),resulting in functional disorders,excessive production of vasoactive factors,abnormal contraction of vascular smooth muscles,and exacerbation of abnormal proliferation,inflammatory responses,and phenotypic transformation of vascular endothelium. Over time,these changes will lead to complex pathological processes such as the thickening of the vascular media and the gradual narrowing of the lumen,which will promote pulmonary artery remodeling and eventually become the direct inducement of ascites formation.As epigenetic regulatory factors,miRNA plays an important role in regulating various signal transduction pathways and thus affecting cell physiological functions.In the formation of pulmonary hypertension,miRNA plays a particularly significant role in regulating the physiological process of pulmonary artery endothelial cells.Consequently,the author discussed the etiology and pathogenesis of broiler ascites syndrome,clarified the functional changes of pulmonary artery endothelial cells and the key role of miRNA in this complex disease process,in order to provide reference for the prevention and control of broiler ascites syndrome.

Key words: broiler ascites syndrome; pulmonary artery endothelial cells (PAECs); pulmonary hypertension; miRNA
