[Abstract]:The first, second branchial arch is an important structure in the process of embryonic development, which can be divided into craniofacial and ear structures. The abnormal development of the branchial arch can lead to the structural malformation of the craniofacial and ear, such as zebrafish and rat. Forkhead (Fox) protein family is a key transcription factor in the process of embryonic development, the Foxi family has the corresponding degree of expression in different periods of embryonic ectental, mutation of foxi1 gene in zebrafish has jaws, ear plate deletion and branchial arch neural crest cell apoptosis and abnormal Foxi1 mutation, rats, dogs and other animal also a similar anomaly. Foxi protein may regulate the expression of related genes during the development of early embryo through the action of precursor factor, which affects the formation of the whole embryo craniofacial structure.

【正文快照】： 1前言鰓弓是胚胎發(fā)育中分化為顱面部骨骼的重要結(jié)構(gòu),尤其是第1、2鰓弓,其衍生物可形成耳、舌、上下頜骨等重要結(jié)構(gòu)。鰓弓的異常發(fā)育可造成胚胎顱面部骨骼畸形,合并耳、舌等器官缺陷。Fox蛋白家族是一系列轉(zhuǎn)錄因子家族,該蛋白的缺失可在斑馬魚、雞、鼠等動(dòng)物的發(fā)育過(guò)程中造成鰓，
