文摘为阐明鹅Calm1基因结构特征及其表达规律。克隆四川白鹅Calm1基因编码区序列并进行生物信息学分析,应用实时荧光定量PCR技术检测鹅不同等级卵泡和不同组织中Calm1基因的相对表达量。鹅Calm1基因编码区序列全长为450 bp,编码149个氨基酸,其氨基酸序列与原鸡相似性为99%。鹅大脑中Calm1表达量显著高于其他组织(P<0.05)。Calm1在不同等级卵泡组织中均有表达,F2级卵泡中Calm1表达量是小白卵泡(Small white follicles,SWF)的1.76倍(P<0.05),且显著高于F5、F4、F3和F1级卵泡(P<0.05);在排卵后卵泡(Postovulatory follicle,POF)组织中,POF1级卵泡组织中Calm1表达量显著高于POF2、POF3和POF4级卵泡(P<0.05);卵巢组织中Calm1的表达量,是小白卵泡的1.75倍(P<0.05)。Calm1是高度保守、广泛表达的蛋白质,Calm1可能通过影响卵泡细胞增殖和类固醇激素合成来参与调控动物繁殖。
