Summary:【目的】克隆广西巴马小型猪孕激素和脂联素分子受体3(PAQR3)基因,并研究该基因在广西巴马小型猪不同组织中的表达特性,为揭示PAQR3的功能及其在疾病模型中的作用打下基础。【方法】采用RT-PCR扩增广西巴马小型猪PAQR3基因,应用在线预测软件对其功能和结构进行生物信息学分析,并以q RT-PCR分析PAQR3基因在不同组织中的表达特性及高脂高糖诱导后的表达水平。【结果】广西巴马小型猪PAQR3基因编码区(CDS)序列全长936 bp,编码312个氨基酸,与人类(XM_006714106.2)、猕猴(NM_001257693.1)、牛(XM_010806259.1)、家犬(XM_014109889.1)、家鼠(XM_006534874.2)、羊(XM_012180242.1)、鸡(XM_001233720.3)PAQR3氨基酸序列的一致性在81%以上,其中与猕猴的亲缘关系最近,与牛的亲缘关系相对较远。PAQR3蛋白氨基酸序列包含保守的Hly IⅡ结构域,为亲水性蛋白,有7个跨膜螺旋结构;其二级结构主要是延伸链,占31.83%;该蛋白不存在信号肽,不属于分泌蛋白。q RT-PCR分析结果表明,PAQR3基因在广西巴马小型猪的不同组织中均有表达,以在肺脏中的表达量最高、脂肪中的表达量最低;经高脂高糖诱导后,PAQR3基因在广西巴马小型猪肝脏组织中的表达水平显著降低(P〈0.05)。【结论】PAQR3基因在广西巴马小型猪不同组织中广泛表达,在胆固醇和甘油三脂充裕的条件下,机体可通过下调PAQR3基因的表达量来平衡胆固醇含量。

Guangxi Bama mini-pig; PAQR3 gene ; cloning; expression patterns analysis
[Objective]The present experiment was conducted to clone progesterone and adipoQ receptor 3 (PAQR3) gene of Guangxi Bama mini-pig and investigate its expresssion in different tissues of Guangxi Bama mini-pig, in order to lay a foundation for revealing PAQR3 fuction and its role in disease models. [Method]The PAQR3 gene of Guangxi Bama mini-pig was cloned by RT-PCR, the protein structure of porcine PAQR3 was analyzed based on bioinformatics using on- line prediction software. The PAQR3 gene expression pattern in different tissues and its expression level after being in- duced by high fat and high sugar were detected by qRT-PCR. [Result]The results showed that, the PAQR3 gene of Guangxi Bama mini-pig was 936 bp in length,
