摘要: 为了研究鹅FoxO1(forkhead box O1)基因的功能,根据GenBank已收录的鸡(Gallus gallus)、人(Homo sapiens)和小鼠(Mus musculus)等物种FoxO1基因序列的同源保守区域,设计特异性引物,利用RT-PCR技术克隆鹅FoxO1基因cDNA序列,并对基因序列进行了生物信息学分析。结果表明,成功克隆得到了鹅FoxO1基因cDNA序列,通过BLAST比对,鹅FoxO1基因与原鸡、人、小鼠的核苷酸序列同源性分别为97%、83%、82%,FoxO1基因在四川白鹅中表达水平总体表现为:皮脂>腹脂>腿肌>胸肌>肝脏。因此,FoxO1基因在多个组织中都有表达,且表达差异较大。

Abstract: In order to study the function of goose forkhead box O1 (FoxO1) gene, in this study, according to the highly conservative region of FoxO1 gene sequences from chicken (Gallus gallus),human (Homo sapiens),and mouse (Mus musculus)in the GenBank,the specific primers were designed to clone the CDS region of goose FoxO1 gene using the RT-PCR method,and the bioinformatics analyses of FoxO1 were conducted.The results showed that the full length of CDS region of FoxO1 gene was obtained, and the similarities of nucleotide sequence of goose with chicken, human and mouse were 97%, 83%, 82%, respectively. The expression level of FoxO1 gene in various tissues of Sichuan White goose showed: sebum> abdominal fat > crureus > pectorales > liver. In conclusion, FoxO1 gene could be expressed in several tissues, and showed an evident expression difference.
