摘要:

为了深入地讨论牦牛ANXA5基因序列的特点,阐述其组织及细胞表达特性,通过采集牦牛不同组织样品,如心、肝、脾、肺、肾、子宫、卵巢、输卵管等,提取总RNA。采用PCR、生物信息学软件、实时荧光定量PCR、免疫组化等技术对牦牛ANXA5基因进行克隆、序列分析及表达特性研究。结果显示,牦牛ANXA5基因CDS区长为966 bp,共编码321个氨基酸。与黄牛比较,发现共有6个碱基突变存在于牦牛ANXA5基因中。黄牛与牦牛的核苷酸和氨基酸同源性大于99%,与其他哺乳动物进行氨基酸同源性比较,结果也均在90%以上,说明ANXA5基因在长期进化中保守。在牦牛的肺组织中,ANXA5基因表达量最高,与其他组织差异极显著(P<0.01);在子宫和输卵管组织中表达量次之。ANXA5在牦牛不同时期卵巢颗粒细胞中均有表达,且表达量随时间增长而逐渐升高。结果显示,培养72 h颗粒细胞中ANXA5表达量极显著高于培养24,36 h颗粒细胞(P<0.01);培养48 h颗粒细胞中ANXA5表达量极显著高于培养24 h颗粒细胞(P<0.01),显著高于培养36 h颗粒细胞(P<0.05),表明ANXA5在黄体化的颗粒细胞中表达量更高。然而,免疫组化结果显示,ANXA5的亚细胞定位于细胞质,在黄体细胞中表达较高。

Abstract:

In order to obtain the molecular characterization of the yak ANXA5 gene,discuss its expression characteristics in tissues and cells,and larify its medium localization in granulosa cells.Samples of yak heart,liver,spleen,lung,kidney,uterus,ovaries and oviducts were collected.After extraction of total RNA,we used PCR,bioinformatics software,qPCR techniques and immunocytochemistry to clone and analyze sequence of the yak ANXA5 gene and investigated its expression and localization.The results showed that the CDS region of the yak ANXA5 gene was 966 bp in length,encoding 321 amino acids.Compared to the cattle ANXA5 genes,there were 6 base mutations in the yak ANXA5 gene.Both the nucleotide homology and amino acid homology of yak and cattle were more than 99%,and the amino acid homology were more than 90% with other mammals,indicating that the ANXA5 gene was more conservative in evolution.ANXA5 expression level was highest in lung,which was extremely significant higher than the other tissues(P<0.01),followed by uterus and oviduct.ANXA5 was expressed in ovarian granulosa cells of yak at different stages,and the expression level increased gradually with time.The results showed that the expression level of ANXA5 in cultured 72 h granulosa cells were extremely significant higher than that in cultured 24,36 h granulosa cells(P<0.01).The expression level of ANXA5 in cultured 48 h granulosa cells were extremely significant higher than that in cultured 24 h granulosa cells(P<0.01)and significantly higher than that in cultured 36 h granulosa cells(P<0.05),indicating that the expression level of ANXA5 in luteinized granulosa cells was higher.However,the immunohistochemical results showed that the subcellular localization of ANXA5 was in the cytoplasm,and corpus luteum cells were highly expressed.
