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.
