水牛水通道蛋白8基因克隆及表达分析

Abstract

Abstract: In this study, buffalo AQP8 gene was cloned and its eukaryotic expression vector was constructed, the expression pattern of AQP8 gene in buffalo ovary tissue was also assayed. The results showed that the CDS length of cloned buffalo AQP8 gene was 732 bp, and it shared 100% homology of amino acid sequence with cattle and mouse. AQP8 protein was detected in different developmental stages of buffalo follicles, it had significantly higher expression in the secondary follicles than that of in the primordial and the primary follicles (P＜0.05), and it mainly expressed in the granulosa cells of the secondary follicles. Clear EGFP green fluorescent was observed in transfected cell groups with transfection of the pEGFP-N1-AQP8 eukaryotic expression plasmid into HEK293T cells by Lipofectamine^R LTX and PLUS^TM reagent. The above results lay foundation to further investigate the function of AQP8 gene in the buffalo follicle development and granulosa cell apopotosis.

Key words: buffalo; aquaporin 8; follicle; granulosa cells
