摘要:

为探究AGBL5在双峰驼睾丸及附睾组织中的表达及分布规律,及对季节性繁殖的调控作用,基于转录组学筛选的差异基因AGBL5,以发情期、乏情期双峰驼睾丸及附睾组织为材料,通过H&E染色、免疫荧光(IF)、实时荧光定量PCR(qRT-PCR)和蛋白免疫印迹(Western Blot)等方法,检测睾丸及附睾不同发育时期AGBL5基因的表达情况。测序结果显示,AGBL5基因的mRNA水平在乏情期睾丸组织中高表达;H&E结果显示,发情期睾丸组织生精小管管腔大于乏情期,有大量精细胞存在,发情期附睾管壁较厚,乏情期则相反,发情期和乏情期都能观察到精细胞的存在;在附睾组织中,发情期的附睾管壁厚度增加,且周围结缔组织呈现疏松状态;乏情期的附睾管壁厚度变薄,结缔组织则较为致密,同时附睾尾管腔内可见大量精细胞积聚;qRT-PCR结果显示,在睾丸组织中,乏情期AGBL5基因的mRNA表达水平极显著高于发情期;在附睾组织中,乏情期附睾头及附睾尾中AGBL5基因的mRNA表达水平均显著高于发情期,而附睾体AGBL5基因的mRNA表达水平显著低于发情期;Western Blot结果显示,AGBL5蛋白表达量同mRNA表达趋势一致。IF结果显示,AGBL5蛋白在睾丸间质细胞、支持细胞、附睾上皮及平滑肌细胞中均存在不同程度荧光表达信号。综上所述,结果提示,AGBL5的差异表达,可能与睾丸的发育及精子的成熟过程密切相关,为进一步探究AGBL5参与雄性双峰驼季节性繁殖调控奠定数据基础。

Abstract:

To investigate the expression and distribution patterns of AGBL5 in the testis and epididymis tissues of Bactrian camels,as well as its regulatory role in seasonal reproduction,this study focused on AGBL5,a differentially expressed gene identified through transcriptomic screening,using tissues from the testis and epididymis of Bactrian camels during the breeding season and non-breeding season,using H&E staining,immunofluorescence(IF),Real-time Quantitative PCR(qRT-PCR)and Western Blot to examine the expression of the AGBL5 gene in testicular and epididymal tissues at different developmental stages.Sequencing results indicated that the AGBL5 gene was highly expressed at mRNA level in testicular tissue during the non-breeding season.H&E results showed that the lumen of the seminiferous tubules in testicular tissue was larger during the breeding season than during the non-breeding season,with a large number of spermatozoa present.The walls of the epididymal ducts were thicker during the breeding season,whereas the opposite was true during the non-breeding season.Spermatozoa were observed during both the breeding and non-breeding seasons;in epididymal tissue,the thickness of the epididymal duct walls increased during the breeding season,and the surrounding connective tissue appeared loose;during the non-breeding season,the epididymal duct walls were thinner and the connective tissue was denser,whilst a large accumulation of spermatozoa was visible within the lumen of the epididymal tail.qRT-PCR results showed that in testicular tissue,the mRNA expression level of the AGBL5 gene was significantly higher during the non-breeding season than during the breeding season.In epididymal tissue,the mRNA expression levels of the AGBL5 gene in both the head and tail of the epididymis were significantly higher during the non-breeding season than during the breeding season,while the mRNA expression levels in the body of the epididymis were significantly lower during the non-breeding season than during the breeding season.Western Blot results showed that AGBL5 protein expression levels were consistent with the trends observed for mRNA expression.IF results showed that the AGBL5 protein exhibited varying degrees of fluorescent expression signals in testicular interstitial cells,sertoli cells,epididymal epithelial cells and smooth muscle cells.In summary,the results suggest that the differential expression of AGBL5 may be closely related to testicular development and sperm maturation,laying a data foundation for further investigation into the role of AGBL5 in the regulation of seasonal reproduction in male Bactrian camels.
