Abstract:
[Objective]To investigate the dynamic expression profiles and potential regulatory mechanisms of long non-coding RNAs(lncRNAs)in male reproductive system aging.[Methods]A naturally aging C57BL/6 mouse model was used and 4 mice were selected each at 3,15,and 21 months of age.RNA was extracted from seven regions of the male reproductive tract(testis,efferent duct,initial segment of epididymis,caput epididymis,corpus epididymis,cauda epididymis,and vas deferens),followed by RNA sequencing and bioinformatics analysis.[Results]Region-specific dynamic expression profiles of lncRNAs were constructed in the testis,epididymis(efferent duct,initial segment,caput,corpus,and cauda),and vas deferens of male mice.Combined with gene functional enrichment analysis,the functional associations of lncRNAs were elucidated in reproductive system aging.The differentially expressed lncRNAs in the aging testis were primarily involved in hormone biosynthesis and extracellular matrix organization,while those in the initial segment of the epididymis were closely related to cell recognition and epithelial cell migration.A comprehensive lncRNA expression atlas associated with male reproductive aging was established.[Conclusion]LncRNAs may participate in male reproductive aging through the regulation of the reproductive microenvironment,which provides key molecular targets and a research foundation for understanding age-related fertility decline.
