. This study aimed to screen potential crucial lncRNAs and genes involved in aging. . The data of 9 peripheral white adipocytes, respectively, taken from male C57BL/6J mice (6 months, 14 months, and 18 months of age) in GSE25905 were used in this study. Differentially time series expressed lncRNA genes (DE-lncRNAs) and mRNA genes (DEGs) were identified. After cluster analysis of lncRNAs expression pattern, target genes of DE-lncRNAs were predicted from the DEGs, and functional analysis for target genes was conducted. . A total of 8301 time series-related DEGs and 43 time series-related DE-lncRNAs were identified. Among them, 41 DE-lncRNAs targeted 1880 DEGs. The DEGs positively regulated by DE-lncRNAs were mainly related to the development of blood vessel and the pathways of cholesterol biosynthesis and elastic fibre formation. Furthermore, the DEGs negatively regulated by DE-lncRNAs were correlated with protein metabolism. . These DE-lncRNAs and DEGs are potentially involved in the process of aging.
. 本研究旨在筛选与衰老相关的潜在关键长链非编码 RNA(lncRNA)和基因。. 使用 GSE25905 中分别来自雄性 C57BL/6J 小鼠(6 个月、14 个月和 18 个月)的 9 个外周白色脂肪细胞的数据进行了本研究。鉴定出差异时间序列表达的 lncRNA 基因(DE-lncRNAs)和 mRNA 基因(DEGs)。对 lncRNA 表达模式进行聚类分析后,从 DEGs 中预测 DE-lncRNA 的靶基因,并对靶基因进行功能分析。. 共鉴定出 8301 个与时间序列相关的 DEGs 和 43 个与时间序列相关的 DE-lncRNAs。其中,41 个 DE-lncRNA 靶向 1880 个 DEG。由 DE-lncRNA 正向调控的 DEGs 主要与血管发育以及胆固醇生物合成和弹性纤维形成途径相关。此外,由 DE-lncRNA 负向调控的 DEGs 与蛋白质代谢相关。. 这些 DE-lncRNAs 和 DEGs 可能参与了衰老过程。
