摘要 苏尼特羊(Ovis aries)是我国优质的肉羊资源,也是我国北方地区主要羊肉来源之一。长链非编码RNA (long non-coding RNA, LncRNA)在绵羊肌肉发育中发挥重要作用。为预测Lnc_000588在苏尼特羊骨骼肌发育中的调控网络,本研究对其在不同部位的组织表达量进行了实时荧光定量PCR分析及靶向miRNA-mRNA的生物信息学互作预测。同时,在小鼠(Mus musculus)成肌纤维细胞(C2C12)中检测了Lnc_000588的表达量。Lnc_000588在各组织中均有表达,且在背最长肌中的表达量极显著高于其他组织(P<0.01);Lnc_000588在C2C12细胞中的表达量随着细胞分化时间的延长而增加,48 h以后极显著高于较早时的表达(P<0.01)。;Lnc_000588可能通过miRNA参与调控肌肉的生长发育,其中的3个miRNA的靶基因富集于Ras信号通路(oas04014:Ras signaling pathway)、Rap1信号通路(oas04015:Rap1 signaling pathway)和AMPK信号通路(oas04152:AMPK signaling pathway)等66条通路。综上,Lnc_000588在苏尼特羊肌肉组织的表达量极显著高于其他组织,推测其参与了C2C12细胞分化。本研究为探究LncRNA参与苏尼特羊肌肉组织的调控功能提供了科学依据。

Abstract:Sunite sheep (Ovis aries) is high-quality mutton sheep resources in China and one of the main sources of mutton in northern China. Long non-coding RNA (LncRNA) plays an important role in muscle development in O. aries. To predict the regulatory network of Lnc_000588 in skeletal muscle development of Sunite sheep, in this study, the real-time quantitative PCR analysis was performed on its tissue expression in different parts, and the prediction of bioinformatics interaction of targeted miRNA-mRNA was carried out. Meanwhile, the expression of Lnc_000588 was detected in mouse (Mus musculus) C2C12 cells. Lnc_000588 was expressed in all tissues, and the expression level in the longissimus dorsi muscle was significantly higher than that in other tissues (P<0.01); there was no significant difference in Lnc_000588 during cell proliferation, and the expression level in C2C12 cells increased with the prolongation of differentiation time and the increase of myotubes, the expression after 48 h was extremely significantly higher than that in the earlier period (P<0.01). From Lnc_000588 involved in the regulation of the muscle growth and development through miRNA, a total of 32 miRNAs were predicted, of which 3 miRNAs were found to be related with muscle development. The target genes of these 3 miRNAs are enriched in the Ras signaling pathway (oas04014: Ras 66 pathways including), Rap1 signaling pathway (oas04015: Rap1 signaling pathway) and AMPK signaling pathway (oas04152: AMPK signaling pathway). In conclusion, the expression level of Lnc_000588 in Sunite sheep muscle tissue was significantly higher than that in other tissues, which may be involved in the differentiation of C2C12 cells. This study provides basic data for exploring the regulatory function of LncRNA involved in the muscle tissue of Sunite sheep.
