Abstract

Emerging evidence has demonstrated that N -methyladenosine (m A) and long noncoding RNAs (lncRNAs) are both crucial regulators in gastric cancer (GC) tumorigenesis. However, the interaction of m A and lncRNAs in GC progression are still unclear. Here, our team discovered that lncRNA LINC00958 expression up-regulated in GC tissue and cells. Clinically, high-expression of LINC00958 was clinically correlated to lower survival of GC patients. Functionally, in vitro assays demonstrated that LINC00958 promoted the GC cells' aerobic glycolysis. Mechanistically, methylated RNA immunoprecipitation sequencing (MeRIP-Seq) found that there were m A-modificated sites in LINC00958, and moreover m A methyltransferase KIAA1429 catalyzed the m A modification on LINC00958 loci. Moreover, LINC00958 interacted with GLUT1 mRNA via the m A-dependent manner to enhance GLUT1 mRNA transcript stability, thereby positively regulating the aerobic glycolysis of GC. In conclusion, our findings reveal the function and mechanism of KIAA1429-induced LINC00958 in GC, delineating novel understanding of m A-lncRNA in cancer biology.

摘要

越来越多的证据表明,N-甲基腺苷(m A)和长非编码 RNA(lncRNA)都是胃癌(GC)发生过程中的关键调节因子。然而,m A 和 lncRNA 在 GC 进展中的相互作用尚不清楚。在这里,我们的团队发现 lncRNA LINC00958 在 GC 组织和细胞中表达上调。临床上,LINC00958 的高表达与 GC 患者生存率降低相关。功能上,体外实验表明 LINC00958 促进了 GC 细胞的有氧糖酵解。机制上,甲基化 RNA 免疫沉淀测序(MeRIP-Seq)发现 LINC00958 中有 m A 修饰位点,并且 m A 甲基转移酶 KIAA1429 催化 LINC00958 位点的 m A 修饰。此外,LINC00958 通过 m A 依赖性方式与 GLUT1 mRNA 相互作用,增强 GLUT1 mRNA 转录稳定性,从而正向调节 GC 的有氧糖酵解。总之,我们的研究结果揭示了 KIAA1429 诱导的 LINC00958 在 GC 中的功能和机制,为 m A-lncRNA 在癌症生物学中的作用提供了新的认识。
