N6-methyladenosine (m6A) is the most abundant RNA modification in eukaryotes, and it participates in the regulation of pathophysiological processes in various diseases, including malignant tumors, by regulating the expression and function of both coding and non-coding RNAs (ncRNAs). More and more studies demonstrated that m6A modification regulates the production, stability, and degradation of ncRNAs and that ncRNAs also regulate the expression of m6A-related proteins. Tumor microenvironment (TME) refers to the internal and external environment of tumor cells, which is composed of numerous tumor stromal cells, immune cells, immune factors, and inflammatory factors that are closely related to tumors occurrence and development. Recent studies have suggested that crosstalk between m6A modifications and ncRNAs plays an important role in the biological regulation of TME. In this review, we summarized and analyzed the effects of m6A modification-associated ncRNAs on TME from various perspectives, including tumor proliferation, angiogenesis, invasion and metastasis, and immune escape. Herein, we showed that m6A-related ncRNAs can not only be expected to become detection markers of tumor tissue samples, but can also be wrapped into exosomes and secreted into body fluids, thus exhibiting potential as markers for liquid biopsy. This review provides a deeper understanding of the relationship between m6A-related ncRNAs and TME, which is of great significance to the development of a new strategy for precise tumor therapy.
N6-甲基腺苷(m6A)是真核生物中最丰富的 RNA 修饰,它通过调节编码和非编码 RNA(ncRNA)的表达和功能,参与多种疾病的病理生理过程的调节,包括恶性肿瘤。越来越多的研究表明,m6A 修饰调节 ncRNA 的产生、稳定性和降解,ncRNA 也调节 m6A 相关蛋白的表达。肿瘤微环境(TME)是指肿瘤细胞的内部和外部环境,由许多肿瘤基质细胞、免疫细胞、免疫因子和炎症因子组成,与肿瘤的发生和发展密切相关。最近的研究表明,m6A 修饰与 ncRNA 之间的串扰在 TME 的生物学调节中起着重要作用。在这篇综述中,我们从多个角度总结和分析了 m6A 修饰相关 ncRNA 对 TME 的影响,包括肿瘤增殖、血管生成、侵袭和转移以及免疫逃逸。我们表明,m6A 相关 ncRNA 不仅可以预期成为肿瘤组织样本的检测标志物,还可以包裹在外泌体中并分泌到体液中,从而显示出作为液体活检标志物的潜力。这篇综述提供了对 m6A 相关 ncRNA 与 TME 之间关系的更深入理解,这对开发新的肿瘤精准治疗策略具有重要意义。
