长链非编码RNA对肿瘤发生调控的研究进展

Regulatory Effects of Long Non-coding RNA on Tumorigenesis

长链非编码RNA(LncRNA)在肿瘤的发生发展过程中可能扮演着非常重要的角色,许多研究正逐步揭示这种复杂的基因表达调控和转录干预作用。然而,这种方式的体现却是多样的。目前发现,LncRNA可能存在蛋白质修饰、染色体重构、促进或是抑制靶基因表达、转录调控因子干预、表观遗传学修饰、天然反转录子作用以及一些目前尚未得知的方式来影响着肿瘤的发生。本文总结了相关研究进展,以期更好地探索LncRNA对肿瘤发生发展的作用。

Long non-coding RNAs（ LncRNA） may play a key role in tumorigenesis by regulating gene expression and intervening transcription. Recent studies have demonstrated that a series of patterns including protein modification,chromosomal reconstruction,regulation of target gene expression,transcription intervention,epigenetic modification,and natural antisense transcript are involved in this process. This article reviews recent research advances in this aspect with an attempt to better understand the role of LncRNA in tumorigenesis.
