环状RNA的生物学功能及其在胃肠肿瘤发生中的作用

环状RNA(circular RNA,circ RNA)是广泛存在于真核生物转录组的内源性非编码RNA.与线性RNA不同,circ RNA不易被酶解,具有更加稳定的结构.circ RNA具有微小RNA(micro RNA,mi RNA)海绵、RNA结合蛋白海绵、调节转录以及翻译蛋白质等多种生物学功能,能够在转录水平或转录后水平调节基因的表达.近期的研究发现,circ RNA在调控肿瘤细胞增殖、迁移和侵袭过程中扮演着重要的角色.胃肠肿瘤是我国常见且死亡率高的恶性肿瘤,研究者在胃肠肿瘤中发现大量异常表达的circ RNA(如:hsa_circ_0014717、hsa_circ_0001017、hsa_circ_0061276、hsa_circ_0125965和hsa_circ_KLDHC10等).本文首先阐述circ RNA的形成机制和生物学功能;然后结合国内外胃肠肿瘤相关circ RNA的最新研究进展和本课题组相关研究成果,对circ RNA影响胃肠肿瘤发生的机制作一综述,并希望能以此为胃肠肿瘤的诊断和治疗提供新的理论依据.
