CircRNAs are a superabundant and highly conserved group of noncoding RNAs (ncRNAs) that are characterized by their high stability and integrity compared with linear forms of ncRNAs. Recently, their critical role in gene expression regulation has been shown; thus, it is not far‐fetched to believe that their abnormal expression can be a cause of different kinds of diseases such as cancer, neurodegenerative, and autoimmune diseases. They can have a function in variety of biological processes such as microRNA (miRNA) sponging, interacting with RNA‐binding proteins, or even an ability to translate to proteins. A huge challenge in finding diagnostic biomarkers is finding noninvasive biomarkers that can be detected in human fluids, especially blood samples. CircRNAs are becoming candidate biomarkers for diagnosis and prognosis of these diseases through their ability to transverse from the blood‐brain barrier and their broad presence in circulating exosomes. The circRNA for miRNA‐7 (ciRS‐7) is newly recognized, and acknowledged to being related to human pathology and cancer progression. In this review, we first briefly summarize the latest studies about their characteristics, biogenesis, and their mechanisms of action in the regulation and development of human diseases. Finally, we provide a list of diseases that are linked to one member of this novel class of ncRNAs called ciRS‐7.

CDR1-AS 在癌症和人类疾病的调控和发展中的作用不断扩大。

CircRNA 是一组超丰富且高度保守的非编码 RNA (ncRNA),与线性形式的 ncRNA 相比,其特点是具有高稳定性和完整性。最近,它们在基因表达调控中的关键作用已被证实。因此,相信它们的异常表达可能是导致癌症、神经退行性疾病和自身免疫性疾病等不同疾病的原因并不牵强。它们可以在各种生物过程中发挥作用,例如 microRNA (miRNA) 海绵化、与 RNA 结合蛋白相互作用,甚至具有翻译成蛋白质的能力。寻找诊断生物标志物的一个巨大挑战是寻找可以在人体体液,尤其是血液样本中检测到的非侵入性生物标志物。circRNAs 正成为这些疾病诊断和预后的候选生物标志物,因为它们能够穿过血脑屏障并广泛存在于循环外泌体中。miRNA-7(ciRS-7)的circRNA是新发现的,并被认为与人类病理学和癌症进展有关。在这篇综述中,我们首先简要总结了关于它们的特征、生物发生及其在人类疾病调控和发展中的作用机制的最新研究。最后,我们提供了一系列疾病,这些疾病与称为 ciRS-7 的这种新型 ncRNA 的一个成员有关。并承认与人类病理学和癌症进展有关。在这篇综述中,我们首先简要总结了关于它们的特征、生物发生及其在人类疾病调控和发展中的作用机制的最新研究。最后,我们提供了一系列疾病,这些疾病与称为 ciRS-7 的这一新型 ncRNA 的一个成员相关。并承认与人类病理学和癌症进展有关。在这篇综述中,我们首先简要总结了关于它们的特征、生物发生及其在人类疾病调控和发展中的作用机制的最新研究。最后,我们提供了一系列疾病,这些疾病与称为 ciRS-7 的这一新型 ncRNA 的一个成员相关。
