Abstract

Circular RNAs are covalently closed and non-coding in eukaryotes, which have tissue- specific and temporal-specific expression patterns whose biogenesis is regulated by transcription and splicing. Most circular RNAs are localized in the cytoplasm. The sequences and protein-binding elements of circular RNAs facilitate circular RNAs in exerting biological functions through complementary base pairing, regulating protein function or self-translation. Recent studies have revealed that N6-Methyladenosine (m6A), a prevalent post-transcriptional modification, can affect the translation, localization, and degradation of circular RNAs. Cutting-edge research into circular RNAs have benefitted from the development of high-throughput sequencing technology. Furthermore, the expansion of novel research methods has promoted progress into circular RNA research.

环状rna的生物发生、生物学功能和修饰
环状RNA在真核生物中是共价封闭的和非编码的,具有组织特异性和时间特异性的表达模式,其生物发生由转录和剪接调节。大多数环状RNA定位在细胞质中。环状RNA的序列和蛋白质结合元件促进环状RNA通过互补碱基配对、调节蛋白质功能或自翻译发挥生物功能。最近的研究表明,N6-甲基腺苷(m6A)是一种普遍存在的转录后修饰,可以影响环状RNA的翻译、定位和降解。对环状RNA的前沿研究得益于高通量测序技术的发展。此外,新研究方法的扩展促进了环形RNA研究的进展。

期刊介绍: Under new editorial leadership, Experimental and Molecular Pathology presents original articles on disease processes in relation to structural and biochemical alterations in mammalian tissues and fluids and on the application of newer techniques of molecular biology to problems of pathology in humans and other animals. The journal also publishes selected interpretive synthesis reviews by bench level investigators working at the "cutting edge" of contemporary research in pathology. In addition, special thematic issues present original research reports that unravel some of Nature''s most jealously guarded secrets on the pathologic basis of disease. Research Areas include: Stem cells; Neoangiogenesis; Molecular diagnostics; Polymerase chain reaction; In situ hybridization; DNA sequencing; Cell receptors; Carcinogenesis; Pathobiology of neoplasia; Complex infectious diseases; Transplantation; Cytokines; Flow cytomeric analysis; Inflammation; Cellular injury; Immunology and hypersensitivity; Athersclerosis.
