Extracellular vesicles (EVs) are defined as subcellular structures limited by a bilayer lipid membrane that function as important intercellular communication by transporting active biomolecules, such as proteins, amino acids, metabolites, and nucleic acids, including long non-coding RNAs (lncRNAs). These cargos can effectively be delivered to target cells and induce a highly variable response. LncRNAs are functional RNAs composed of at least 200 nucleotides that do not code for proteins. Nowadays, lncRNAs and circRNAs are known to play crucial roles in many biological processes, including a plethora of diseases including cancer. Growing evidence shows an active presence of lnc- and circRNAs in EVs, generating downstream responses that ultimately affect cancer progression by many mechanisms, including angiogenesis. Moreover, many studies have revealed that some tumor cells promote angiogenesis by secreting EVs, which endothelial cells can take up to induce new vessel formation. In this review, we aim to summarize the bioactive roles of EVs with lnc- and circRNAs as cargo and their effect on cancer angiogenesis. Also, we discuss future clinical strategies for cancer treatment based on current knowledge of circ- and lncRNA-EVs.
细胞外囊泡(EVs)被定义为受双层脂质膜限制的亚细胞结构,其通过运输活性生物分子(如蛋白质、氨基酸、代谢物和核酸,包括长链非编码RNA(lncRNAs))发挥重要的细胞间通讯作用。这些货物可以有效地递送至靶细胞并诱导高度可变的反应。lncRNAs是由至少200个核苷酸组成的功能性RNA,不编码蛋白质。如今,已知lncRNAs和环状RNAs(circRNAs)在许多生物学过程中发挥关键作用,包括包括癌症在内的多种疾病。越来越多的证据表明,lncRNAs和circRNAs在EVs中活跃存在,产生下游反应,最终通过包括血管生成在内的多种机制影响癌症进展。此外,许多研究表明,一些肿瘤细胞通过分泌EVs促进血管生成,内皮细胞可以摄取这些EVs以诱导新血管形成。在本综述中,我们旨在总结以lncRNAs和circRNAs为货物的EVs的生物活性作用及其对癌症血管生成的影响。此外,我们还将根据目前对circRNAs和lncRNA-EVs的了解讨论未来癌症治疗的临床策略。
