Hypoxia may facilitate metastasis and tumor advancement in solid tumors. Intratumoral hypoxia may facilitate tumor aggressiveness by stabilizing hypoxia-inducible factor-1α (HIF-1α). Various transcriptional and epigenetic pathways modulate hypoxia-stimulated gene expression and tumor progression. Noncoding RNAs longer than 200 nt are long noncoding RNAs (lncRNAs). Current lncRNA profiling in several human tumor types revealed that lncRNA expression and deregulation vary by tumor type and may undergo transcriptional, genomic, and epigenetic modifications. LncRNAs controlled by hypoxia have emerged as a prominent focus in hypoxia-regulated biology due to their ability to influence multiple biological procedures associated with tumorigenesis. Hypoxia-regulated lncRNAs may influence tumor development, growth, anti-apoptosis, migration, invasion, angiogenesis, and tumor metabolism. In this light, hypoxia-inducible lncRNAs could interact with protein/protein complex and chromatin/epigenetic factors and another mechanism, thus favoring tumorigenesis. Conversely, lncRNAs may control hypoxia signaling by stabilizing HIF-1α via several mechanisms. Nonetheless, several undiscovered lncRNAs remain that may mediate or regulate the hypoxia axis. Consequently, the novel lncRNAs modulated by hypoxia or that influence hypoxia signaling have yet to be discovered and thoroughly described. Herein, we aim to classify suitable lncRNA targets to offer a feasible therapeutic modality for hypoxia-driven cancers.
缺氧可能促进实体瘤的转移和肿瘤进展。肿瘤内缺氧可能通过稳定缺氧诱导因子-1α(HIF-1α)来促进肿瘤侵袭性。各种转录和表观遗传途径调节缺氧刺激的基因表达和肿瘤进展。长度超过200 nt的非编码RNA为长链非编码RNA(lncRNA)。目前对几种人类肿瘤类型的lncRNA分析表明,lncRNA的表达和失调因肿瘤类型而异,并且可能经历转录、基因组和表观遗传修饰。由于缺氧调控的lncRNA能够影响与肿瘤发生相关的多个生物学过程,因此它们已成为缺氧调控生物学的一个突出研究重点。缺氧调控的lncRNA可能影响肿瘤的发生、生长、抗凋亡、迁移、侵袭、血管生成和肿瘤代谢。有鉴于此,缺氧诱导的lncRNA可能通过与蛋白质/蛋白质复合物以及染色质/表观遗传因子相互作用和其他机制,从而促进肿瘤发生。相反,lncRNA可能通过多种机制稳定HIF-1α来控制缺氧信号传导。尽管如此,仍有一些未被发现的lncRNA可能介导或调节缺氧轴。因此,由缺氧调节或影响缺氧信号传导的新型lncRNA尚未被发现和充分描述。在此,我们旨在对合适的lncRNA靶点进行分类,为缺氧驱动的癌症提供一种可行的治疗方式。
