Recent Insights into the Angioregulatory Role of Long Non-coding RNAs and Circular RNAs in Gliomas: From Signaling Pathways to Clinical Aspects

Abstract

Abstract: The most prevalent and severe malignancy of the central nervous system within the brain is glioma. Glioma is a vascularized cancer, and angiogenesis is necessary for glioma growth, invasion, and recurrence. It is also believed that this factor is this factor to be accountable for therapy resistance in many cancers, including glioma. The process of angiogenesis, which plays a crucial role in both health and disease situations such as cancer, involves the creation of new blood vessels from pre-existing ones. Non-coding RNAs (ncRNAs) are unique molecules that have been found to possess a wide range of abilities to modify the expression of various genes. They carry out their gene-modulating roles at a variety of distinct levels, including post-transcriptional and post-translational levels. Long ncRNAs (lncRNAs) and circular RNAs (circRNAs) are a group of ncRNA that have attracted particular attention and are involved in the angiogenesis mechanism in cancer. Understanding the regulatory mechanisms of these RNAs in the angiogenesis process in gliomas provides unique fundamental information about the process of tumor-associated neovascularization. On the other hand, due to developments in the characterisation of lncRNAs and circRNAs, these novel structures may potentially be used in clinics as possible biomarkers for treatment strategies that target tumor angiogenesis. Throughout the review, new knowledge and views about the angioregulatory function of circRNAs and lncRNAs in gliomas have been presented. Additionally, we talk about the novel idea of ncRNA-based therapeutics for gliomas in the future.
