Journal of Translational Internal Medicine, Journal Year: 2023, Volume and Issue: 11(4), P. 372 - 381

Published: Dec. 1, 2023

Circular RNAs (circRNAs) are a class of single-stranded with covalently closed structures. Owing to their not having 3' or 5' ends, circRNAs highly durable and insusceptible exonuclease-mediated degradation. Moreover, some certain structures translatable, making them novel vaccines. Vaccines efficient tools for immunotherapy, such as the prevention infectious diseases cancer treatment. The immune system is activated during immunotherapy fight against abnormal allies invaders. CircRNA vaccines represent potential new avenue in vaccine era. Recently, several circRNA have been synthesized tested vitro vivo. Our review briefly introduces current understanding biology function translatable circRNAs, molecular biology, synthetic methods, delivery circRNA, We also discussed challenges future directions field by summarizing developments past few years.

Functions of Circular RNA in Human Diseases and Illnesses

Non-Coding RNA, Journal Year: 2023, Volume and Issue: 9(4), P. 38 - 38

Published: July 4, 2023

Circular RNAs (circRNAs) represent single-stranded RNA species that contain covalently closed 3′ and 5′ ends provide them more stability than linear RNA, which has free ends. Emerging evidence indicates circRNAs perform essential functions in many DNA viruses, including coronaviruses, Epstein–Barr cytomegalovirus, Kaposi sarcoma viruses. Recent studies have confirmed are present play various important such as evading host immune response, disease pathogenesis, protein translation, miRNA sponges, regulating cell proliferation, virus replication. Studies can be biological signatures or pathological markers for autoimmune diseases, neurological cancers. However, our understanding of viruses is still limited, functional evaluation viral to completely understand their functions. In the review, we describe metabolism cellular roles circRNA, its diseases circRNA found interact with proteins, DNA, thus modulate processes, transcription, splicing, other interfere signaling pathways take part vital biological, physiological, cellular, pathophysiological processes. We also summarize recent demonstrating circRNA’s this growing field research.

CircRNAs in tumor immunity and immunotherapy: Perspectives from innate and adaptive immunity

Cancer Letters, Journal Year: 2023, Volume and Issue: 564, P. 216219 - 216219

Published: May 3, 2023

Tumor immunotherapy is a new therapeutic approach that has been evolving in the last decade and dramatically changed treatment options for cancer. Circular RNAs (circRNAs) are non-coding (ncRNAs) with high stability, tissue-specific cell-specific expression. There growing evidence circRNAs involved regulation of both adaptive innate immunity. They play important roles tumor by affecting macrophage, NK T cell function. The stability tissue specificity make them ideal candidate biomarkers effects. CircRNAs also represent one promising targets or adjuvant immunotherapy. Investigations this field progress rapidly provide essential support diagnosis, prognosis guidance cancers future.

The potential application of encapsulated exosomes: A new approach to increase exosomes therapeutic efficacy

Biomedicine & Pharmacotherapy, Journal Year: 2023, Volume and Issue: 162, P. 114615 - 114615

Published: April 1, 2023

Cell therapy is one of the methods that have shown promising results in treating diseases recent decades. However, use different types cells comes with limitations. The application immune cell can lead to cytokine storms and inappropriate responses self-antigens. Also, stem has potential create tumors. may not migrate injury site after intravenous injection. Therefore, using exosomes from as therapeutic candidates were proposed. Due their small size favorable characteristics, such biocompatibility immunocompatibility, easy storage isolation, attracted much attention. They are used many diseases, including cardiovascular orthopedic autoimmune cancer. various studies efficiency (Exo) be increased by loading drugs microRNAs inside them (encapsulated exosomes). analyzing investigating encapsulated exosomes' ability critical. In this study, we examined related cancer infectious regenerative medicine. Compared intact exosomes, show a higher ability. Therefore it suggested method depending on treatment type increase treatment's efficiency.

Breast cancer (BC) is one of the most frequent cancer-related deaths in women worldwide. Studies have shown potential impact circRNAs multiple human tumorigeneses. Research on vital signaling pathways and therapeutic targets indispensable. Here, we aimed to investigate clinical implications underlying mechanisms circ_0042881 BC. RT-qPCR validated was notably elevated BC tissues plasma, closely associated with clinicopathological features. Functionally, significantly accelerated proliferation, migration, invasion cells vitro tumor growth metastasis vivo. Mechanistically, promoted progression by sponging miR-217 relieve its inhibition effect son sevenless 1 (SOS1), which further activated RAS protein initiated downstream cascades, including MEK/ERK pathway PI3K/AKT pathway. We also demonstrated that treatment BAY-293, an inhibitor SOS1 interaction, attenuated induced overexpression. Furthermore, Eukaryotic initiation factor 4A-III (EIF4A3) could facilitate circularization. Altogether, proposed a novel network circ_0042881, EIF4A3, influences process tumorigenesis miR-217/SOS1 axis.
