Abstract
Laryngeal cancer remains a significant global health concern, with poor prognosis for advanced-stage disease highlighting the need for novel diagnostic, prognostic, and therapeutic approaches. Circular RNAs (circRNAs), a class of covalently closed non-coding RNAs, have emerged as important regulators of gene expression and cellular processes in various cancers, including laryngeal cancer. This review summarizes the current understanding of circRNAs in laryngeal cancer, covering their biogenesis, regulatory mechanisms, and potential clinical applications. We explore the diverse functions of circRNAs, including their roles as miRNA sponges, protein interactors, and direct mRNA regulators, and their influence on key cellular processes such as proliferation, invasion, and metastasis. The review highlights promising circRNAs as diagnostic and prognostic biomarkers, as well as potential therapeutic targets. We also outline current strategies for circRNA modulation, including suppression techniques like RNA interference and CRISPR/Cas systems, and overexpression methods using vectors and synthetic circRNAs.

Guo Z, Zhao Y, Guo N, Xu M, Wang X. Hsa_circYARS interacts with miR-29a-3p to up-regulate IREB2 and promote laryngeal squamous cell carcinoma progression. Discov Oncol 2024; 15:401. [PMID: 39225900 PMCID: PMC11371998 DOI: 10.1007/s12672-024-01198-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Accepted: 07/26/2024] [Indexed: 09/04/2024] Open
Abstract
OBJECTIVE This study was to investigate the carcinogenic capacity of circYARS in laryngeal squamous cell carcinoma (LSCC) and to reveal its potential mechanism as a competitive endogenous RNA. METHODS The differentially expressed circRNA and mRNA in LSCC were detected by RT-qPCR. Dual luciferase reporter assay and RIP were conducted to test the interaction between circYARS, miR-29a-3p, and IREB2. The functional effects of these molecules were investigated by CCK-8, flow cytometry, colony formation assay, Transwell, Western blot, and xenotransplantation mouse models. RESULTS In LSCC tissues and cell lines, circYARS and IREB2 levels were enhanced, while miR-29a-3p level was lowered. Depleting circYARS led to decreased IREB2 by promoting miR-29a-3p expression. As a result of miR-29a-3p enhancement or circYARS silence, the proliferative, migratory, and invasion of cancer cells were suppressed and apoptosis was stimulated. CONCLUSION circYARS is involved in the tumorigenicity and progression of LSCC through the miR-29a-3p/IREB2 axis, providing strategies and targets for therapeutic intervention of LSCC.
