[PMID: 33996542 PMCID: PMC8117014 DOI: 10.3389/fonc.2021.616202] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Accepted: 04/07/2021] [Indexed: 12/13/2022] Open
Abstract
Circular RNAs (circRNAs) are a novel type of non-coding RNAs. Because of their characteristics of a closed loop structure, disease- and tissue-specificity, and high conservation and stability, circRNAs have the potential to be biomarkers for disease diagnosis. Head and neck cancers are one of the most common malignant tumors with high incidence rates globally. Affected patients are often diagnosed at the advanced stage with poor prognosis, owing to the concealment of anatomic sites. The characteristics, functions, and specific mechanisms of circRNAs in head and neck cancers are increasingly being discovered, and they have important clinical significance for the early diagnosis, treatment, and prognosis evaluation of patients with cancer. In this study, the generation, characteristics, and functions of circRNAs, along with their regulatory mechanisms in head and neck cancers have been summarized. We report that circRNAs interact with molecules such as transcription and growth factors to influence specific pathways involved in tumorigenesis. We conclude that circRNAs have an important role to play in the proliferation, invasion, metastasis, energy and substance metabolism, and treatment resistance in cancers.

[PMID: 33041662 PMCID: PMC7539413 DOI: 10.1186/s12935-020-01557-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Accepted: 09/14/2020] [Indexed: 12/16/2022] Open
Abstract
Background Circular RNAs (circRNAs) are important regulators in the pathogenesis of diseases and affects the occurrence and development of diseases. However, the role of circRNAs in osteosarcoma (OS) has not been fully elucidated. Methods The expression of circ_0000285, miR-409-3p and insulin-like growth factor binding protein 3 (IGFBP3) was detected using quantitative real-time PCR (qRT-PCR). The protein level of IGFBP3 was measured using western blot. CCK-8 and colony formation assays were used to determine cell proliferation. Flow cytometry was applied to measure cell cycle and cell apoptosis. Transwell assay was used to assess cell invasion and migration. Dual-luciferase reporter assay and RNA Binding Protein Immunoprecipitation (RIP) assay were performed to determine the relationship among circ_0000285, miR-409-3p and IGFBP3. The animal experiments were performed to determine the function of circ_0000285 in vivo. Results In this study, we found that the expression of circ_0000285 was significantly increased in OS tissues and cells and was enriched in the cytoplasm. Knockdown of circ_0000285 inhibited OS growth in vitro and in vivo. Moreover, miR-409-3p was a target miRNA of circ_0000285 and miR-409-3p targets to IGFBP3 in OS. Besides, circ_0000285 could promote proliferation, migration, invasion and inhibit apoptosis of osteosarcoma by miR-409-3p/IGFBP3 axis. Conclusion In this study, circ_0000285 regulated proliferation, migration, invasion and apoptosis of OS cells by miR-409-3p/IGFBP3 axis, implying that circ_0000285 was a potential target for OS therapy.

[PMID: 32982457 PMCID: PMC7509321 DOI: 10.2147/cmar.s253174] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Accepted: 07/16/2020] [Indexed: 01/08/2023] Open
Abstract
Background Circular RNAs (circRNAs) are involved in the development of human cancers, including cervical cancer (CC). However, the role and mechanism of the circRNA hsa_circ_0000285 (circ_0000285) in CC development remain largely unknown. Methods Thirty paired CC and adjacent normal tissue samples were harvested. CC cell lines SiHa and HeLa were cultured in this study. The expression of circ_0000285, miR197-3p and ELK1 was detected via qRT-PCR or Western blot. CC development was assessed via cell viability, colony formation, apoptosis, cell cycle, and autophagy using MTT, colony-formation assays, flow cytometry and Western blot. The target association was analyzed via dual luciferase–reporter assay, RNA immunoprecipitation, and RNA pull-down. The role of circ_0000285 in CC in vivo was analyzed using a xenograft model. Results circ_0000285 abundance was enhanced in CC tissue and cells and mainly located in cytoplasm. Silence of circ_0000285 suppressed cell viability and colony formation, arrested the cell cycle at the G0/G1 phase, and induced apoptosis and autophagy in CC cells. miR197-3p was targeted by circ_0000285, and miR197-3p knockdown reversed the effect of circ_0000285 silence on CC development. miR197-3p directly targeted ELK1 to inhibit CC development. circ_0000285 regulated ELK1 by modulating miR197-3p. Knockdown of circ_0000285 reduced xenograft tumor growth in vivo. Conclusion Knockdown of circ_0000285 repressed CC development by increasing miR197-3p and decreasing ELK1.
