The cause of synovitis in rheumatoid arthritis involves the interaction between immune cells/macrophages and fibroblast-like synoviocytes (FLSs-RA). The impact of circular RNAs on FLSs and their role in RA pathology is still unknown. This study aimed to investigate the roles and molecular mechanisms of circular RNA FNDC3B in regulating cell injury and glucose metabolism of FLSs in RA. We demonstrated that circFNDC3B was significantly upregulated and miR-125a-5p was significantly downregulated in FLSs from RA patients. When circFNDC3B was silenced or miR-125a-5p was overexpressed, it reduced FLSs-RA glucose metabolism and increased oxidative stress-induced cell injury. Through bioinformatics analysis, RNA pull-down, and luciferase assays, it was found that circFNDC3B sponged miR-125a-5p to create a ceRNA network in FLSs-RA. The glucose metabolism rate was elevated in FLSs-RA, showing a glucose-dependent characteristic compared to normal FLSs. The enzyme hexokinase 2 (HK2), which is crucial for glucose metabolism, was identified as a direct target of miR-125a-5p in FLSs. In rescue experiments, restoring miR-125a-5p in circFNDC3B-overexpressing FLSs-RA successfully counteracted the circFNDC3B-promoted glucose metabolism and resistance to cell injury. In conclusion, this study highlighted the important roles and molecular mechanisms of circFNDC3B in accelerating glucose metabolism and preventing cell apoptosis in fibroblast-like synoviocytes during rheumatoid arthritis by modulating the miR-125a-5p-HK2 axis. Targeting the circFNDC3B-mediated glucose metabolism pathway could be a promising strategy for rheumatoid arthritis therapy.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10616-025-00745-3.</p>","PeriodicalId":10890,"journal":{"name":"Cytotechnology","volume":"77 3","pages":"83"},"PeriodicalIF":2.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11947371/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143751456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MicroRNAs (miRNAs) are essential non-coding RNAs that exert pivotal regulatory functions in diverse physiological and pathological processes, including tumorigenesis, disease progression, and drug resistance. The association of miR-34a-5p with osteosarcoma has been documented; However, its underlying mechanisms remain poorly understood.This investigation delineates the impact of miR-34a-5p on the proliferation, invasion, migration, and apoptosis of osteosarcoma cells via in vitro assays, aiming to elucidate the associated mechanisms. Employing up-regulation and knockdown strategies, this study evaluated the roles of miR-34a-5p and FoxM1 in modulating osteosarcoma cell behaviors.These effects were further validated through a rescue experiment, providing robust evidence of the miRNA's impact. Quantitative RT-PCR showed that, compared with normal tissues, miR-34a-5p was significantly downregulated while FoxM1 was markedly upregulated in nine osteosarcoma samples.Increased miR-34a-5p expression attenuated proliferation, migration, and invasion in MG-63 and U2OS cell lines, while enhancing apoptosis.Bioinformatic analyses and dual luciferase assays identified FoxM1 as a downstream target of miR-34a-5p, a finding corroborated by quantitative RT-PCR and Western blotting, which confirmed the negative regulation of FoxM1 by miR-34a-5p.Additionally, FoxM1 knockdown reduced tumor cell proliferation, migration, and invasion, concurrently promoting apoptosis; co-inhibition of miR-34a-5p and FoxM1 partially mitigated these effects. This study demonstrates that miR-34a-5p significantly inhibits osteosarcoma cell proliferation, migration, and invasion, while promoting apoptosis, by targeting and suppressing FoxM1. Our findings suggest that miR-34a-5p is a potential tumor suppressor with therapeutic value.

A bladder cancer mouse model was established with control (NC), OE-BAP1, and KD-BAP1 groups to assess the effects of BAP1 overexpression and knockdown. Western blot analysis evaluated the expression levels of BAP1, SP1, YAP, PD-L1, CAS6, AXL, and related signaling proteins.

The influence of the SNHG25/miR-329-3p/PPP2R2D axis on CRC progression was explored through in vitro assays including CCK-8, colony formation, wound healing, Transwell assays and in vivo orthotopic xenografts assay. The interaction between miR-329-3p and SNHG25 or PPP2R2D was examined by RNA pull-down, RIP, and luciferase reporter assays. SNHG25 presented high expression in CRC cell lines. Silencing of SNHG25 suppressed the malignant phenotypes of CRC cells in vitro and tumor growth in vivo. MiR-329-3p, which displayed low expression in CRC cells, was sponged by SNHG25. Downregulation of miR-329-3p reversed the inhibitory effects of SNHG25 silencing on CRC cell malignant behaviors. Additionally, PPP2R2D served as a miR-329-3p downstream target, whose expression was downregulated by overexpressing miR-329-3p. Importantly, overexpression of PPP2R2D rescued SNHG25 silencing-induced repression on CRC cell malignancy.
