This study targeted to explore circUQCRC2's role and mechanism in childhood asthma. A mouse model of ovalbumin‐induced asthma was established to evaluate the effects of circUQCRC2 on childhood asthma in terms of oxidative stress, inflammation, and collagen deposition. The effects of circUQCRC2 on platelet‐derived growth factor‐BB (PDGF‐BB)‐induced smooth muscle cells (SMCs) were evaluated, the downstream mRNA of miRNA and its associated pathways were predicted and validated, and their effects on asthmatic mice were evaluated. circUQCRC2 levels were upregulated in bronchoalveolar lavage fluid of asthmatic mice and PDGF‐BB‐treated SMCs. Depleting circUQCRC2 alleviated tissue damage in asthmatic mice, improved inflammatory levels and oxidative stress in asthmatic mice and PDGF‐BB‐treated SMC, inhibited malignant proliferation and migration of SMCs, and improved airway remodeling. Mechanistically, circUQCRC2 regulated VEGFA expression through miR‐381‐3p and activated the NF‐κB cascade. circUQCRC2 knockdown inactivated the NF‐κB cascade by modulating the miR‐381‐3p/VEGFA axis. Promoting circUQCRC2 stimulates asthma development by activating the miR‐381‐3p/VEGFA/NF‐κB cascade. Therefore, knocking down circUQCRC2 or overexpressing miR‐381‐3p offers a new approach to treating childhood asthma. [ABSTRACT FROM AUTHOR] |
