Brain microvascular endothelial cells (BMECs) are important structural and functional components of the BBB; however, the molecular changes that occur in BMECs during hypoxia remain unknown. We reported the molecular and functional changes in BMECs under hypoxia through whole-transcriptome sequencing, small RNA microarray, TMT quantitative proteomic, and untargeted metabolomic analyses. We found that hypoxia affected pathways such as ncRNA processing, the HIF-1 signaling pathway, the cell cycle, DNA replication, glucose metabolism, protein synthesis, and inflammation pathways. ncRNA processing was significantly downregulated. However, the levels of some miRNAs, tRNAs, tsRNAs, snoRNAs, lncRNAs, and circRNAs were significantly upregulated under hypoxia. These results suggest that ncRNAs may play an important role in oxidative stress and cellular adaptation to hypoxia, helping us understand the pathological process of BBB injury and providing potential targets for the treatment of BBB-related cerebrovascular diseases.<\/jats:p>","DOI":"10.3390\/ijms26125629","type":"journal-article","created":{"date-parts":[[2025,6,12]],"date-time":"2025-06-12T03:59:17Z","timestamp":1749700757000},"page":"5629","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Multiomics Analysis Reveals Role of ncRNA in Hypoxia of Mouse Brain Microvascular Endothelial Cells"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-1851-6750","authenticated-orcid":false,"given":"Qixin","family":"Shi","sequence":"first","affiliation":[{"name":"Department of Aerospace Physiology, Air Force Medical University, Xi\u2019an 710032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuai","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Aerospace Physiology, Air Force Medical University, Xi\u2019an 710032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaohua","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Aerospace Physiology, Air Force Medical University, Xi\u2019an 710032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Aerospace Physiology, Air Force Medical University, Xi\u2019an 710032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Aerospace Physiology, Air Force Medical University, Xi\u2019an 710032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun-Gang","family":"Bai","sequence":"additional","affiliation":[{"name":"Department of Aerospace Physiology, Air Force Medical University, Xi\u2019an 710032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Man-Jiang","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Aerospace Physiology, Air Force Medical University, Xi\u2019an 710032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Aerospace Physiology, Air Force Medical University, Xi\u2019an 710032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1584","DOI":"10.1038\/nm.3407","article-title":"Development, maintenance and disruption of the blood-brain barrier","volume":"19","author":"Daneman","year":"2013","journal-title":"Nat.
