Along with the cartilage malfunction, imbalanced oxygen uptake occurs, changing chondrocytes into type I collagen- and type X collagen-producing dedifferentiated cells, contributing to OA progression. However, mounting evidence suggests treating OA by inducing a hypoxic environment in the articular cartilage, targeting the inhibition of several OA-related pathways to bring chondrocytes into a normal state. This review discusses the implications of OA-diseased articular cartilage on chondrocyte phenotypes and turnover and debates the hypoxic mechanism of action. Furthermore, this review highlights the new understanding of OA, provided by tissue engineering and a regenerative medicine experimental design, modeling the disease into diverse 2D and 3D structures and investigating hypoxia and hypoxia-inducing biomolecules and potential cell therapies. This review also reports the mechanism of hypoxic regulation and highlights the importance of activating and stabilizing the hypoxia-inducible factor and related molecules to protect chondrocytes from mitochondrial dysfunction and apoptosis occurring under the influence of OA.<\/jats:p>","DOI":"10.3390\/ijms23105356","type":"journal-article","created":{"date-parts":[[2022,5,11]],"date-time":"2022-05-11T10:19:46Z","timestamp":1652264386000},"page":"5356","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Remodeling Osteoarthritic Articular Cartilage under Hypoxic Conditions"],"prefix":"10.3390","volume":"23","author":[{"given":"Mohd Heikal","family":"Mohd Yunus","sequence":"first","affiliation":[{"name":"Department of Physiology, Universiti Kebangsaan Malaysia, Cheras, Kuala Lumpur 56000, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yemin","family":"Lee","sequence":"additional","affiliation":[{"name":"MedCentral Consulting, Jalan 27\/117A, Bandar Tun Razak, Cheras, Kuala Lumpur 56000, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9717-6691","authenticated-orcid":false,"given":"Abid","family":"Nordin","sequence":"additional","affiliation":[{"name":"MedCentral Consulting, Jalan 27\/117A, Bandar Tun Razak, Cheras, Kuala Lumpur 56000, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kien Hui","family":"Chua","sequence":"additional","affiliation":[{"name":"Department of Physiology, Universiti Kebangsaan Malaysia, Cheras, Kuala Lumpur 56000, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruszymah","family":"Bt Hj Idrus","sequence":"additional","affiliation":[{"name":"Department of Physiology, Universiti Kebangsaan Malaysia, Cheras, Kuala Lumpur 56000, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,11]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2022, February 16).
