Recent studies suggest that hypoxia can promote the formation of specific biomolecular conden-sates, membraneless compartments generated through liquid\u2013liquid phase separation in which regulatory proteins and RNAs become locally enriched at genomic regions, while chromatin mainly serves as an organizational scaffold. Transcription factors, the coacti-vators p300\/CBP, Mediator, and BRD4, chromatin-modifying enzymes, and architectural RNAs such as NEAT1 and MALAT1 partition into these compartments, and their con-densation can help reorganize local chromatin structure and enhancer\u2013promoter interac-tions. Because molecular oxygen is a shared co-substrate for the Jumonji-C histone demethylases and the ten-eleven translocation (TET) DNA dioxygenases, hypoxia reshapes histone methylation and DNA methylation in parallel, and readers that bridge these marks, including UHRF1, may participate in condensate-associated chromatin regulation. Hypoxia-driven condensation of ZHX2 rewires enhancer\u2013promoter contacts and higher-order genome architecture, influencing cell identity, stemness, and metastatic potential, and Polycomb condensates represent another candidate epigenetic compartment that may be influenced by hypoxic signaling. These processes may be particularly important in cancer, where chronic hypoxia provides a sustained stimulus for condensate formation and epigenetic remodeling. Together, these findings support a model in which phase separation and epigenetic reprogramming are not separate layers but one integrated response to low oxygen, offering opportunities to target maladaptive condensates in disease.<\/jats:p>","DOI":"10.3390\/ijms27177926","type":"journal-article","created":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T12:12:25Z","timestamp":1788783145000},"page":"7926","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Biomolecular Condensates Integrate Transcriptional and Epigenetic Responses to Hypoxia"],"prefix":"10.3390","volume":"27","author":[{"given":"Chinmaya Kumar","family":"Patel","sequence":"first","affiliation":[{"name":"Department of Biological Sciences, The University of North Carolina at Charlotte, Charlotte, NC 28223, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8563-7152","authenticated-orcid":false,"given":"Ahmed","family":"Saif","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, The University of North Carolina at Charlotte, Charlotte, NC 28223, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3931-7625","authenticated-orcid":false,"given":"Xiaojun","family":"Ren","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, The University of North Carolina at Charlotte, Charlotte, NC 28223, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Wei, Y., Giunta, S., and Xia, S.
