Challenges in mimicking hypoxia: insights into HIF-regulated MiRNA expression induced by DMOG and CoCl2

Anna Barton, Maciej Jaśkiewicz, Anna Więch -Walów et al. · 2025 · Cell Communication and Signaling

Abstract The cellular and tissue response to acute hypoxia is mediated by a complex adaptive response initiated by hypoxia-inducible factors (HIF) 1 and 2. HIF proteins are key transcription factors that modulate gene expression to adapt cells to the low oxygen tension. Cellular studies of hypoxia have used the low oxygen model by using hypoxia chambers to monitor the gene expression changes, while others have utilized hypoxia mimetics in normoxic conditions. Here, we provide a comparison of the utility and limitations of two hypoxia mimetics by studying the changes in the miRNA and mRNA expre
