Many of the features of the adaptation to hypoxia are mastered by hypoxia inducible factor 1α (HIF1α) that prompts glycolysis, increases the efficiency of mitochondrial O<sub>2</sub> consumption and autophagy to sustain biosynthesis. Mitochondria appear to be at the center of the changes orchestrated by HIF1α, but whether their morphology and ultrastructure change in response to HIF1α activation is unclear.</br></br>Here we will present our data on the occurrence and the role of mitochondrial remodelling in hypoxia. Our results indicate that remodelling of mitochondrial morphology and unltrastructure participate in the hypoxic adaptation.phology and unltrastructure participate in the hypoxic adaptation.)
