Brief description of the research:

Our scientific group is focused on the biological responses executed by the hypoxia-inducible transcription factors (HIFs) to oxygen fluctuations (hypoxia) in different pathological scenarios of enormous biomedical relevance such as solid tumours progression as well as in the adipose tissue expansion (obesity), respiratory pathology and cardiac and peripheral ischemia. A central biological function of HIF factors is to accommodate cellular metabolism to oxygen supply and several studies of the group have explored the role of this HIF-dependent metabolic rewiring in pathophysiology. In this line, our group is particularly interested in the role of HIF signalling in central metabolic players where we identified the role of HIF2-mTORC1 proliferative pathway in cancer progression and lung biology (Elorza et al., 2012 Molecular Cell, Torres-Capelli et al., 2016 Scientific Reports) as well as the role of HIF1a-dependent mitochondrial reprogramming in obesity (Soro et al., 2016 Cell Reports). Our current research continues in this research line about the role of novel HIF-dependent metabolic pathways in cancer biology but also in other pathological settings characterized by hypoxia such as lung disease and tissue ischemia.
