Oxygen availability and metabolic adaptations.

ABSTRACT: Oxygen availability, along with the abundance of nutrients (such as glucose, glutamine, lipids and albumin), fluctuates significantly during tumour evolution and the recruitment of blood vessels, leukocytes and reactive fibroblasts to complex tumour microenvironments. As such, hypoxia and concomitant nutrient scarcity affect large gene expression programmes, signalling pathways, diverse metabolic reactions and various stress responses. This Review summarizes our current understanding of how these adaptations are integrated in hypoxic tumour cells and their role in disease progression.
