The A3 adenosine receptor is a G protein-coupled receptor linked to classical second messenger pathways such as those for cAMP production and phospholipase C. In addition, the receptor couples to mitogen-activated protein kinases (MAPK) and to the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) pathway which could give it a role in cell growth, survival, death and differentiation. Interestingly, the A3 receptor has recently been linked to the hypoxia-inducible factor 1 (HIF-1), the main transcription factor regulating the cellular responses to hypoxia. The focus of this chapter centres on downstream mediators of A3 adenosine receptor signaling.

Abstract

The A3 adenosine receptor is a G protein-coupled receptor linked to classical second messenger pathways such as those for cAMP production and phospholipase C. In addition, the receptor couples to mitogen-activated protein kinases (MAPK) and to the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) pathway which could give it a role in cell growth, survival, death and differentiation. Interestingly, the A3 receptor has recently been linked to the hypoxia-inducible factor 1 (HIF-1), the main transcription factor regulating the cellular responses to hypoxia. The focus of this chapter centres on downstream mediators of A3 adenosine receptor signaling.
