  • the A 3 adenosine receptor a G i protein-associated cell surface receptor
  • the receptor is highly expressed in various tumor cell types while expression in adjacent normal tissues is relatively low.
  • Activation of the receptor by a specific synthetic agonist induces modulation of downstream signal transduction pathways which include the Wnt and the NF- ⁇ B, resulting in tumor growth inhibition (1-5).
  • a 3 AR agonists inhibit the development of colon, prostate and pancreatic carcinomas as well as melanoma and hepatoma.
  • a 3 AR agonists were also been shown to act as anti-inflammatory agents by ameliorating the inflammatory process in different experimental autoimmune models such as rheumatoid arthritis, Crohn's disease and multiple sclerosis (6-10). It was proposed also that the A 2A and A 3 receptors mediate the anti-inflammatory effects of methotrexate (11).
  • a 3 adenosine receptor (A 3 AR) expression levels are elevated in cancer cells as compared to normal cells (12). Thus, the A 3 AR expression level has been described as a means for the diagnosis of cancer (13). In addition, A 3 AR expression levels have also been described to be elevated in peripheral blood cells of patients with colorectal cancer (14).

Furthermore, it was found that in subjects who respond to anti-inflammatory drug treatment, there is a reduction in the level of A 3 adenosine receptor expression in their WBC. This finding paves the way for the use of the A 3 adenosine receptor expression level as a means for the diagnosis of an inflammatory state, as well as other applications described below.
