Abstract


Adenosine receptors (A1, A2a, A2b and A3) have several physiological and pathological roles in cancer cell lines. The present study was carried out to evaluate the mRNA and protein expression profile and functional role of adenosine receptors in OVCAR-3, Caov-4 and SKOV-3 ovarian cancer cell lines. The levels of mRNA and protein expression of A1, A2a, A2b and A3 adenosine receptors in the ovarian cancer cell lines were measured by Real-time PCR and western blotting. The functional roles of adenosine receptors were investigated through measurement of cAMP levels after agonist treatment. The mRNA and protein of all adenosine receptors subtypes were expressed in the ovarian cancer cell lines. Our findings demonstrated that A2b and A3 had the most mRNA and protein expression. Moreover, cAMP assay confirmed the functional role of A2b and A3 adenosine receptors. This findings demonstrated that A2b and A3 subtypes are most important adenosine receptors in humn ovarian cancer cell lines. This information provide a strong possibility into the relationship of A2b and A3 adenosine receptor and ovarian cancer.
