Protein kinase C regulates mRNAs encoding several G protein-linked receptors but its role in adenosine A2a receptor expression is not known. We tested the hypothesis that protein kinase C activated by tetradecanoyl phorbol acetate (TPA) regulates adenosine A2a receptor mRNA levels. SH-SY5Y human neuroblastoma cells express adenosine receptors which positively couple to adenylyl cyclase with a pharmacologic profile expected of the A2a subtype. Northern blotting demonstrated an adenosine A2a receptor mRNA species of similar molecular size in SH-SY5Y cells and in human brain. TPA increased adenosine A2a receptor mRNA in a dose- and time-dependent fashion. Transcription or translation inhibition prevented increases in adenosine A2a receptor mRNA. Bisindolylmaleimide blocked TPA effects. Adenosine A2a receptor mRNA stability was unchanged by TPA. This study identifies a human neuroblastoma cell line expressing functional adenosine A2a receptors. Protein kinase C activation appears to enhance transcription of the adenosine A2a receptor gene.
