Santa Cruz Biotechnology a2b adenosine receptor
Figure 1. Signaling schematic depicting our hypothesis of how adenosine regulates human coronary artery smooth muscle cell cell-cycle progression. Extracellular mitogens activate classical signal transduction pathways that ultimately phosphorylate (and thus activate) ERK1/2 and Akt. ERK1/2 is well known to increase expression of cyclin D (G1 phase cyclin). Phosphorylated Akt activates a signal transduction pathway that stabilizes S-phase kinase–associated protein-2 (Skp2), which is the F-box protein of SCFSkp2 ubiquitin ligase that polyubiquitinates p27Kip1 and thus accelerates the degradation of p27Kip1. Removal of p27Kip1 deinhibits cyclin D activity. Cyclin D activates cyclin-dependent kinases 4 and 6 to hyper-phosphorylate retinoblastoma protein (Rb), thus releasing the transcription factor elongation 2 factor (E2F) and allowing increased expression of G1/S and S phase cyclins. G1/S and S phase cyclins then drive the cell cycle forward to complete mitogenesis and cytokinesis (cell proliferation). Adenosine stimulates <t>A2B</t> receptors that are positively coupled to adenylyl cyclase, which increases the formation cAMP and activates protein kinase A. Protein kinase A decreases expression of Skp2 and inhibits phosphorylation of Akt, resulting in increased levels of p27Kip1 which reduce cyclin D activity. Protein kinase A also inhibits phosphorylation of ERK1/2, which reduces cyclin D expression. This protein kinase A (PKA)–induced signaling converges at cyclin D. This results in inhibition of Rb hyperphosphorylation, and hypophosphorylated Rb can now bind E2F and prevent this transcription factor from increasing the expression of G1/S and S phase cyclins.

Figure 1. Signaling schematic depicting our hypothesis of how adenosine regulates human coronary artery smooth muscle cell cell-cycle progression. Extracellular mitogens activate classical signal transduction pathways that ultimately phosphorylate (and thus activate) ERK1/2 and Akt. ERK1/2 is well known to increase expression of cyclin D (G1 phase cyclin). Phosphorylated Akt activates a signal transduction pathway that stabilizes S-phase kinase–associated protein-2 (Skp2), which is the F-box protein of SCFSkp2 ubiquitin ligase that polyubiquitinates p27Kip1 and thus accelerates the degradation of p27Kip1. Removal of p27Kip1 deinhibits cyclin D activity. Cyclin D activates cyclin-dependent kinases 4 and 6 to hyper-phosphorylate retinoblastoma protein (Rb), thus releasing the transcription factor elongation 2 factor (E2F) and allowing increased expression of G1/S and S phase cyclins. G1/S and S phase cyclins then drive the cell cycle forward to complete mitogenesis and cytokinesis (cell proliferation). Adenosine stimulates A2B receptors that are positively coupled to adenylyl cyclase, which increases the formation cAMP and activates protein kinase A. Protein kinase A decreases expression of Skp2 and inhibits phosphorylation of Akt, resulting in increased levels of p27Kip1 which reduce cyclin D activity. Protein kinase A also inhibits phosphorylation of ERK1/2, which reduces cyclin D expression. This protein kinase A (PKA)–induced signaling converges at cyclin D. This results in inhibition of Rb hyperphosphorylation, and hypophosphorylated Rb can now bind E2F and prevent this transcription factor from increasing the expression of G1/S and S phase cyclins.

B, The effects of 100 nmol/L of 2-chloroadenosine (Cl-Ad) and adenosine (Ad) on cell number in the presence and absence of MRS1754 (MRS; selective A2B antagonist, 100 nmol/L) or inhibitory effects of adenosine in presence or absence of erythro-9-(2-hydroxy-3-nonyl)adenine (EHNA; 1 μmol/L) plus 5-iodotubercidin (IDO; 0.1 μmol/L) and with or without MRS1754 (100nmol/L). C, The effects of adenosine on p27Kip1 and S-phase kinase–associated protein-2 (Skp2) expression in HCASMCs treated with or without adenosine (Ad; 100 nmol/L) for 48 hours. *P<0.05 vs no treatment; §P<0.05 significant reversal of inhibitory effects; #P<0.05 significant increase of inhibitory effects. Values represent mean±SEM from 3 separate experiments using separate HCASMCs, each conducted in triplicate. The optical density (OD) ratio in the bar graphs represents Skp2 or p27Kip1 to β-actin ratio.
