A2AR activation triggers β-catenin in osteoblast. A) β-Catenin total, active, and pSer522 activation was analyzed 24 h after stimulation with CGS21680 ± ZM241385 by Western blot of osteoblast lysates. B) β-Catenin total, active, and pSer522 activation in cytoplasm and nucleus was analyzed 24 h after stimulation with CGS21680 ± ZM241385. Data are expressed as the means of 4 independent experiments. ***P < 0.001, **P < 0.01; *P > 0.05 vs. nonstimulated control.
