Fig. (5). mGluRI uses Akt1 activation to protect against phosphorylation of β-catenin during NO exposure.

Neuronal protein extracts (50 μg/lane) were immunoblotted with anti-phosphorylated-β-catenin (p-β-catenin) at 6 hours following NO (NOC-9 (shown) or SNP, 300 μM) exposure. Transfection with Akt1 siRNA significantly reduced expression of p-β-catenin during DHPG (750 μM) alone or during NO exposure. Band density was performed using the public domain NIH Image program (developed at the U.S. National Institutes of Health and available at http://rsb.info.nih.gov/nih-image/) (*P<0.01 vs. NO).
