Expression of phosphorylated (inactive) PP1α proteins increases in stable DARPP-32-overexpressed NSCLC cells upon transient expression of constitutively active IKKα cDNA plasmids compared to GFP- or kinase-dead IKKα- expression plasmids (Fig. 3a, b). The gene discussed is PPP1R1B; the disease is non-small cell lung carcinoma.
