Regarding the other two genes (PKN1 and PPP1R9A), although the frequency of aberrant gene expression in the other 10 types of carcinoma was 0–12.0% (PKN1) and 0–12.0% (PPP1R9A), no lung adenocarcinoma tissue sample showed aberrant gene expression (Fig 4(B) and 4(C) and S10 Table). The gene discussed is PKN1; the disease is carcinoma.
