Among the three disease types, LUAD with adenomas and adenocarcinomas had a higher RNA expression of PSMC6 than the other two disease types (Figure 2(b), Kruskal-Wallis test, p value < 0.001), indicating that LUAD with the disease type of adenomas and adenocarcinomas might have a higher degree of malignancy. The gene discussed is PSMC6; the disease is adenocarcinoma.
