Fifty gene sets were upregulated in lung adenocarcinoma, and 10 gene sets, namely, oxidative phosphorylation, the MYC target V2, unfolded protein response, estrogen early response, adiposeness, glycolysis, the MYC target V1, mtorc1 signaling, wnt beta catenin signaling, and E2F targets, were greatly enriched, with normalized P values < 5% among the 50 gene sets (Figs. 1 and 2). Here, MYC is linked to lung adenocarcinoma.
