TOMM20 showed a mitochondrial staining pattern, and it was found expressed in carcinoma cells both in LUAD (Figure 1E and Supplementary Table 1) and in LUSC (Figure 1F and Supplementary Figure 1C), whereas absent in normal lung tissue (Figures 1E, F, Supplementary Table 1 and Supplementary Figure 1C). Here, TOMM20 is linked to carcinoma.
