To verify whether possible associations in the expressions of TβRII, miR-20a, c-Myc and miR-145 are present in lung cancer, we have used the expression data for TβRII, miR-20a, c-Myc and miR-145 from a total of 488 primary lung adenocarcinoma specimens and 490 primary lung squamous carcinoma specimens as described in “Figure 1C”. This evidence concerns the gene MYC and lung carcinoma.
