Using GEPIA to analyze the TCGA database, the mRNA expression between BMI1 and TYMS or SP1 and TYMS displayed a significantly positive correlation among lung adenocarcinoma patients (Figure S1, R = 0.42, p = 0 for BMI1/TYMS; R = 0.35, p = 3.6 × 10−15 for SP1/TYMS). This evidence concerns the gene BMI1 and lung adenocarcinoma.
