To explore the effect of CNVs in MCL1 and BCL2L1 on the corresponding genes expressions, we derived CNV data (in level 3) for tumor tissues from 491 LAUD and 487 LUSC patients in September, 2014., and normalized gene expression data (in level 3) from 1084 LAUD and 1033 LUSC tissues in TCGA database (performed on 17 November 2014). This evidence concerns the gene BCL2L1 and neoplasm.
