Data obtained from TCGA database (https://portal.gdc.cancer.gov/) were analyzed to explore the correlation between CD151 and integrin α3/α6/β1 mRNA levels in 103 normal tissues and 999 NSCLC tissues (Additional file 7: Fig. S4a-c) and 188 lung cancer cell lines (Additional file 7: Fig. S4d-f). This evidence concerns the gene CD151 and non-small cell lung carcinoma.
