Our results showed that, though it appears no statistically significant difference, an upward trend of KLF4 expression in NSCLC tissues compared with matched normal lung tissues and a trend of KLF4 and Rictor positive correlation were observed (Supplementary Figure 5A and 5B), suggesting that KLF4 expression level was upregulated in our NSCLC cohort. Here, RICTOR is linked to non-small cell lung carcinoma.
