KLF4 and non-small cell lung carcinoma: 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.
