However, the trend was reversed in terms of the overall survival data (Figure 5E,F) in ovarian cancer—GSE26712 (n = 195 tumor specimens) [71] and GSE30161 (n = 58 cancer samples) [72] and lung cancer (Figure 5G,H)—GSE30219 (n = 293 lung tumor samples) [73] and caArray (n = 504 samples) [74], where high KLF4 levels correlated with worse patient outcomes. This evidence concerns the gene KLF4 and cancer.
