To assess the role KLF12 might have in a clinical setting, a publicly available microarray database that is correlated with lung cancer patient survival was analysed using a cutoff of 37 tumour samples based on KLF12 expression levels.30 Patients with higher KLF12 mRNA levels had increased overall survival relative to those with lower KLF12 levels (Figure 6c). This evidence concerns the gene KLF12 and neoplasm.
