KLF8 and neoplasm: We initially analyzed the expression of miR-24-3p and KLF8 in 18 pairs of tumor tissues and nontumor tissues of LUAD by qRT–PCR and found that the expression levels of miR-24-3p declined in LUAD tissues than those in adjacent nontumor tissues (Figure 1(a)), while KLF8 mRNA expression was increased in LUAD tissues than that in adjacent nontumor tissues (Figure 1(b)).
