KLF7 was up‐regulated in squamous carcinoma samples. (A) Volcano plot shows the overall differential expression landscape in squamous carcinoma samples (n = 43) compared with matched surgical margin (n = 43) from TCGA. KLF7 and genes with |log₂FC| > 6 and P _adj < 0.05 were specified by their symbols. (B) Heatmap illustrates expression values of KLF7 and genes with |log₂FC| > 6 and P _adj < 0.05 in surgical margin and matched squamous carcinoma tissues from TCGA. Blue and red barcodes at the top of the heatmap represent normal and squamous carcinoma samples, respectively. (C) Boxplot shows distribution of KLF7 expression values across surgical margin and matched squamous carcinoma tissues from TCGA. Adj, adjacent; NS, not significant; Tur, tumor.
