Mcl-1 expression is upregulated in esophageal cancer tissue and is associated with poor patient prognosis. a Samples were categorized into four levels of expression patterns. ten normal esophageal tissues were compared with forty tumor samples from a US Biomax microarray. The brown staining indicates Mcl-1 expression in a representative sample (scale bar = 100 μm). b Kaplan–Meier survival curve for overall survival of patients with low and high expression of Mcl-1 based on mRNA from The Cancer Genome Atlas (TCGA) dataset
