Snail family transcriptional repressor 1 radiosensitizes esophageal cancer via epithelial-mesenchymal transition signaling: From bioinformatics to integrated study

Figure 1 Snail family transcriptional repressor 1 is highly expressed in esophageal cancer and significantly correlates with tumor clinical stage and tumor-node-metastasis stage. A: Expression of Snail family transcriptional repressor 1 (SNAI1) in various tumors and adjacent tissues; B: Expression of SNAI1 in paired and unpaired esophageal cancer samples compared with that in adjacent tissues; C: Detection of SNAI1 expression in normal esophageal epithelial cells, TE-1, TE-10 and KYSE-30 cells by Western blot and SNAI1 expression in clinical esophageal cancer patient samples compared with that in adjacent tissues by immunohistochemistry; D: Expression of SNAI1 in different tumor-node-metastasis stages and pathological grades. Kruskal-Wallis test was performed. The error bars represent the SD. ^aP < 0.05; ^bP < 0.01; and ^cP < 0.001.
