I: HtrA1 protein expression in esophageal cancer and the adjacent normal esophageal tissues and its relationship with clinicopathological factors. II: The relative changes of HtrA1 protein expression in esophageal carcinoma and its adjacent normal esophageal tissues. (A) Adjacent normal esophageal tissue; (B) esophageal cancer tissue; (C) highly and intermediately differentiated; (D) poorly differentiated; (E) early pathological stage (I, II) patients; (F) mid-to-late pathological stage (III, IV) patients; (G) lymph node metastasis negative; (H) lymph node metastasis positive; (I) distant metastasis negative; (J) distant metastasis positive. *p < 0.05.
