ESM1 Is a Promising Therapeutic Target and Prognostic Indicator for Esophageal Carcinogenesis/Esophageal Squamous Cell Carcinoma
Figure 6
ESM1 was highly expressed in esophageal carcinoma and the corresponding survival rate. (a) The mRNA expression of ESM1 was detected by qRT–PCR in adjacent normal tissue and esophageal cancer. (b) ESM1 protein expression was detected by IF of adjacent normal tissue and esophageal cancer tissue. Scale bar equals 50 μm. Blue indicates cell nuclei, and green indicates ESM1. The mean fluorescence intensity in adjacent normal tissue and esophageal cancer was and , respectively. (c) Normal squamous epithelium adjacent to carcinoma (HE×100). (d) Esophageal squamous cell carcinoma (HE×200). (e) Negative expression of ESM1 in squamous epithelium adjacent to carcinoma (IHC SP×100). (f–i) ESM1 is (-)(+)(++)(+++) in ESCC (IHC SP×200). (j) Patients whose ESM1 IHC high-expression had a lower 5-year overall survival rate (). and .
