Objective To determine the expression of lysine-specific demethylase 1 (LSD1) in esophageal squamous cell carcinoma (ESCC) and normal esophageal tissues
and study the relationship of LSD1 with clinical features
esophageal cancer cell proliferation and apoptosis. Methods The expression of LSD1 and proliferation related antigen (Ki67) in 86 ESCC tissue samples and 29 normal esophageal tissue samples were detected by immunohistochemical assay. TUNEL was used to detect the apoptosis of esophageal cancer cells. The relationship of LSD1 expression with clinical data was analyzed. Results The expression of LSD1 was significantly higher in ESCC than t
hat in normal tissue (89.5% vs 51.7%
P
0.05). It was related to lymph node metastasis and tumor mass growth (
P
0.05)
but not to tumor cell apoptosis. The expression of LSD1 was correlated with the prognosis of the patients (P0.05). Conclusion The high expression of LSD1 in ESCC is correlated with the prognosis of the patients
and may be regarded as a therapeutic target for ESCC.
