description Background Rad51 is a protein which plays a vital role in DNA double-strand break repair and maintenance of telomeres. However, the underlying mechanism for its action in esophageal squamous cell carcinoma (ESCC) remains unclear. Patients and Methods Eighty-seven patients with ESCC were enrolled in this study. Expression of Rad51 in ESCC was determined by immunohistochemistry and correlated with clinicopathological variables by Chi square test. The role of Rad51 in patient survival was determined by Kaplan–Meier estimates. The effects of Rad51 knockdown and overexpression on esophageal cancer growth, migration, and invasion were examined using TE8, CE81T, and KYSE70 cells. The mechanisms involved were also analyzed. Nude mice models were used for assessment of tumor growth. Results Rad51 staining was predominantly observed in ESCC patients. ESCC patients with high Rad51 expression had significantly decreased survival ( P

ESCC patients with high Rad51 expression had significantly decreased survival ( P  &lt; 0.001) combined with increased tumor size ( P  = 0.034) and lymph node metastasis ( P  = 0.039). Rad51 overexpression promoted, while its knockdown attenuated, esophageal cancer cell viability through cell cycle entry and migration/invasion via epithelial–mesenchymal transition. Moreover, Rad51 overexpression increased colony formation in vitro and tumor growth in vivo.
