Abstract

In recent years, neutrophil gelatinase‑associated lipocalin (NGAL) has been considered to be a key molecule in different cancer types and its carcinogenesis may be related to the NGAL/MMP‑9 complex. However, its expression pattern and role in nasopharyngeal carcinoma (NPC) has rarely been reported. In the current study, 158 tumor tissues from NPC patients were collected and immunohistochemistry was performed to determine the NGAL protein expression, to investigate the correlation between its expression and clinical and pathological parameters using Chi square analysis. Furthermore, by over‑expressing NGAL in NPC cell lines, biological alteration of NPC cells with respect to cell proliferation, migration and invasion was analyzed. Results suggested that high expression of NGAL predicts better prognosis and longer survival. Overexpression of NGAL significantly reduced the proliferation and migration of NPC cells, and induced the apoptosis by activating caspase 3, 8 and 9, and blocking epithelial‑mesenchymal transition by inhibiting mothers against decapentaplegic homolog 2/3 phosphorylation.
