title: The up-regulation expression of APRIL is a marker of glottic malignant disease.
abstract: A proliferation-inducing ligand (APRIL) is a member of the tumor necrosis factor (TNF) family. Recent studies have implied that APRIL is closely related to solid tumors and hematological tumors, indicating that APRIL could be a potential marker to diagnose glottic malignant disease. The purpose of this study was to investigate the difference of the APRIL mRNA and protein expression in glottic malignant disease, corresponding adjacent non-neoplastic tissues and glottic benign lesion, and detect the influence of different clinical parameter in glottic carcinoma. The APRIL mRNA expression in the glottic carcinoma, corresponding adjacent non-neoplastic tissues and glottic polypus tissue samples from patients was detected by qRT-PCR. Moreover, we studied the APRIL protein expression in pathological sections of other patients with glottic carcinoma or glottic polypus using immunohistochemistry. All the patients with different clinical parameter underwent surgery. Using qRT-PCR, we revealed an up-regulation of APRIL mRNA expression in glottic carcinoma as compared to glottic polypus and corresponding adjacent non-neoplastic tissues, but no significant difference with T stages, histopathological differentiation grade or lymph node metastasis in glottic carcinoma. The result of the immunohistochemistry was the same, with no influence of different clinical parameter in glottic carcinoma. These results strongly suggest that APRIL could be a potential diagnosed marker to distinguish glottic malignant disease from glottic benign lesion, and it may play an important role in the development of glottic malignant disease.
