Esophageal squamous cell carcinoma (ESCC) is generally known to be a highly fatal cancer, and thus novel molecular targets are needed to improve its diagnosis and treatment. AJUBA has been shown to regulate cell cycle, adhesion, proliferation, apoptosis, and migration in many malignant tumors. However, the clinical significance of AJUBA in ESCC tumor metastasis remains unclear. In this study, we explored the role of AJUBA, Yes-associated protein 1 (YAP1), and matrix metalloproteinase 14 (MMP14) in the clinical presentation and survival of ESCC. Immunohistochemical staining showed higher expression of these proteins in cancer tissues than in paired adjacent tissues, and this upregulation was differently related to lymph node metastasis and TNM stage. AJUBA expression was positively correlated with that of YAP1. High expression of MMP14 was associated with reduced survival. In general, our findings reveal that AJUBA, YAP1, and MMP14 might function as oncoproteins and contribute to novel targeted therapy in ESCC.
Keywords: AJUBA; ESCC; MMP14; YAP1; clinical significance.
