Abstract |
Intracellular vesicle trafficking is the principal transportation system in eukaryotic cells, and is considered to be involved in a variety of processes related to cell proliferation. A protein named alpha-taxilin has been identified as a binding partner of the syntaxin family, which coordinates intracellular vesicle trafficking. To clarify the role of alpha-taxilin in renal cell carcinoma (RCC), we investigated alpha-taxilin protein expression in clear cell RCC tissues. We analyzed alphataxilin protein in matched sets of tumor and non-tumor tissues from the surgical specimens of 52 Japanese RCC patients by Western blotting. We also studied the relation between alpha-taxilin protein expression in tumor tissues and various clinicopathological features. The alpha-taxilin protein level was higher in tumor tissues than in non-tumor tissues (P < 0.05). Increased expression of alpha-taxilin protein in primary tumors was related to local invasion (P < 0.001), pathological vessel invasion (P < 0.001), and metastasis (P < 0.0001). Kaplan-Meier plots of survival for patients with low versus high alpha-taxilin expression revealed that high expression in tumor tissues was associated with shorter overall survival in all patients (P < 0.05) and with shorter disease-free survival in patients without metastasis (P < 0.01). These findings suggest that alpha-taxilin influences the metastatic and invasive potential of RCC.
