Identification of a truncated cystatin SA-I as a saliva biomarker for oral squamous cell carcinoma using the SELDI ProteinChip platform
چکیده انگلیسی

New and more consistent biomarkers of oral squamous cell carcinoma (OSCC) are needed to improve early detection of the disease and to monitor patient management. The aim of this study was to detect new OSCC tumor markers in saliva. Unstimulated saliva, collected from patients with primary stage I OSCC as matched pre-and post-treatment samples, was used in the analysis. A surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF) ProteinChip system was used to screen for differentially expressed proteins in the saliva samples. This analysis revealed 26 proteins with significantly different expression levels in the pre-and post-treatment samples (P < 0.05). A 14 kDa protein detected in pre-treatment saliva from the OSCC patients was identified as a truncated cystatin SA-I, with deletion of three amino acids from the N-terminus. The authors propose that ProteinChip analysis may provide a reliable screening test for early diagnosis of OSCC and that truncated cystatin SA-I might be a useful tumor biomarker for OSCC.
