摘要: Diagnostic oncoproteomics is an emerging field; at present, studies on evaluation of prognostic utility potential biomarkers identified using proteomic techniques are limited. Analysis with isobaric mass tags (iTRAQ) by multidimensional liquid chromatography−mass spectrometry (LC−MS/MS) to identify proteins that differentially expressed in human head-and-neck/oral squamous cell carcinomas (HNOSCCs) versus noncancerous head-and-neck tissues has led the discovery, identification, and verification consistently increased expression a panel proteins, including stratifin (14-3-3σ) YWHAZ (14-3-3ζ), may serve as cancer biomarkers. Herein, we describe these two candidate for carcinoma (HNOSCC). To determine clinical significance tumorigenesis, expressions were analyzed HNOSCCs (51 cases) nonmalignant (39 immunoh...
