Decreasing expression of glucose-regulated protein GRP78/BiP as a significant prognostic predictor in patients with advanced laryngeal squamous cell carcinoma

摘要

Background. The immunoglobulin heavy chain binding protein (BiP)/glucose-regulated protein 78 (GRP78) is important in the endoplasmic reticulum stress, and is highly expressed in various human cancers. The clinical and pathological features of GRP78/BiP are unclear in patients with advanced laryngeal squamous cell carcinoma (SCC). The purpose of this study was to investigate the clinicopathological significance of GRP78/BiP as a prognostic marker for laryngeal SCC.
