Esophageal squamous cell carcinoma (ESCC) still remains the leading cancer-caused mortality in northern China, in particular in areas nearby Taihang Mountain. Late-stage diagnosis of ESCC increases the mortality and morbidity of ESCC. Therefore, it is imperative to identify biomarkers for early diagnosis, monitoring of tumor progression and identifying(More)
The striking 3-4:1 male predominance of esophageal squamous cell carcinoma (ESCC) has not yet been well explained. Our hypothesis is that the changes in level of estrogen and/or subtype of estrogen receptor (ER) may exert a protective factor in esophageal carcinogenesis and prognosis of ESCC. Radioimmunoassay (RIA) was used to determine the serum level of(More)
Owing to their sessile nature, plants have evolved sophisticated genetic and epigenetic regulatory systems to respond quickly and reversibly to daily and seasonal temperature changes. However, our knowledge of how plants sense and respond to warming ambient temperatures is rather limited. Here we show that an increase in growth temperature from 22 °C to 30(More)
Esophageal cancer (EC) persists to be a leading cancer-related death in northern China. Clinical outcome of EC is the most dismal among many types of digestive tumors because EC at early stage is asymptomatic. The current study used 2-DE-based proteomics to identify differentially expressed proteins between esophageal cancer cell lines and immortal cell(More)
The aim of this study was to identify novel biomarkers for the diagnosis of, and potential therapeutic targets for, hepatocellular carcinoma (HCC). Multilectin affinity chromatography was used to enrich N-linked glycoproteins from nontumorous liver and HCC tissues followed by 2DE and protein identification by MS. Twenty-eight differentially expressed(More)
Esophageal cancer (EC) is one of the six most common cancers across the world. The striking 3-4: 1male predominance of esophageal squamous cell carcinoma (ESCC) has not yet been well explained. Our hypothesis is that the changes in level of estrogen and/or subtype of estrogen receptor (ER) may exert a protective factor in esophageal carcinogenesis and thus(More)
AIMS The asymptomatic nature of early-stage esophageal squamous cell carcinoma (ESCC) results in late presentation and consequent dismal prognosis This study characterized 14-3-3σ protein expression in the multi-stage development of ESCC and determined its correlation with clinical features and prognosis. MATERIALS AND METHODS Western blot was used to(More)
BACKGROUND & OBJECTIVE Our recent study on proteomics for esophageal cancer has indicated the importance of Annexin II as a promising protein to distinguish esophageal cancer patients from healthy subjects. This study was to detect the expression of Annexin II in esophageal squamous cell carcinoma (ESCC) and adjacent tissues, and to explore the role of(More)
Multidrug resistance (MDR) is one of the main causes leading to the failure in cancer treatment. Differential proteins between esophageal squamous cell carcinoma (ESCC) cell line EC9706 and its cisdiamminedichloroplatinum (CDDP)-resistant subline EC9706/CDDP revealed by quantitative analysis may provide deeper insights into the molecular mechanisms of MDR(More)
AIM To further understand the molecular basis for gastric cardia carcinogenesis and to provide etiological clues. METHODS Endoscopic mucosa biopsy and histopathological examinations were made on 37 subjects from a high incidence area for both esophageal and gastric cardia carcinomas in northern China. All the biopsy samples were fixed in 850 ml. (-1)L(More)
