To investigated the role of microRNA (miRNA) let-7 and its regulation on high mobility group A2 (HMGA2) protein expression in esophageal squamous cell carcinoma (ESCC). Let-7 expressions were detected in esophageal cancer cell line Eca109, and 45 paired of fresh ESCC and normal adjacent tissues (NAT) by real-time quantitative PCR (qRT–PCR). To evaluate the(More)
Annexin A2 and Cdc42 were identified by 2-dimensional electrophoresis (2-DE) and MALDI-TOF–MS between esophageal squamous cell carcinomas (ESCC) and corresponding normal esophagus mucosa in our previous study. To assess clinico-pathological pattern and Annexin A2 and Cdc42 status with respect to cell differentiation and lymphnode metastasis in patients with(More)
The p38 mitogen-activated protein kinase (MAPK) is a member of the MAPK family, which is initially found to be activated by stress stimuli, proinflammatory cytokines, and growth factors. However, its role in the pathogenesis of esophageal squamous cell carcinoma (ESCC) is largely unkown, so we investigate the role of phosphorylated p38 (p-p38) MAPK in ESCC.(More)
Bacterial chitinases are useful in the biocontrol of agriculturally important pests and fungal pathogens. However, the utility of naturally occurring bacterial chitinases is often limited by their low enzyme activity. In this study, we constructed mutants of a Bacillus thuringiensis chitinase with enhanced activity based on homology modeling, molecular(More)
