Long-term Efficacy and Safety of Endoscopic Resection for Patients With Mucosal Adenocarcinoma of the Esophagus
2013
Background & Aims Barrett's esophagus–associated high-grade dysplasia is commonly treated by endoscopy. However, most guidelines offer no recommendations for endoscopic treatment of mucosal adenocarcinoma of the esophagus (mAC). We investigated the efficacy and safety of endoscopic resection in a large series of patients with mAC. Methods We collected data from 1000 consecutive patients (mean age, 69.1 ± 10.7 years; 861 men) with mAC (481 with short-segment and 519 with long-segment Barrett's esophagus) who presented at a tertiary care center from October 1996 to September 2010. Patients with low-grade and high-grade dysplasia and submucosal or more advanced cancer were excluded. All patien…
Cloning and characterization of the promoter of Hugl-2, the human homologue of Drosophila lethal giant larvae (lgl) polarity gene.
2007
The human lgl gene, Hugl-2 (llgl2, Lgl2), codes for a cytoskeletal protein involved in regulating cell polarity. Here, we report the identification and functional characterization of the promoter region ( approximately 1.2kb) of the Hugl-2 gene. Luciferase expression assays show a high basal Hugl-2 promoter activity in different cell lines and primary human hepatocytes. Truncations of the promoter identified a GC-rich region important for this activity. Alignment of human and mouse genomic sequences demonstrate that this is an evolutionary conserved region fcontaining putative binding sites for several transcription factors including Elk-1 and Sp-1. Mithramycin A reduces Hugl-2 expression i…
