BACKGROUND Metallothionein 3 (MT3) maintains intracellular metal homeostasis and protects against reactive oxygen species (ROS)-induced DNA damage. In this study, we investigated the epigenetic alterations and gene expression of the MT3 gene in esophageal adenocarcinomas (EACs). METHODS AND RESULTS Using quantitative bisulfite pyrosequencing, we detected unique DNA methylation profiles in the...

Esophageal adenocarcinoma (EAC) has become the dominant type of esophageal cancer in United States. The 5-year survival rate of EAC is below 20% and most patients present with locally advanced or widespread metastatic disease, where current treatment is largely ineffective. Therefore, new therapeutic approaches are urgently needed. Improvement of EAC patient outcome requires well-characterized ...

Ehrenwörtliche Versicherung Diese Dissertation wurde selbständig und ohne unerlaubte Hilfe erarbeitet. Acknowledgements I would like to thank my supervisor, Prof. Jens Michaelis for creating a highly motivating scientific environment, lots of freedom but also the pressure he put on me. I am deeply grateful for his support and understanding of my never-ending trips, which he sometimes called " u...

Fish oil supplies worldwide have declined sharply over the years. To reduce the use of fish oil in aquaculture, many studies have explored the effects of fish oil substitutions on aquatic animals. To illustrate the effects of dietary lipids on Chinese mitten crab and to improve the use of vegetable oils in the diet of the crabs, 60 male juvenile Chinese mitten crabs were fed one of five diets f...

BACKGROUND Carcinoma of the esophagus has a high case fatality ratio and is now the 6th most common cause of cancer deaths in the world. We previously conducted a study to profile the expression of miRNAs in esophageal adenocarcinoma (EAC) pre and post induction therapy. Of the miRNAs differentially expressed post induction chemoradiation, miR-145, a known tumor suppressor miRNA, was upregulate...

PURPOSE The melanoma-associated antigens (MAGEs) are tumor-specific antigens recognized by cytotoxic T lymphocytes. In this study, expression of MAGE family A members was evaluated during the development of esophageal adenocarcinoma (EA) as potential targets for immunotherapy. EXPERIMENTAL DESIGN MAGE-A mRNA expression was evaluated in 46 samples including Barrett's metaplasia (BM), dysplasia...
