Are global DNA methylation patterns in Barrett 's esophagus , dysplastic Barrett 's , and esophageal adenocarcinoma associated with BMI , gender , and tobacco use?
Our findings suggest obesity and tobacco smoking may influence DNA methylation in the esophagus and raise the possibility that these risk factors affect the development of BE, dysplastic BE, and EAC through influencing the epigenetic status of specific loci that have a biologically plausible role in cancer formation.
Apart from a transient and clinically insignificant decrease in total protein S, we found no prothrombotic changes after normalization of Hb from subnormal levels. Our findings indicate that rHuEpo treatment may aim at normalizing Hb levels without significant effects on haemostatic parameters in patients with chronic renal failure compared to patients with subnormal Hb levels.
