Inflammatory role of transforming growth factor beta-1 (TGF-β1) in multistep progression of gastric oncogenesis: an immunohistochemical study

The purpose of this study was to investigate differential expression of TGF-β1 in gastric tissues resected from patients diagnosed with chronic gastritis and gastric cancer (adenocarcinoma) and elucidate the potential role of TGF-β1 in steering towards cancer promoting or cancer suppressing microenv...
