TGFB1 and gastric cancer: TGFβ3 was also a poor prognostic factor for STAD in this study, however, compared to the large amount of data available for TGFβ1, there is a lack of relevant data demonstrating the pathogenic role of TGFβ3 in tumorigenesis, so this study is an important addition to the role of TGFβ3 molecules in gastric cancer.
