It has been reported that EBV latent membrane protein 1 (LMP1) has a resistant to the TGF-β1-mediated growth inhibition in EBV-positive gastric carcinoma cell lines (GT38 and GT39) and indicated that TGF-β1 may be a key factor for EBV reactivation and selective growth of EBV-infected epithelial cells in vivo [17, 18]. The gene discussed is TGFB1; the disease is gastric carcinoma.
