Sanguinarine Inhibits Cell Growth in EBV-Positive Diffuse Large B-Cell Lymphoma

To investigate the effects of Sanguinarine (SAG) on the progression of diffuse large B-cell lymphoma (DLBCL) and to explore its underlying mechanism, this study utilized Epstein–Barr virus (EBV)-positive DLBCL cell lines, FARAGE, and GM12878S. Cell counting kit-8 and bromodeoxyuridine assays were used to assess the effects of SAG on the cell proliferation. Flow cytometry and immunoblotting were employed to analyze cell cycle arrest and apoptosis. Additionally, the molecular mechanism was explored through further immunoblotting analysis of the mechanism. SAG suppressed the growth of EBV-positive DLBCL cells. Furthermore, SAG induced cell cycle arrest and promoted apoptosis in these cells. Mechanistically, SAG suppressed the Wnt/β-catenin pathway, thereby suppressing DLBCL progression in vitro. SAG effectively inhibits cell growth and induces apoptosis in EBV-positive DLBCL via Wnt/β-catenin pathway, offering potential therapeutic insights for this lymphoma subtype.
