The SU-DHL-4 cell line, established in 1982, is a well-characterized model of diffuse large B-cell lymphoma (DLBCL). Initially derived from the lymph node biopsy of a patient with DLBCL, SU-DHL-4 cells have been extensively utilized in research aimed at understanding the pathogenesis and therapeutic responses of DLBCL. These cells exhibit characteristic features of DLBCL, including the expression of B-cell markers and the presence of chromosomal abnormalities commonly observed in this malignancy.
The development of the SU-DHL-4 GFP reporter cell line represents a significant advancement in DLBCL research. This reporter cell line incorporates a green fluorescent protein (GFP) reporter gene into the SU-DHL-4 cellular genome, allowing for the visualization and tracking of specific cellular processes or molecular events in real-time. By exploiting the unique fluorescence properties of GFP, researchers can monitor cellular behaviors, such as proliferation, migration, and apoptosis, in response to various experimental conditions or therapeutic interventions. Additionally, the SU-DHL-4 GFP reporter cell line serves as a valuable tool for high-throughput screening assays and drug discovery efforts targeting DLBCL.
The researchers investigated the impact of Raji-derived extracellular vesicles (Evs) on lymphoma cells, with a focus on proliferation, invasion, autophagy, and apoptosis. Methods included Cell Counting Kit-8 (CCK-8) assays, Transwell experiments, microscopy, Western blotting, and flow cytometry. They analyzed miR-106a expression, downregulated it in Raji cells, and isolated resulting Evs (Evs-in-miR-106a). The binding relationship between miR-106a and Beclin1 was validated through RNA pull-down and dual-luciferase reporter gene assays. Overexpression of Beclin1 in SU-DHL-4 and Farage cells was performed, assessing autophagy and apoptosis in SU-DHL-4 cells. Tumorigenicity assays in nude mice validated the effects of Raji-Evs. Results demonstrated that Raji-Evs promoted lymphoma cell proliferation and invasion by upregulating miR-106a, which was reversed upon miR-106a knockdown. Furthermore, Raji-Evs-carried miR-106a targeted Beclin1, inhibiting autophagy and apoptosis, thus facilitating tumor growth in vivo. This study elucidated the mechanism by which Raji-Evs inhibit lymphoma cell autophagy and apoptosis while promoting cell growth via the miR-106a/Beclin1 axis.
