To examine whether DLEU1 gene affects cell proliferation and programmed cell death in BL, Raji cells with or without DLEU1 knocked out (DLEU1-KD or WT), were plated into 48-well plates and evaluated every 24 hours for cell proliferation by MTS assay and programmed cell death by Caspase 3/7 assay. The gene discussed is CASP3; the disease is Burkitt lymphoma.
