DNTT and glioma: For SW1088 glioma cells, the RFU of TdT-labeled cells in the control (cells not treated with 2-ME) were considered 1, and for samples treated 24 h with 2-ME, the results were as follows: 100 pM—7.96 (±0.11); 1 nM—7.39 (±1.43); 10 nM—16.41 (±2.24); 100 nM—4.24 (±1.00); 1 μM—13.86 (±1.77); and 10 μM—18.54 (±3.05), relative to the control (Figure 3A).
