The presence of LILRA3 has limited effects on U937 cell apoptosis
The impact of LILRA3 on apoptosis has not been reported. After culturing for 48 hours, cells were harvested and stained with 7-AAD kit, and the apoptosis ratio was calculated for GFP+ cells. According to the data shown in Figure 3D and 3E, we conclude that although LILRA3 obviously decreased the late apoptosis rate compared with the null vector cells (3.64%±0.11% vs. 4.41%±0.20%, p < 0.01), it had little effect on early apoptosis and total apoptosis frequencies (p > 0.05). This result indicates that LILRA3 is not involved in regulating apoptosis in U937 cells.
