Figure 6C shows that the fluorescence expression was significantly reduced in the Lv-shIFITM3-KG1a group compared with the scrambled group. The proliferation rate of the Lv-shIFITM3-KG1a cells in the model mice was significantly slowed down. To further verify this finding, FCM analyses were conducted and detected the expressions of the AML-related immunological markers, CD33, CD123, and CD11b, in the Lv-shIFITM3-KG1a cells. Figures 6D, E show that the expression levels of CD11b, CD33, and CD123 were decreased, with statistically significant differences in comparison to the scrambled cells. This evidence concerns the gene CD33 and acute myeloid leukemia.
