Activity of microglia-related promoters, including HEXB and CD68, in the induction of gene transcription in HEK293T cells. (A) Different sizes of mouse, human, or monkey HEXB promoter-driven dual-LG reporters were transfected into HEK293T cells in 96-well plate. At 72 h after transfection, gdLuc levels in culture media were measured to determine the HEXB promoter activity. Cells transfected with plasmids driven by other microglia-related promoters, such as CD68, were also included, and transcription activity were determined by measuring luciferase levels in culture supernatants. (B) Representative images after transfection are shown (scale bar, 100 μm). ****p < 0.0001, compared with empty vector transfection controls (One-way ANOVA, n = 4). #p < 0.05; ##p < 0.01; ###p < 0.001, compared with indicated groups (t-test, n = 4). m, mouse; h, human; mk, monkey.
