FIGURE 3.

Transcription activity of HEXB promoters in mouse SIM-A9 and human C20 microglia cells. HEXB promoter-driven dual LG reporters were transfected into mouse SIM-A9 (A) or human C20 (B) microglial cells. Supernatants were collected 72 h later and subjected to luciferase assays. Luciferase levels were normalized to empty vector, *p < 0.05; **p < 0.01; compared with empty vector transfection control (One-way ANOVA, n = 4). #p < 0.05; ##p < 0.01, compared with cells with indicated groups (t-test, n = 4). m, mouse; h, human; mk, monkey.
