Zebrafish PLAAT1 negatively regulates IFN expression and signaling. (A, B) Overexpression of plaat1 suppressed the activity of IFNφ1 (A) or ISRE (B) luciferase reporter induced by SVCV infection or poly (I:C). EPC cells were seeded in 24-well plates and transfected with IFNφ1pro-Luc (250 ng) or ISRE-Luc (250 ng) plus pRL-TK (25 ng) and Flag-plaat1 or pcDNA-3.1 (empty vector, 250 ng). After 24 h, the cells were infected with SVCV (3.16 × 10⁶ TCID₅₀/mL) or transfected with poly (I:C) (2 μg/mL). After 24 h, luciferase reporter activity was analyzed. (C) The EPC cells were transfected with ISRE-Luc (250 ng) plus pRL-TK (25 ng) and Flag-plaat1or pcDNA-3.1 (empty vector, 250 ng). At 24 h post-transfection, cells were treated with PBS or IFNφ1 protein (100 ng/mL) for 6 h. Data are shown as mean ± SEM (n=3). *P<0.05 is considered significant difference.
