D, E Luciferase activity measured in WT, GCN5 KO and GCN5/TFEB DKO HEK293 cells (D), and in HEK293 cells with TFEB-WT or TFEB-3KR transfection (E). The cells were transfected or co-transfected with a TFEB-luciferase reporter. 3KR: Lys 116, Lys 274, and Lys 279 were replaced by Arg. Data information: In this Figure, data are presented as mean ± SEM; n = 3 independent experiments; *p < 0.05, **p < 0.01, ***p < 0.001, Student's t-test.
