(A) Immunoblot for TFEB, TFE3, and proteins corresponding to their transcriptional target genes in Tsc2−/− MEFs treated for two days with control siRNA, siTfeb, or siTfe3.
(B,C) 14C-TGs assayed by pulse-chase with [1-14C]-oleate tracer (6 h) in Tsc2−/− MEFs treated as in (A) followed by chase in cold medium for 16 hrs with vehicle or 250 nM torin1, graphed as mean ± SD relative to control siRNA-treated cells (B) and relative to vehicle-treated cells (C), n=3.
Statistical analysis by one-way ANOVA (B) and two-way ANOVA (C). n.s., not significant.
