Erratum

Since publication of our article [1] we have noticed that an error was introduced during the assembly of Fig. 1d (Fig. 1 here), resulting in the duplication of two panels. Specifically, lanes 7–12 probed for TIA-1 are the same as lanes 13–18 also probed for TIA-1. In addition, lanes 7–12 probed with Actin are the same as lanes 19–24 probed with Actin [1]. We sincerely regret this error. The corrected figure appears below.

siRNA transfected HeLa cells were treated with or without SA and collected 1 h post-SA. Cytoplasmic extracts were digested with 0, 0.1, 0.2, 0.4, 0.8 or 1.6 mg/ml Proteinase K and assayed by immunoblot. TIA-1 is more protease-sensitive when TDP-43 is absent (arrows). Data is representative of 3 independent experiments
