Overexpression of TDP-43 accelerates IκB degradation.

<p>Cells were transfected with wild type TDP-43 expressing plasmids (tagged with mCherry) or mCherry empty plasmid (control) and were treated with 10ng/ml TNF-α for the indicated periods. Total proteins were extracted for Western blot analysis using antibodies as indicated. n = 3 independent cultures; <b>A</b>. 30 min after TNF-α treatment, the degradation of IκB occurred in both control group and TDP-43 overexpression group. <b>B</b>. Overexpression of TDP-43 facilitates the degradation of IκB within 5 minutes after TNF-α treatment.
