RIPK4 sustains NF-κB activation. a RIPK4 stabilises TRAF2, RIP and NEMO in BC cells. b Western blot analysis of the K63-linked polyubiquitination levels of RIP (upper panel), TRAF2 (middle panel) and NEMO (lower panel) in the indicated cells treated with TNF-α (10 ng/mL). c Western blot analysis of IκBα expression in the indicated cells treated with TNF-α (10 ng/mL); β-actin was used as a loading control
