TWEAK induces the expression of multiple inflammatory mediators in cardiac fibroblasts in part via TRAF3IP2. Silencing TRAF3IP2 by lentiviral shRNA (moi0.5 for 48 h) inhibited TWEAK (10 ng/ml for 2 h)-induced cytokine, chemokine, growth factor and adhesion molecule mRNA expression (RT-qPCR, A). Further, silencing TRAF3IP2 reduced TWEAK-induced cytokine and chemokine secretion (ELISA, B) and protein expression of adhesion molecules (Immunoblotting, C). C, A representative image from three independent immunoblot experiments with similar results is shown at the top with summarized semi-quantification of intensity of immunoreactive bands by densitometry from all three experiments in the respective bottom panels. A, B, n = 6, C, n = 3. A-C, *P < at least 0.01 versus untreated, †P < 0.05 versus TWEAK, §P < 0.05 versus Untreated.
