A–B: Effects of Src-, PI-3K-, AKT-inhibitors and IGF-1 or/and PDGF-bb on IL-1β-stimulated phosphorylation of NF-κB in chondrocytes.


<p>Primary chondrocytes were either stimulated with 10 ng/ml IL-1β, pre-stimulated with PP1 (10 µM), wortmannin (20 nM) and SH-5 (10 µM) for 1 h (A), or with 10 ng/ml IGF-1, 10 ng/ml PDGF-bb or a combination of both growth factors (5 ng/ml each) for 12 h (B) and then incubated with IL-1β for 30 min. Nuclear extracts were subjected to 10% SDS-PAGE (500 ng protein per lane), transferred to nitrocellulose membranes and then probed using an antiserum reactive with an anti-phospho-p65 or anti-PARP polyclonal antibody (housekeeping control). Similar results were obtained in three independent experiments.</p
