PKC, not Akt, regulates LPA-induced NF-κB activation. Bcl10+/− or Bcl10−/− MEFs were treated for 1 h with the PKC inhibitor rottlerin (Ro, 3 μM) (A) or the PI3K inhibitor wortmannin (WM, 1 μM) (B) before stimulation with 10 μM LPA for the indicated times. Cell extracts were subjected to immunoblotting with antibodies against IκB-α, Bcl10, phospho-Akt, or β-actin as a loading control. Experiments were repeated independently three times.
