17015749 Nair AS, Shishodia S, Ahn KS, Kunnumakkara AB, Sethi G, Aggarwal BB: Deguelin, an Akt inhibitor, suppresses IkappaBalpha kinase activation leading to suppression of NF-kappaB-regulated gene expression, potentiation of apoptosis, and inhibition of cellular invasion. J Immunol. 2006 Oct 15;177(8):5612-22.


The suppression of TNF-induced NF-kappaB activation by deguelin occurred through the inhibition of the activation of IkappaBalpha kinase, leading to sequential suppression of IkappaBalpha phosphorylation, IkappaBalpha degradation, p65 phosphorylation, p65 nuclear translocation, and NF-kappaB-dependent reporter gene expression.

Hypoxia generated mROS in hepatoma (HepG2, H35), neuroblastoma (SH-SY5Y), and colon carcinoma (DLD-1) cells, leading to hypoxia-inducible transcription factor-1alpha-dependent gene expression and c-Src activation that was prevented in cells expressing a redox-insensitive c-Src mutant (C487A). c-Src stimulation activated NF-kappaB without IkappaB-alpha degradation due to IkappaB-alpha tyrosine phosphorylation that was inhibited by rotenone/TTFA or c-Src antagonism.
The c-Src-NF-kappaB signaling contributed to the survival of cells during hypoxia as c-Src inhibition or p65 down-regulation by small interfering RNA-sensitized HepG2 cells to hypoxia-induced cell death.
