- _4 wasQuotedFrom 12711606 provenance.
- _4 value "First, H2O2 activated Syk in KBM-5 cells; second, H2O2 failed to activate NF-kappaB in cells that do not express Syk protein; third, overexpression of Syk increased H2O2-induced NF-kappaB activation; and fourth, reduction of Syk transcription using small interfering RNA inhibited H2O2-induced NF-kappaB activation. We also showed that Syk induced the tyrosine phosphorylation of IkappaBalpha, which caused the dissociation, phosphorylation, and nuclear translocation of p65. Thus, overall, our results demonstrate that H2O2 induces NF-kappaB activation, not through serine phosphorylation or degradation of IkappaBalpha, but through Syk-mediated tyrosine phosphorylation of IkappaBalpha" provenance.
