"Curcumin substantially reduced the fluoride- and TPA induced IkappaBalpha degradation (XREF_FIG) and abolished the p65 phosphorylation, as assessed in cell lysates (XREF_FIG) and p65 translocation to the nuclei (XREF_FIG) after exposure to both agents."

reach
"Activation of NF-kappaB is usually associated with the induction of IkappaB phosphorylation; as expected, TPA enhanced the activation of serine 536 phosphorylated NF-kappaB p65 and serine32 phosphorylated I-kappaBalpha and caused the degradation of IkappaBalpha in ECV304 cells (XREF_FIG)."

reach
"In addition, bicyclol attenuated TPA induced IkappaB-alpha degradation."

reach
"Capsaicin pretreatment significantly suppressed TPA induced degradation of IkappaB-alpha, thereby attenuating nuclear translocation of p65."

reach
"However, some carcinogens, e.g., DMBA and 12-O-tetra-decanoylphorbol-13-acetate (TPA), degrade IkappaBalpha by its phosphorylation."

reach
"In XREF_FIG, the time courses for fluoride- and TPA induced IkappaBalpha degradation are presented."

reach
"TNF-alpha- or TPA induced IkappaBalpha kinase (IKK) activation was also blocked by these inhibitors, which slightly reversed TNF-alpha-induced but completely reversed TPA induced IkappaBalpha degradation."

reach
"As expected, TPA increased IKBalpha degradation (Additional file XREF_SUPPLEMENTARY : Figure S1B) and induced binding of p65 to kappaB-RE of MnSOD gene."

reach
"Although protocatechuic acid decreased p65-DNA binding, it did not affect TPA stimulated degradation of IkappaBalpha."

reach
"The results showed that galangin blocked TPA induced IkappaBalpha degradation by inhibiting the phosphorylation of IkappaBalpha."
