Results are as followed:1 Exposure of HELF cells to BP caused c-Jun activation,and increased the activity of MAPK,PI-3K,p53 and cyclin D1 pathway.2 BP-induced c-Jun activation was inhibited by dominant negative mutants of extracellular signal-regulated protein kinase or c-Jun NH_2-terminal kinase,but not by p38,impling that JNK and ERK pathways medicate c-Jun activation induced by BP.3 Overexpression of dominant-negative mutants PI-3K and Akt potently blocked phosphorylations of c-Jun and ERK,but not JNK in response to BP,suggesting that PI-3K/Akt pathway positively regulates BP-induced c-Jun activation through ERK.4 Inhibition of p53 by its chemical or molecular inhibitor markedly increased the phosphorylation levels of c-Jun,Akt and ERK upon BP stimulation,indicating that p53 negatively medicates BP-induced c-Jun activation through PI-3K/Akt/ERK pathway.5 The cell lines expressed TAM67 exhibits no significant affecting normal cell growth properties.6 TAM67 was able to significantly block G_1-S transition and subsequent cell proliferation,suggesting that c-Jun is essential for cell cycle alternations elicited by BP.7 Overexpression of TAM67 impaired BP-induced cyclin D1 activation,decreasing expression of E2F1 and pRb,indicating that c-Jun participates in the modulation of BP-induced activation of cyclin D1/pRb/E2F1 pathway.8 Stably expression of TAM67 led to the increases in the expression levels of p53 and p21,elevating phosphorylation level of p53,clearly indicating that c-Jun regulates p53/p21 pathway activation induced by BRCollectively,PI3K/Akt/ERK pathway mediated BP-induced c-Jun activation through p53-dependent mechanism.
