1 Silica nanoparticles as an enhancer in the IL-1beta-induced inflammation cycle of A549 cells. Silicon Dioxide interleukin 1 alpha Homo sapiens
2 However, whether nano-SiO2 can increase the IL-1beta-induced inflammatory expression in A549 cells has not been tested. Silicon Dioxide interleukin 1 alpha Homo sapiens
3 The synergistic effect of nano-SiO2 and IL-1beta was observed on the new production of IL-1beta and IL-6 in A549 cells. Silicon Dioxide interleukin 1 alpha Homo sapiens
4 The Western blot results showed that nano-SiO2 can increase the expression of IL-1beta and IL-6 by promoting the phosphorylation of ERK1/2 and elevating the phosphorylation of I-kappaB by IL-1beta. Silicon Dioxide interleukin 1 alpha Homo sapiens
5 The Western blot results showed that nano-SiO2 can increase the expression of IL-1beta and IL-6 by promoting the phosphorylation of ERK1/2 and elevating the phosphorylation of I-kappaB by IL-1beta. Silicon Dioxide interleukin 1 alpha Homo sapiens
6 IL-1beta and IL-6 were induced by nano-SiO2, and the IL-1beta treatment with 20 muM of I-kappaBalpha phosphorylation inhibitor (PD98059) and 20 muM of ERK1/2 inhibitor (BAY11-7082) for 1 h was significantly lower than that of the control group in A549 cells. Silicon Dioxide interleukin 1 alpha Homo sapiens
7 Discussion and conclusion: These results indicated that nano-SiO2 had a toxic effect on A549 cells, and this effect could increase IL-1beta on the A549 cell-induced inflammatory response. Silicon Dioxide interleukin 1 alpha Homo sapiens
