Effects of GAE upon mRNA expression of NF-κB and p38. NGF differentiated-PC12 cells were treated with GAE at 0.25%, 0.5% or 1%, and followed by using H2O2 to induce cell injury. Normal group had no GAE or H2O2. Control group had no GAE, but with H2O2. Data are mean ± sd (n = 7). a-dValues among bars without a common letter differ, P < 0.05.
