Effects of GAE upon MMP, measured as MFI; DNA fragmentation, measured as enrichment factor; and Ca2+ release. NGF differentiated-PC12 cells were pre-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-eValues in a column without a common letter differ, P < 0.05.
