Fig 3. Up-regulation of Nrf2 in normal endometrial glandular cells was directly correlated with increased expression of MMP9, and thus caused significantly stronger migration ability of primary cultured glandular cells.

A and B, the mRNA levels of Nrf2 and MMP9 in control and tBHQ groups were measured; C, higher protein levels of Nrf2 and MMP9 in tBHQ group is shown by western blot; D, glandular cells were undergone scratch test, while the wound healing changes were recorded between two groups at 0h,24h,48h; E, The variation between groups is shown in the line chart (p<0.05).
