Protein levels of MnSOD, TGF-β, Nrf2 and NF-κB in control and irradiated MnSOD^tet/tet cell lines. MnSOD^+/+, MnSOD^tet/+, MnSOD^tet/tet and MnSOD^−/− cell lines were incubated in the presence or absence of doxy for 24 h, then irradiated to 0 or 10 Gy. Six hours later cells were harvested and proteins were subjected to Western analysis for MnSOD, TGF-β, Nrf2 and NF-κB. Expression of GADPH was used for a loading control.
