Levels of GSH, GSH+GSSG and nuclear NF-κB. a Levels of free (GSH) and total (GSH+GSSG) glutathione in MCF-7-Snail and MCF-7-Control cells determined by luminescent assay; NLU normalized luminescence units; p-values (multiple t-test with Holm-Šidák correction): GSH = 9.98 × 10−5; GSH+GSSG = 8.46 × 10−8. b Levels of nuclear NF-κB in MCF-7-Snail and MCF-7-Control cells expressed as determined by ELISA in nuclear protein lysates; NA normalized absorbance; Error bars: SD; p = 0.0071 (Welch’s corrected t-test; **: p <0.01; ***: p <0.001)
