Fig. 2From: Activation of antioxidant defences of human mammary epithelial cells under leptin depend on neoplastic stateCharacterization of antioxidant response time course in the presence of leptin (10, 100 ng/ml) in human mammary epithelial cells. a: Antioxidant response of HMEC. b: Antioxidant response of MCF-7. c: Antioxidant response of MDA-MB-231. In terms of: 1- Total glutathione, 2- Protein thiols, 3- Glutathione reductase mRNA expression 4- Glutathione reductase catalytic activity. Values are expressed as mean ± standard deviation (n = 6). Between-groups comparison was performed by one-way ANOVA followed by the Kruskal-Wallis multiple comparison test. The significance level was set at 0.05. Statistical significance between groups is indicated by * p < 0.05, ** p < 0.01 and *** p < 0.001Back to article page
