Effects of CP treatment on cellular antioxidant defense gene expressions following mastitis pathogen challenges in MAC-T cells. Quantitative PCR analysis of cellular antioxidant defense genes, HO-1 (a), Txnrd-1 (b), and GCLM (c), showing gene expressions after 6 h incubation of MAC-T cells with each different mastitis pathogen, including proinflammatory cytokine (TNF-α 25 ng/mL), bacterial cell wall components (LPS, 1 μg/mL; LTA, 10 μg/mL), and heat-killed mastitis strains (E. coli and S. aureus, 107 particles/mL). Ct values of target genes were normalized to the value of β-actin and relative gene expressions in TNF-α control group were arbitrarily set to one. The data are shown as mean ± SD from three independent experiments and were analyzed by one-way ANOVA with the Student-Newman-Keuls method. The means with different superscripts are significantly different ().
