Figure 1. D-galactose induces elevated inflammatory signature. (A) Levels of inflammatory cytokine IL-6 and TNFα in serum samples collected from control mice and those treated with D-galactose (n = 3); (B) The area of lymph nodes in the mammary glands from control and D-galactose-treated mice (n = 5); (C) Quantification of p-STAT5 staining in mammary glands from control and D-galactose-treated mice (n = 4). Scale bars, 50 μm. Asterisks, significant difference between control and D-galactose (*P < .05, **P < .01).
