SHP abrogates the BMP6 effect on iron metabolism through inhibition of hepcidin gene expression in mice.
(a–d) C57/BL6 mice were injected with Ad-GFP (n = 4 per group, 5.9 × 109 pfu) or Ad-Flag-SHP (n = 5 per group, 5.9 × 109 pfu) via the tail-vein, and treated with Vehicle or BMP6 (500 μg/kg, i.p.) for 6 h at day 5 after the infection. (a) Serum iron level. (b) Q-PCR analysis showing hepcidin and SHP mRNA levels in liver. (c) Serum hepcidin levels. (d) Western blot analysis showing SMAD1/5/8 phosphorylation and SHP expression in liver. (e) Western blot analysis showing FPN expression in spleen (top). Graphical representation showing FPN expression (bottom). Data are presented as means ± SD. Arrows show locations of molecular weight markers. The western blot images were cropped with a grey cropping line. All gels for western blot analysis were run under the same experimental conditions. **P < 0.01, ***P < 0.001 by two-tailed Student t-test.
