Iron Reduces M1 Macrophage Polarization in RAW264.7 Macrophages Associated with Inhibition of STAT1

Figure 1

Differential expression of iron metabolism-related genes in M1 macrophages. (a) Hamp2, (b) FPN, (c) FtH, (d) FtL, (e) IRP1, and (f) IRP2 mRNA levels in 24 h cells after polarization. The expression was normalized to β-actin and then expressed in relation to unstimulated macrophages, arbitrarily defined as 1. Data are mean ± SD for three independent experiments. (uns: unstimulated macrophages; , ).
