Erratum to “Metformin affects macrophages’ phenotype and improves the activity of glutathione peroxidase, superoxide dismutase, catalase and decreases malondialdehyde concentration in a partially AMPK-independent manner in LPS-stimulated human monocytes/macrophages”

On the final steps of figure preparation the graphics technician made an incorrect attachment of blots into Fig. 7, which probably resulted from relatively low resolution of images.
