Figure 5: Relative gene expression in diabetic foot ulcers (solid bar), pressure ulcers (grey bar) and acute wound (open bar) of FOXO3 (A), SIRT1 (B) and SOD2 (C). Gene expression was assessed by semi-quantitative RT-PCR and normalized to ribosomal subunit 18S mRNA. Data are presented as mean ± standard deviation. *p< 0.05.
