Re-evaluation of SERPINE1 mRNA expression in fibroblasts under hypoxia. Two different gene expression assays were applied to confirm SERPINE1 overexpression relative to POLR2A in fibroblasts cultured under hypoxia compared with fibroblasts cultured under normal oxygen conditions. Shown are results from cell line F-18. * = p < 0.05 (three independent experiments).
