Fig 1. The mRNA expression levels of iron-metabolism-related genes in cancer and normal bladder specimens from same patient (A) and in MCF10A and MCF7 (B).

The expression levels of target genes were normalized with gapdh, a housekeeping gene. Data are expressed as means ± S.D. in two independent experiments. Statistical significance of difference is indicated by *p <0.05, **p <0.005 determined with Student’s t-test.
