Similarly to FPN1, the level of other analyzed protein Fn was negatively associated with IRP1 mRNA level but positively correlated with miR-133a level (r = −0.97, p < 0.001 and r = 0.56, p = 0.011, respectively) in patients having lymph nodes invaded by the tumor, which was shown in Fig. 6. This evidence concerns the gene ACO1 and neoplasm.
