To verify this speculation , we first confirmed the transcriptional changes of several key iron homeostasis - related genes , such as Tfrc , Trf , and Lcn2 , using quantitative PCR , and found that an iron ion chelator , desferrioxamine , could alleviate the transcriptional alterations of two typical genes , Tfrc and Lcn2 .
