Protein expression of iron metabolism components in aging muscle. A) Representative ferritin L (19 kDa) western blot image (M=molecular weight marker, L=liver). B) (top) Representative TfR1 (95 kDa) western blot image (M=molecular weight marker, L=liver); (bottom) TfR1 protein expression in aging plantaris. *Different from 8-month old group (p<0.05); n=8–10/group. C) (top) Representative IRP1 (98 kDa) western blot image (M=molecular weight marker; L=liver); (bottom) IRP1 protein expression in aging plantaris. *Different from 8 and 18-month old groups (p<0.05); n=9–10/group. Values are mean±SEM.
