Comparative gene expression levels between young and old erythrocytes (RBCs). Expression of eight target genes was normalized to β-actin as a reference gene and then related to the expression of the respective gene in the original erythrocyte sample taken before the fractionation procedure. Gene abbreviations are hbα-1, hemoglobin α-1; hbα-4, hemoglobin α-4; gbx, globin x1; β3b-ar, β3b-adrenergic receptor; β-nhe, β-Na+/H+-exchanger; hif1a, hypoxia inducible factor 1a; gapdh, glyceraldehyde-3-phosphate dehydrogenase; hsp70, inducible heat shock protein 70 kDa. Statistically significant differences between means of young and old erythrocyte fractions is shown by *p < 0.05.
