Comparison of nascent reticulocytes proteome (BMRetic) with Gautier et al²⁵ data of mature reticulocytes (CircRetic) and purified circulating erythrocytes (CircEryth). (A) Mean number of quantified proteins in each population. Statistics: 1-way analysis of variance; ∗∗∗∗P < 0001. (B) Venn diagram of quantified proteins in each population (proteins quantified in at least 1 sample). (C) Pearson correlations of log₂(protein copy numbers per cell) between each sample. (D) Mean quantity (in picograms per cell) of globins and other proteins in each population. (E) Principal component analysis of log₂(protein copy numbers per cell) of every sample (proteins with at least 70% of valid values in at least 1 condition were selected). BM, bone marrow.
