Examples of patterns of gene expression in human terminal erythroid differentiation. Integrated genome viewer of RNA-seq tracks from representative genes. (A) FOX03. (B) STOM, stomatin. (C) PKLR, pyruvate kinase. (D) Signal transducer and activator of transcription 5A. (A-B) Genes from group 1, genes with increasing expression during differentiation. (C-D) Genes from group 3, genes with decreasing expression during differentiation. The tracks show read coverage values at each base normalized to the number of sample total reads/1 000 000. ncRNA, noncoding RNA.
