To further examine whether the GE alterations identified by the microarray analysis also occur at the protein level, we performed IHC analysis for selected RPs, including RPL26, that has been associate with Diamond-Blackfan anaemia and tumorigenesis (32, 33); RPS27 overexpresses in several tumours and RPS29, which exhibits cell-specific expression in lymphoid cell types (34–36). This evidence concerns the gene RPL26 and neoplasm.
