NANOG and neoplasm: The analysis of miRNA expression in tumour samples stratified according to NANOG expression demonstrated that most miRNAs were differentially expressed between NANOG H/L (401 miRNAs), followed by NANOG M/L (321 miRNAs) and by NANOG H/M (97 miRNAs) (Fig. 1C and Additional file 3: Table S3).
