PGR and neoplasm: Similarly, four miRNA transcripts (miR-520g, miR-377, miR-527-518a, miR-520f-520c) were identified that predicted tumour PR status with 100% accuracy, and HER2/neu status was predicted with 100% accuracy by a signature of five miRNAs (miR-520d, miR-181c, miR-302c, miR-376b, miR-30e) (Table 3).
