For example, miRNA-642b-3p, miRNA-1202-5p, miRNA-1207-5p, miRNA-4270-5p, and miRNA-4281-3p were all shown to be elevated in the plasma of stage I BC patients compared to stage IV, and the expression of those miRNA panels was somewhat higher in the HER2-BC and TNBC compared to those who have the luminal subtype [[139], [140], [141]]. Here, ERBB2 is linked to breast cancer.
