ERBB2 and breast neoplasm: Theutilisation of miRNA microarray has several benefits versus formal literaturereview: Microarray records measurements of the relative concentrations of miRNAexpression profile within a pre-selected tissue of interest73,74 (ie, HER2+breast tumour tissue, previously acquired from core biopsy), which subsequentlyfacilitates an increased likelihood of identifying molecularly appropriate targets,which increases the possibility of yielding clinically pertinent results.
