Comparison of miRNA levels in tissue and plasma. Hierarchical clustering view of the normalized expression levels of active forms of miRNA. The tissue level expression of miRNA precursors available as RPKM (reads per kilobase of transcript per million) values were obtained from TCGA RNASeq data as follows: control samples (n = 87), Triple negative breast cancer samples (n = 38) and Luminal samples (n = 120). The RPKM values of the precursor in tissue and the expression value in the current qPCR (inferred as 2-dCt (2(−ΔCt))) for circulating miRNA, were log2 transformed and auto-scaled to ensure the data are comparable
