Figure 2From: MicroRNA-125b upregulation confers aromatase inhibitor resistance and is a novel marker of poor prognosis in breast cancer Deregulated microRNA expression profiles associated with aromatase inhibitor resistance. Dendogram of 45 micro RNA (miRNA) probe sets deregulated at the basal level in the Res-Let and Res-Ana cells as compared with the MCF-7aro cells in two independent cell cultures (replicates 1 and 2). Using the Cluster and TreeView software packages, the miRNAs were ordered according to their degree of similarity after hierarchical clustering of their expression profiles. Each column represents a cell line replicate, and each row represents a miRNA. Expression levels above the median are presented in red, and those below are shown in green. Red asterisks represent miRNAs previously described as associated with estrogen receptor (ER)/estrogen signaling, ER activity, breast cancer or endocrine resistance [16,42].Back to article page
