In addition, the prognostic value of the candidate miRNAs was determined in ER-/LNN breast cancer," researchers in Netherlands report. "Unsupervised analysis in a prescreening set of 38 patients identified three subgroups predominantly driven by three miRNA signatures: an ER-driven luminal B-associated miRNA signature, a stromal miRNA signature, and an overexpressed miRNA cluster located on chromosome 19q23, but these intrinsic miRNA...
