Association between disease-specific survival and the expression levels of miR-10b* and three of its target genes (BUB1, PLK1 and CCNA2). (a) Kaplan-Meier analysis based on the METABRIC miR expression data (REF). Survival of the 370 patients with the highest (top third) expression levels of miR-10b* (red line) was compared to the 370 patients with the lowest expression levels (blue line). The plot was truncated at 15 years, p-value is indicated in the title. (b-d) Kaplan-Meier analysis based on the METABRIC mRNA expression data (REF). The two compared groups are 565 patients with the highest (top third) expression levels of each target gene (red line) versus 565 patients with the lowest (bottom third) expression levels (blue line). The plot was truncated at 15 years, p-values are indicated in the titles. (Biagioni et al., Cell Cycle, 2013)

• miRNA expression profile on 61 breast samples: tumor and peritumor from the same patient

Confirmed deregulation of many microRNAs already reported in the

literature

New microRNAs discovered which expression is modulated in the transformed status

• 5 microRNAs (miR-425, miR-454, miR-301a, miR-10b* and miR-139-5p) are

commonly deregulated among different subtypes

• microRNA-10b* Is downregulated in tumor versus peritumor tissue by hypermethylation

of its regulatory regions Controls cell cyle and proliferation targeting three key components: BUB1,

PLK1 and CCNA2

When injected in xenografted human breast tumors, it impairs tumor growth
