(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).

Intratumoral delivery of miR-10b* impairs its targets expression
Intratumoral delivery of miR-10b* associates with lower expression of proliferative markers
miR-10b* has a key role in controlling breast cancer cell proliferation in vivo
• 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
