TranscriptomicsmicroRNA and cancer progression in breast tumors
miRNAs are small non-coding RNAs frequently altered in human malignancies. They regulate protein-coding gene expression by mediating mRNA degradation and/or repressing translation via the association with the 3M-bM-^@M-^Y untranslated region (3M-bM-^@M-^Y UTR) of the mRNAs. Aberrant miRNA expression...

TranscriptomicsmiR148b is a major coordinator of breast cancer progression in a relapse-associated microRNA signature by targeting ITGA5, ROCK1, PIK3CA, NRAS and CSF1
Breast cancer is often fatal during its metastatic dissemination. To unravel the role of microRNAs (miRs) during malignancy, we analyzed miR expression in 77 primary breast carcinomas and identified 16 relapse-associated miRs that correlate with survival and/or distinguish tumor subtypes in differen...

TranscriptomicsmiR-148b modulates the expression of multiple genes
To identify which miR-148b targets were involved in tumorigenesis, a microarray analysis was performed for miR-148b over-expressing cells versus controls and 129 (49 up and 80 down) modulated genes were revealed. The effects of miR-148b on cancer progression depend on the direct and indirect regulat...
