Integration of BRCA1-mediated miRNA and mRNA signatures reveal miR-146a, miR-99b and miR-205 regulation of the TRAF2 and NFkB pathways (miRNA dataset)

ABSTRACT: Microarray?based techniques are being used to obtain miRNA and gene expression signatures associated with different samples. In order to deepen our understanding of BRCA1-associated tumorigenesis, we integrated data from microarray experiments to obtain significant miRNA-mRNA relationships associated with the presence of the BRCA1 gene. We obtained significant miRNA-gene-pathway relationships underlying the array signatures. Furthermore, we have demonstrated that miR-146a, miR-99b and miR-205, induced in HCC1937 BRCA1-expressing cells, commonly regulate the TRAF2 gene, a key regulator of NF-?B and MAPK pathways. In addition, re-expression of miR-146a, miR-99b or miR-205 in HCC1937 BRCA1-null cells was sufficient to modulate NF-?B activity. Thus, integration between miRNA-mRNA expression da
