Transcriptomicsp53-repressed miRNAs are Involved with E2F in a Feed Forward Loop Promoting Proliferation
Analysis of miRNA expression in human breast cancer samples with Agilent's miRNA arrays. These samples are part of a study where we have investigated the mammalian cell proliferation control network consisting of transcription regulators, E2F and p53, their targets, and a family of 14 microRNAs. We ...

Transcriptomicsp53-repressed miRNAs are Involved with E2F in a Feed Forward Loop Promoting Proliferation
miRNA expression profiles of WI38 primary human fibroblasts with an active or inactive p53. Cells were compared under normal untreated conditions (young and proliferating cells), after DNA damage with Doxorubicin, and upon entry into replicative senescence. Keywords: miRNA, WI-38, p53, GSE56, Senes...

TranscriptomicsThe effect of miRNA overexpression on gene expression profile of MCF-7 cells
To identify microRNAs impacting estrogen receptor ERα expression in breast cancer, we have screened ER-positive breast cancer cells with a library of pre-miRs, and systematically monitored the ERα expression by protein lysate microarrays. There was a significant enrichment of the in silico predict...

TranscriptomicsMolecular Characterization of Breast Cancer Subtypes from Joint Analysis of High Throughput miRNA and mRNA Data (II)
MicroRNAs (miRNAs) are a class of short, single-stranded widely expressed noncoding RNAs that regulate the stability or translational efficiency of target messenger RNAs. Date derived from expression profiling of 489 miRNAs in 101 human primary breast tumor samples, along with genome-wide matched mR...
