TranscriptomicsmiRNA-cardiocirculatory
The short length of miRNAs results in a high dynamic range of melting temperatures and therefore impedes a proper selection of detection probes or optimized PCR primers. While miRNA microarrays allow for massive parallel and accurate relative measurement of all known miRNAs, they have so far been le...

TranscriptomicsReconstruction of microRNA/genes transcriptional regulatory networks of multiple myeloma through in silico integrative genomics analysis [PCL, miRNA]
The identification of deregulated miRNA in multiple myeloma (MM) has progressively added a further level of complexity to MM biology. In the present study, we take virtue of in silico integrative genomics analysis to generate an unprecedented global view of the transcriptional regulatory networks mo...

TranscriptomicsHigh IGFBP2 Expression Correlates with Tumor Severity in Pediatric Rhabdomyosarcoma.
Rhabdomyosarcoma (RMS) is the most common childhood sarcoma and is identified as either the embryonal or alveolar (ARMS) subtype. In approximately 75% of cases, ARMSs are characterized by specific chromosomal translocations that involve PAX and FKHR genes. ARMS gene expression signatures vary, depen...

TranscriptomicsTranscriptional analysis of genes regulating the mitochondrial dNTP pool in muscle cells.
Mutations in genes involved in dNTP metabolism can lead to tissue-specific mitochondrial depletion syndromes (MDS), likely because the expression of key enzymes is reduced to critical levels in post mitotic cells. Our goal was to establish an in vitro skeletal muscle cell model to study the muscle s...

TranscriptomicsGene expression profiling of miR27a over-expressing RH36 cell lines.
In order to identify direct or indirect miR-27a modulated genes, RH36 cells transfected with miR-27a precursors (pre-miR-27a or pre-control), analyzed 48h post-transfection, were used to perform microarray analysis. Gene expression profiling was carried out in ERMS cell line (RH36) transfected with...

TranscriptomicsTranscriptional profiling of ovarian cancer samples with different grades
We have previously demonstrated (Calura E et al., 2013) that different epithelial ovarian cancer (EOC) histotypes have different, defined characteristics at the microRNA level, which might highlight a different originating tissue for the disease. From these results we have invesigated whole-genome g...

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...

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...
