Caspases are cysteine-proteases with key roles in the execution phase of apoptosis. Additional cellular activities, unrelated to cell death seem to be influenced by these enzymes. Identification of genes co-regulated with caspases could help to ascertain new biological roles for these proteases.To identify genes and pathways under the influence of caspase-2 we silenced its expression in U87MG glioblastoma cell line. Transcriptional expression profiles of cells transfected with caspase-2 siRNA or control siRNA were compared.

View SamplesPurpose: The goal was to capture the transcriptional activity due to over-expression of HER2 protein. We profiled this transcriptional activity using two different RNA-Seq alignment and quantification pipelines. We also used these samples to generate a gene expression signature of HER2 pathway activity. Over-expression was validated using Western blots. Illumina RNA-Seq technology was used to capture the downstream transcriptional activity. Reads were 101 base pairs long and single ended. An R open source package “Rsubread” was used to align and quantify the read using UCSC hg19 annotation. The integer-based gene counts were later normalized in FPKM and TPM . Overall design: A profile of gene expression, downstream of ERBB2/HER2 over-expression, was generated in cells derived from breast and used to generate a gene-expression signature reflective of HER2 pathway activation status.
Alternative preprocessing of RNA-Sequencing data in The Cancer Genome Atlas leads to improved analysis results.

View SamplesThe M1 and the M2 macrophage polarization programs (activated by IFN? and IL-4, respectively) lie at the opposite edges of a continuum of activation states but are frequently co-activated during co-infections and in cancer despite controlling divergent functional responses. Whether these two programs are mutually exclusive, how they influence each other, and whether one represents the prevailing response, are all open questions. Co-administration of IFN? and IL-4 exerted complex inhibitory effects over the M1 and M2 programs at the level of both epigenomic and transcriptional changes. Computational data mining and validation analyses revealed the molecular basis of the differential sensitivity of genes and cis-regulatory elements to the antagonistic effects of the opposite stimulus. For instance, while STAT1 and IRF motifs were associated with robust and IL-4-resistant responses to IFN?, their coexistence with binding sites for some auxiliary transcription factors such as AP-1, generated vulnerability to IL-4-mediated inhibition. These data provide a core mechanistic framework for the integration of signals that control macrophage activation and the starting point for understanding macrophage responses in complex environmental conditions Overall design: Analysis of transcriptional and epigenomic changes in mouse macrophages stimulated with different cytokines or their combinations
Opposing macrophage polarization programs show extensive epigenomic and transcriptional cross-talk.

View SamplesEGFR and MEK pathways were activated alone or in combination in human mammary epithelial cells. We profiled the pathway gene expression signatures using RNA-Seq. Overall design: mRNA was extracted from human mammary epithelial cells overexpressing EGFR gene, MEK gene, or EGFR and MEK genes in combination (or GFP control) for RNA-Seq analysis. Experiment was performed in six replicates per condition.

View SamplesEndometriosis is a complex pathological condition in which multiple components are involved in the disease development and clinical outcome. Endometriosis is mainly an inflammatory codition estrogen-dependent, with unknown pathogenesis, that is characterized by dissemination of edometrium tissue in ectopic position (ovary or pelvic peritoneum). Two main theories rise the pathologic onset: the presence of retrograde menstruation and celomic metaplasia in the pelvic peritoneum, that can occur for development defects. Endometriosis is related not only to genetic or immunological changes and to environmental pollution factors, as the endocrine interferents. The disease phenotype results from multiple events (genetics and enviromental), thus it is difficult to find a single gene as causative while is more probable that a gene network/s might involved in the onset and mantainement of the disease state. The peculiarity of endometriosis rely on the tissue speificity manteinance in the ectopic position, where it responds to the hormone stimuli as the tissue in the eutopic position.
Transcriptional profiling of endometriosis tissues identifies genes related to organogenesis defects.
