Recently, it was described that mammalian cells are able to eliminate those with relative lower Myc levels in the epiblast through cell competition. We have described that cardiomyocytes during heart development are also able to complete eliminating cells with lower Myc levels. We have also shown that adult cardiomyocytes respond in the same way over long periods of time when cell competition is induced by overexpressing Myc in a mosaic fashion. We therefore have developed an RNASeq assay to further understand the mechanism of elimination of WT cells and the effect of mild Myc overexpression in cardiomyocytes. Overall design: Myc overexpression in a mosaic fashion in adult cardiomyocytes, 2 hearts were analyzed and two wild type littermates were used as controls
Cell competition promotes phenotypically silent cardiomyocyte replacement in the mammalian heart.

View SamplesMantle cell lymphoma (MCL) is an aggressive B-cell neoplasm displaying heterogeneous outcomes after treatment. In 2003, the Lymphoma/Leukemia Molecular Profiling Project described a powerful biomarker, the "proliferation signature", using gene expression in fresh frozen material. Here we describe the training and validation of a new assay that measures the proliferation signature in RNA derived from routinely available formalin-fixed paraffin-embedded (FFPE) biopsies.

View SamplesBrown adipose tissue (BAT) thermogenesis and the browning of white adipose tissue are important components of energy expenditure. An RNAseq-based analysis of the mouse BAT transcriptome led us to identify GPR120 as a gene induced by thermogenic activation. GPR120, a G protein-coupled receptor binding unsaturated long-chain fatty acids, is known to mediate some beneficial metabolic actions of polyunsaturated fatty acids. We show that pharmacological activation of GPR120 induces BAT activity and promotes the browning of white fat in mice, whereas GRP120-null mice show impaired browning in response to cold. n-3 polyunsaturated fatty acids induce brown and beige adipocyte differentiation and thermogenic activation, and these effects require GPR120. GPR120 activation induces the release of fibroblast growth factor-21 (FGF-21) by brown and beige adipocytes and increases blood FGF21 levels. The effects of GPR120 activation are impaired in FGF21-null mice and cells. Thus, the lipid sensor GPR120 constitutes a novel pathway of brown fat activation and involves FGF21. Overall design: eight adult male C57BL6 mice were maintained at thermoneutral temperature (29C). After two weeks, a subset of four mice was placed at 4C environment temperature for 24h. RNAseq was performed on the BAT tissues of these 2 groups.

View SamplesThe neural transcription factor SOX11 is overexpressed in aggressive lymphoid neoplasms mainly in mantle cell lymphoma (MCL), but its functional role in malignant B-cells is unknown. To identify target genes transcriptionally regulated by SOX11 in malignant lymphoid cells, we have used Gene Expression Profiling (GEP) after SOX11 silencing in MCL cell lines.
SOX11 regulates PAX5 expression and blocks terminal B-cell differentiation in aggressive mantle cell lymphoma.

View SamplesMantle cell lymphoma (MCL) is an aggressive neoplasm with poor outcome. However, some patients have an indolent disease (iMCL) and may not require intensive treatment at initial diagnosis. Diagnostic criteria to recognize these patients are not available. We hypothesized that the analysis of the genetic and expression features of the tumors may help to identify patients with an indolent clinical evolution and provide biomarkers that could be used in the clinical setting.
