We used mammosphere formation assay and label-retention assay as functional cellular approaches to enrich for cells with different degree of cancer stem cell properties in the breast cancer cell line MDA-MB-231 and performed single-cell RNA sequencing Overall design: Single cells from three different populations: 30 cells from G1 cell cycle phase cultured in adherent conditions, 46 cells with low proliferation cultured in non-adherent conditions (mammosphere assasy), 45 cells with high proliferation cultured in non-adherent conditions (mammosphere assay)

View SamplesNeural stem/progenitor cells were isolated from the lateral ventricle wall of 4-6 week-old CD1 mice and grown as neurospheres under low density culture conditions. Test cells were transduced with bicistronic retroviral constructs for the over-expression of Bmi1 together with eGFP, and control cells were transduced with an empty vector construct expressing eGFP only. To identify genes, which are regulated by BMI1 in neural stem/progenitor cells, the gene expression profiles of neurosphere cells over-expressing Bmi1 were compared empty vector control cells using Affymetrix Gene mouse ST1.0 arrays
The putative tumor suppressor gene EphA7 is a novel BMI-1 target.

View SamplesTwo colon cancer cell lines are under study. SW480 and SW620. The first one is derived from primary cancer, SW620 are from lymphnode metastatic sites. they both comes from the sampe patient. Polisomal RNA fractions from the two isogenic colon cancer cells lines was purified by sucrose gradient and hybridized on affymetrix hgu133a chips. this study is complementary to the series GSE1323 were total RNA was used instead. Comparison between the polysomal fraction chips and the total RNA chips is performed and the analysis proposed in a paper from the authors (at the moment in preparation).

View SamplesSW480 and SW620 are colon cancer cells lines derived from a primary tumor and a corresponding metastasis from the same individual. The numbers indicate the three indipendent replicate RNA samples processed. Three different software packages were used in parallel for signal calculation: Affymetrix microarray suite 5.0, DNA-Chip analyzer, and Robust multi-array analyses.

View SamplesThe prime focus of the current therapeutic strategy for Multiple Myeloma (MM) is an early and deep tumour burden reduction; this characterizes and defines the complete response (CR). To date, no description of the characteristics of the plasma cells (PC) prone to achieve CR has been reported. This study aimed at the molecular characterization of PC derived from MM patients who achieved CR after bortezomib-thalidomide-dexamethasone (VTD) first line therapy.

View SamplesWe used microarrays to characterize the global changes in gene expression within the ascending aorta of mice due to conditional disruption of TGF- signaling in smooth muscle and/or due to heterozygous fibrillin-1 mutation.

View SamplesWe have used microarrays to identify individual genes and pathways regulated by Gq/11 or G12/13 signalling in type II alveolar epithelial cells isolated from the lungs of knockout mice.
Loss of epithelial Gq and G11 signaling inhibits TGFβ production but promotes IL-33-mediated macrophage polarization and emphysema.

View SamplesRecurrent chromosomal translocations involving the mixed lineage leukemia gene (MLL) give rise to highly aggressive acute leukemia associated with poor clinical outcomes. The preferential involvement of chromatin-associated factors in MLL rearrangements belies a dependency on transcriptional control. To identify new targets for therapeutic development in MLL, we performed a genome-scale CRISPR-Cas9 knockout screen in MLL-AF4 leukemia. Among validated targets, we identified the transcriptional regulator, ENL, as an unrecognized dependency particularly indispensable for proliferation. To explain the mechanistic role for ENL in leukemia pathogenesis and the dynamic role in transcription control, we pursued a chemical genetic strategy utilizing targeted protein degradation. ENL loss suppresses transcription initiation and elongation genome-wide, with pronounced effects at genes featuring disproportionate ENL load. Importantly, ENL-dependent leukemic growth was contingent upon an intact YEATS epigenomic reader domain. These findings reveal a novel dependency in acute leukemia and a first mechanistic rationale for disrupting YEATS domains in disease. Overall design: RNA-seq in MV4;11 (Cas9; ENL-FKBP(F36V); ENL -/-) cells with dTAG-13 and EPZ-5676 treatment
