RNA-seq of doxycycline induced tumor and residual mouse primary mammary epithelial cells grown in 3D cell cultures against non-induced controls

ABSTRACT: This experiment investigates the expression characteristics of residual breast cancer cells. Primary mammary epithelial cells taken from female mice with doxycycline-inducible hMyc- and Neu/Her2-oncogenes were grown in 3D organoid cultures. Upon the addition of doxycycline (200ng/mL) to the medium the expression of the oncogenes gets activated and the cells start uncontrolled proliferation resembling tumor growth. Tumor samples were taken after 5 days of oncogene induction. Subsequently, doxycycline was removed from the medium, which silences oncogene expression and results in rapid tumor regression. Residual samples reminiscent to the non-induced (normal) structures were taken after 7 days of de-induction (12 days overall). Non-induced structures were grown and sampled in parallel.

Enzymatic Methyl-seq (EM-seq) of doxycycline induced tumor and residual mouse primary mammary epithelial cells grown in 3D cell cultures against non-induced controls

Project description:This experiment investigates the genome wide DNA methylation landscape of residual breast cancer cells. Primary mammary epithelial cells taken from female mice with doxycycline-inducible hMyc- and Neu/Her2-oncogenes were grown in 3D organoid cultures. Upon the addition of doxycycline (200ng/mL) to the medium the expression of the oncogenes gets activated and the cells start uncontrolled proliferation resembling tumor growth.

Single-cell RNAseq of whole mouse E8.25 embryos

Project description:Gastrulation represents a pivotal point in mammalian development, when the basic body plan is established and cells are specified into one of the three germ layers. This is followed by rapid diversification into specific lineages and the appearance of the various cell types required to build each of the organs. The rich variety of cell types present at this stage has never been rigorously characterised in any mammalian organism, and thus insight into cell fate decisions and the underlying regulatory networks have been inaccessible. We have used droplet based single-cell RNA-sequencing to address this by profiling ~7000 cells from three E8.25 mouse embryos.

RNA-seq of DCIS-pInducer21-SOX11 cells grown in 2D and 3D

Project description:Using the pINDUCER21 system, we modified DCIS.com cells so that SOX11 is expressed at much higher levels after induction with Doxycycline (Dox) than observed with the constitutive DCIS-SOX11 cells we have used to model DCIS progression. After Dox induction of pIND21-SOX11 cells, both SOX11 and CD24 expression are significantly increased ). Higher ALDH levels are detected in pIND21-SOX11 cells, suggesting that high levels of SOX11 promotes acquisition of features associated with distinct types of cancer stem cells.

Identification of a novel Bromodomain / Casein Kinase II / TAF-containing complex as a regulator of mitotic condensin function

Project description:ABSTRACT: Condensin is a central regulator of mitotic genome structure, with mutants showing poorly condensed chromosomes and profound segregation defects. Here we identify the fission yeast NCT complex, comprising the Nrc1 BET-family tandem bromodomain protein (SPAC631.02), Casein Kinase II (CKII) and several TAFs, as a novel regulator of condensin function (where NCT mutants restore the formation of segregation-competent chromosomes in cells containing defective condensin). Synchronous ChIP-seq shows that NCT and condensin bind similar genomic regions, but only briefly co-localize during the periods of chromosome condensation and decondensation. These results are consistent with a model where NCT targets CKII to chromatin in a cell cycle-directed manner to modulate the activity of condensin during chromosome condensation and decondensation. DATA: Study includes ChIP-seq of fission yeast H3-K4Me3, H3-K36Me3, TBP, Taf7, Nrc1, Cka1 from aynchronous cells; Nrc1 and Cut3 (representing condensin) from four synchronized cell-cycle stages estimated as G2/M, Metaphase, Anaphase and G1/S.

Global Run-On sequencing (GRO-seq) of HeLa cells under CDK9 inhibitor tratment to study elongation checkpoints at both ends of RNA polymerase II-transcribed genes.

Project description:Global Run-On sequencing (GRO-seq) was carried out on nuclei isolated from HeLa cells after 30 minutes of treatment with CDK9 inhibitors KM05382 and DRB and from two untreated controls. Libraries of nascent RNAs were generated and sequenced using Illumina Hi-seq technology. GRO-seq reads were processed, deduplicated, mapped to human genome and normalised to reads in the 5’ ETS of the 45S rRNA gene.

scRNA-seq time course of cerebellar Nestin-expressing progenitors from neonatal mice with and without injury at birth

Project description:To investigate the molecular changes that NEP subpopulations endure upon injury and to determine whether specific populations of NEPs have a transient increase in the signaling pathways associated with injury induced cellular stress and ROS, we performed multiplexed scRNA-seq of NEPs (CFP+) isolated by fluorescence activated cell sorting (FACS) from Nes-CFP/+ transgenic neonates with and without irradiation at timepoints P1, P2, P3 and P5.
