Project description:This data set comprises population (46 samples) measurements of RNA expression levels for a subset of the 1000 Genomes Project CEPH samples. This data was generated as part of the following study: - Population Variation and Genetic Control of Modular Chromatin Architecture in Humans. Cell. 2015 Aug 27;162(5):1039-50. doi: 10.1016/j.cell.2015.08.001. Epub 2015 Aug 20. An additional set of 111 samples from the 1000 Genomes Project (GBR and TSI populations) were also assayed using RNA-seq. This data was generated as part of the following study: - Chromatin 3D interactions mediate genetic effects on regulatory networks.
Project description:This data set comprises population (47 samples) measurements of transcription factor DNA binding (PU.1 and RPB2) and histone modification (H3K27ac, H3K4me1 and H3k4me3) levels for a subset of the 1000 Genomes Project CEPH samples. This data was generated as part of the following study: - Population Variation and Genetic Control of Modular Chromatin Architecture in Humans. Cell. 2015 Aug 27;162(5):1039-50. doi: 10.1016/j.cell.2015.08.001. Epub 2015 Aug 20. An additional set of 111 samples from the 1000 Genomes Project (GBR and TSI populations) were also assayed for three histone modifications (H3K27ac, H3K4me1 and H3k4me3). This data was generated as part of the following study: - Chromatin 3D interactions mediate genetic effects on regulatory networks.
Project description:Global transcriptome analysis revealed altered expression of 291 genes, including mRNAs for several AR-interacting proteins and multiple enzymes involved in steroid metabolism. The data indicate that antiandrogens modify the androgen signaling in VCaP xenografts at multiple levels by reducing concentrations of active androgens, increasing AR expression and inducing alterations in the expression of AR interacting proteins, steroid metabolizing enzymes and AR downstream target genes.
Project description:We find that the 'high-confidence oscillating' genes initiate oscillations similarly as after release from L1 dauer. We performed high-throughput RNA sequencing on worms that were synchronously released from the dauer stage by refeeding on OP50. In particular, we investigate oscillatory gene expression as described in Hendriks et al., 2014 (doi: 10.1016/j.molcel.2013.12.013) and observe the re-initiation of oscillatory gene expression from stable expression with a time delay upon dauer exit. Experimental observation of the transitions between non-oscillatory and oscillatory states during the first 5 hours after dauer exit reveals that the oscillatory gene expression is arrested in a specific oscillator phase, similar to the observation we make in animals released from L1 arrest (see Meeuse et al., 2020, doi: https://doi.org/10.1101/755421).
Project description:Orthotopic tumors were previously generated from parental Prostate Luminal (PLum) cells under androgen‑dependent (PLum-AD) and androgen‑independent (PLum-AI) conditions in order to establish cellular models of prostate cancer progression (Abou-Kheir et al., 2011; doi: 10.1371/journal.pone.0026112). We used microarrays to evaluate the differential gene expression profiles underlying progression of prostate cancer from primary androgen-dependent stage to advanced androgen-independent stage using newly isolated murine prostate cancer cell lines. Those cell lines represent novel in vitro models of androgen‑dependent and –independent prostate cancer, recapitulating the progression of the disease to a more invasive phenotype upon androgen deprivation.
Project description:Transcriptional profiling of mouse whole liver comparing control WT B6 mice with B6 growth hormone-deficient little, B6 androgen receptor-null Tfm mice, and STAT5b KOs normalized to WT on B6 and BALB/c backgrounds. All animals were 10-week-old males initiated with DEN. Oberley et al. Molecular carcinogenesis 2014 May 17. doi: 10.1002/mc.22165.
Project description:Gene expression in VCaP prostate cancer cells treated with or without androgen was analyzed. VCaP cells containing a dox-inducible shRNA against Dtx3L were compared with and without dox induction (Dtx3L knockdown), in the presence or absence of androgen.
Project description:To examine the cellular heterogeneity in the PF, in mouse, we used droplet-based single cell RNA sequencing technique developed by Klein et al. 2015, Cell 161, 1187–1201. doi:10.1016/j.cell.2015.04.044.
Project description:Human tumor-associated macrophages (TAMs) were isolated from lung adenocarcinoma tissues and compared with alveolar macrophages (AMs) obtained from adjacent non-tumor tissues. For details, see Hoppstädter et al., 2021 (doi:10.1016/j.ebiom.2021.103578).
