Project description:Transcriptional profiling of 3D-retinas differentiated from mouse iPS cells comparing vehicle control with 4-OHT-treated w/o supplements. 4-OHT is an inverse agonist of estrogen-related receptor beta (ERRβ), a rod-enriched transcription factor responsible for maintenance of rod photoreceptor cells and the treatment induces photoreceptor specific cell death in the 3D-retinas. Goal was to understand the mechanism of protective effects of representative ophthalmic supplements for treating the photoreceptor degeneration. 4-OHT w/o supplements-induced gene expression in the 3D-retinas was measured at DD 25 when the photoreceptor cells started to be degenerated. Four-condition experiment, vehicle control- vs. 5 µM 4-OHT- vs. 5 µM 4-OHT with 400 µM vitamin E- vs. 5 µM 4-OHT with 200 nM lutein-treated 3D-retinas. Biological replicates: each sample has 24 3D-retinas and 1replicate.

Project description:RNA-seq: Gene expression profiling in MCF-7 cells treated with vehicle (0), estradiol (E2), the Selective ER Modulator 4-hydroxytamoxifen (OHT), or the pure antiestrogen fulvestrant (ICI). ChIP-seq: Genome-wide DNA binding profile of ERα and SUMO2/3 in MCF-7 cells treated with vehicle, E2 or ICI.
Project description:AE9aId1fl/flCreER cells treated with the control vehicle, CBD or 4-OHT We treated AE9aId1fl/flCreER leukemia with 0.1 μM 4-hydroxytamoxifen (4-OHT) for 48 hours or the Id1 inhibitor CBD (at 15 µM) for 16 hours, and isolated RNA for RNA-seq analysis.
Project description:Two induction systems, one based on the destablization domain (FKBP) and the other based on mutated ligand-binding domain of the estrogen receptor, require constant application of Shld1 and 4-hydroxytamoxifen (4OHT) to cells respectively, so we sought to quantify the extent to which these chemical inducers affect transcriptional networks. RW4 mouse ES cells were treated with Shld1 and 4-OHT respectively for 2 days and then subjected to gene expression profiling by microarray. Cells mock-treated with 95% ethanol as vehicle were used as controls. For each condition, two biological replicates were performed .
Project description:MCF7 breast cancer cell lines: drug-resistant (OHT and ICI) cell lines vs. drug-sensitive (wild type) cell lines. Assessment of association between gene expression and methylation. Two comparisons: OHT-resistant vs. wild type, and ICI-resistant vs. wild type. OHT: 4-hydroxytamoxifen ICI: fulvestrant ((ICI 182780) This submission represents the methylation component of the study.
