Project description:Transcriptional profiling of 3D-retinas differentiated from mouse iPS cells comparing vehicle control- with 4-OHT-treated. 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 4-OHT-induced degeneration of photoreceptor cells in the 3D-retinas. 4-OHT-induced gene expression in the 3D-retinas was measured at DD 26 when the photoreceptor cells were degenerated. Two-condition experiment, vehicle control- vs. 5 µM 4-OHT-treated 3D-retinas. Biological replicates: each sample has 24 3D-retinas and 1 replicate.
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:MCF10A MycER cells were grown either on 2D monolayer culture in the presence of complete growth medium, in the absence of EGF and insulin or in 3D Matrigel culture for 20 days to form acinar structures. MycER was activated with 4-hydroxytamoxifen (4-OHT) in all samples for 2 or 48 h. Control cells were treated with ethanol. The aim of the study was to explore the effect of different growth conditions on gene expression changes in response to c-Myc activation.
