Description
Carrying out both RNA-seq and Smad1/5 genome-wide chromatin immunoprecipitation and sequencing (ChIP-seq) analyses of mESCs in the naïve or primed states, we revisit the roles of BMP signaling in mESCs. Overall design: RNA-seq analysis in 2 cell types; mESCs and ES-derived EpiSC (ESD-EpiSCs).

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Dusp5 regulates ERK phosporylation following IL-33 receptor ligation in cultured eosinophils. Dusp5 deficient eosinophils show increased ERK phosphorylation, and as a result are less apoptotic. Since ERK stimulation results in downstream activation of transcription factors, we are utilizing a microarray approach to find alterations in gene expression to uncover potential mechanisms for increased cell survival.
Publication Title
Dusp5 negatively regulates IL-33-mediated eosinophil survival and function.

Description
Several different mechanical signals have been proposed to control the extent and pattern of myocardial growth and remodeling, though this has largely been studied using in vitro model systems that are not representative of intact myocardium or in vivo models in which isolating the effects of individual candidate stimuli is exceedigly difficult. We used a unique tissue culture system that allows the simultaneous control of multiple mechanical inputs and other potentially confounding stimuli (e.g., hormonal).

- Illumina HumanHT-12 V3.0 expression beadchip
Description
Estrogen Receptor-a (ER) is the key feature in the majority of breast cancers and ER binding to the genome correlates with the Forkhead protein FOXA1 (HNF3a), but mechanistic insight is lacking. We now show that FOXA1 is the defining factor that governs differential ER-chromatin interactions. We show that almost all ER-chromatin interactions and gene expression changes are dependent on the presence of FOXA1 and that FOXA1 dictates genome-wide chromatin accessibility. Furthermore, we show that CTCF is an upstream negative regulator of FOXA1-chromatin interactions. In ER responsive breast cancer cells, the dependency on FOXA1 for tamoxifen-ER activity is absolute and in tamoxifen resistant cells, ER binding occurs independently of ligand, but in a FOXA1 dependent manner. Importantly, expression of FOXA1 in non-breast cancer cells is sufficient to alter ER binding and response to endocrine treatment. As such, FOXA1 is the primary determinant that regulates estrogen-ER activity and endocrine response in breast cancer cells and is sufficient to program ER functionality in non-breast cancer contexts.
