GenomicsGenome-wide profile of the SWI/SNF chromatin remodeling complex
A systems understanding of nuclear organization and events is critical for determining how cells divide, differentiate and respond to stimuli and for identifying the causes of diseases. Chromatin remodeling complexes such as SWI/SNF have been implicated in a wide variety of cellular processes includ...

TranscriptomicsANGUSTIFOLIA 3 binds SWI/SNF chromatin remodeling complexes to regulate transcription during Arabidopsis leaf development
The transcriptional coactivator ANGUSTIFOLIA 3 (AN3) stimulates cell proliferation during Arabidopsis leaf development, but the molecular mechanism is largely unknown. We show here that inducible nuclear localization of AN3 during initial leaf growth results in differential expression of important t...

ProteomicsThe nuclear granule Paraspeckles interacts with the chromatin remodeling SWI/SNF complex to regulate alternative splicing
Protein samples were analyzed by Multidimensional Protein Identification Technology (MudPIT), as described previously. Briefly, precipitated proteins were resuspended in 30uL of 100mM Tris pH 8.5 with 8M urea to denature proteins. Cysteines were reduced and alkylated prior to digestion with recombi...

ProteomicsRole of Specialized Composition of SWI/SNF Complexes in Prostate Cancer Lineage Plasticity
Advanced prostate cancer initially responds to hormonal treatment, but ultimately becomes resistant and requires more potent therapies. One mechanism of resistance seen in 10% of these patients is through lineage plasticity, which manifests in a partial or complete small cell or neuroendocrine pros...

ProteomicsExploring the interaction between the SWI/SNF chromatin remodeling complex and the zinc finger factor CTCF
The transcription factor CCCTC-binding factor (CTCF) modulates pleiotropic functions mostly related to gene expression regulation. The role of CTCF in large scale genome organization is also well established. A unifying model to explain relationships between many CTCF-mediated activities involve dir...

TranscriptomicsSWI/SNF Chromatin-Remodeling Factor Smarcd3/Baf60c Controls Epithelial-Mesenchymal Transition by Inducing Wnt5a Signaling
We previously identified a gene signature predicted to regulate the epithelial-mesenchymal transition (EMT) in both epithelial tissue stem cells and breast cancer cells. A phenotypic RNA interference (RNAi) screen identified the genes within this 140-gene signature that promoted the conversion of me...

ProteomicsSMARCB1 missense mutants disrupt SWI/SNF complex stability and remodeling activity
Chromatin remodeling complexes, such as the SWItch/Sucrose Non-Fermentable (SWI/SNF) complex, play key roles in regulating gene expression by modulating nucleosome positioning. The core subunit SMARCB1 is essential for these functions, as it anchors the complex to the nucleosome acidic patch, enabli...

ProteomicsOrganization, genomic targeting and assembly of three distinct SWI/SNF chromatin remodeling complexes in Arabidopsis
To comprehensively define the potential plant SWI/SNF sub-complexes and their subunits organization, we started by performing immuno-purification followed by mass spectrometry analysis (IP-MS) using stable transgenic Arabidopsis lines that expressed a green fluorescent protein (GFP)-tagged ATPase su...

TranscriptomicsRole of SWI/SNF in acute leukemia maintenance and enhancer-mediated Myc regulation [array]
Cancer cells frequently depend on chromatin regulatory activities to maintain a malignant phenotype. Here, we show that leukemia cells require the mammalian SWI/SNF chromatin remodeling complex for their survival and aberrant self-renewal potential. While Brg1, an ATPase subunit of SWI/SNF, is known...

TranscriptomicsIL-10 transcription is negatively regulated by BAF180, a component of the SWI/SNF chromatin remodeling enzyme
Several versions of SWI/SNF complexes, BAF and PBAF, have been described based on unique subunit composition. We find that T cell development in the thymus and lymphoid periphery is largely normal in the absence of the PBAF-specific component BAF180. However, BAF180-deficient Th2 cells express high...
