Bptf maintains chromatin accessibility and the self-renewal capacity of mammary gland stem cells [RNA-Seq]

Project description:Chromatin remodeling is a key requirement for transcriptional control of cellular differentiation. However, the factors that alter chromatin architecture in mammary stem cells (MaSCs) are poorly understood. Here we show that Bptf, the largest subunit of the NURF chromatin remodeling complex, is essential for MaSC self-renewal and differentiation of epithelial cells in the mammary gland. Bptf depletion arrests cells at a previously undefined stage of epithelial differentiation that is associated with an incapacity to achieve the luminal cell fate. Moreover, genome-wide analysis of DNA accessibility following genetic and chemical inhibition of Bptf, suggests a role for this factor in maintaining the open chromatin landscape of cis-regulatory elements in mammary epithelial cells (MECs). Collectively, our study implicates Bptf in maintaining the unique epigenetic state of MaSCs.

AR RIME in Human Prostate Cancer Cells

Project description:BPTF, the scaffolding subunit of the nucleosome remodeling factor (NURF) complex, has been implicated in the progression of several malignancies, but its role in prostate cancer (PCa) remains unclear. Here, we demonstrate that BPTF is upregulated in castration-resistant prostate cancer (CRPC) and promotes disease progression. RNA-seq revealed that BPTF primarily enhances the expression of androgen receptor (AR) target genes. ChIP-seq showed that BPTF increases AR binding at promoters, enhancers and super-enhancers. ATAC-seq further demonstrated that BPTF increases chromatin accessibility to facilitate AR binding, in part through SMARCA1, a catalytic subunit of the NURF complex. Notably, BPTF/AR co-bound regions are highly enriched for FOXA1 motifs but only weakly enriched for AR motifs. We further show that BPTF forms a protein complex with AR and FOXA1, in which FOXA1 recruits the BPTF-AR complex to chromatin, while BPTF stabilizes the AR-FOXA1 interaction. Importantly, BPTF interacts with AR through its bromodomain, and a BPTF bromodomain inhibitor disrupts this interaction, impairs AR signaling and suppresses PCa cell growth. In summary, our findings establish BPTF as a critical regulator of AR activity by promoting chromatin accessibility and stabilizing the AR-FOXA1 complex, highlighting BPTF as a potential therapeutic target in prostate cancer.

The chromatin remodeler Bptf activates a stemness gene-expression program essential for the maintenance of adult hematopoietic stem cells [ChIP-Seq]

Project description:Bptf, a component of NURF chromatin-remodeling complex, is essential for maintaining the pool size and function of hematopoietic stem cells (HSCs). Genome-wide transcriptome profiling revealed that Bptf loss caused down-regulation of HSC-specific gene-expression programs, which included master transcription factors (such as Meis1, Pbx1, and Lmo2) known to be required for HSC maintenance and self-renewal. Bptf directly bound to the promoter of ‘stemness’ TF genes, potentiating their transcription and DNA accessibility.
