Baf155 establishes chromatin priming to promote hematopoietic regeneration and function [bulk ATAC]

Project description:Chromatin priming promotes cell type-specific gene expression, lineage differentiation, and development. The mechanism of chromatin priming has not been well understood. Mouse hematopoietic stem and progenitor cells (HSPCs) lacking the Baf155 subunit of the BAF (BRG1/BRM associated factor) chromatin-remodeler produced a significantly reduced number of mature blood cells, leading to a failure of hematopoietic regeneration upon transplantation and 5-FU injury. Baf155 deficient HSPCs, while showing impaired mature blood cell production, generated a higher frequency of myeloid cells with fewer B and CD8+ T cells at homeostasis, supporting a more immune-suppressive tumor microenvironment and enhanced tumor growth. Single-nuclei multi-omic analysis revealed that Baf155 deficient HSPCs failed to establish accessible chromatin and levels of lineage-specific transcripts were considerably lower. Regions that showed a substantial loss in chromatin accessibility were enriched for enhancers and binding motifs for hematopoietic lineage-specific transcription factors. Our study provides a fundamental mechanistic understanding of the role of Baf155 in establishing chromatin priming with functional consequences in regeneration or tumor immunity.

BAF155 methylation at R1064 creates unique chromatin association patterns

Project description:CARM1, a coactivator for various cancer-relevant transcription factors, is overexpressed in breast cancer. To elucidate the functions of CARM1 in tumorigenesis, we knocked out CARM1 from several breast cancer cell lines using Zinc-Finger Nuclease technology, which resulted in drastic phenotypic and biochemical changes. The CARM1 KO cell lines enabled identification of novel CARM1 substrates, notably the SWI/SNF core subunit BAF155. Methylation of BAF155 at R1064 was found to be an independent prognostic biomarker for cancer recurrence and to regulate breast cancer cell migration and metastasis. Further, CARM1-mediated BAF155 methylation affects gene expression by directing methylated BAF155 to unique chromatin regions (e.g., c-Myc pathway genes). Collectively our studies uncover a mechanism by which BAF155 acquires tumorigenic functions via arginine methylation. Examination of methylation of BAF155 (R1064) in breast cancer cells

Comparison of gene expression in skeletal muscle between Baf155 WT and mutant

Project description:Baf155 is a core subunit of SWI/SNF complex, an ATP dependent chromatin remodeler. To explore the function of Baf155 in skeletal muscle, we deleted the Baf155 in skeletal muscle and compared the gene expression profiling between wild type control and Baf155 deleted mutant mice.
