Altered BAF53A (ACTL6A) Stoichiometry Drives Human Squamous Cell Carcinoma [CnR]

ABSTRACT: To determine whether the chromatin accessibility for YAP/TEADs in squamous cell carcinoma cells is directly regulated by BAF53A within BAF complexes, we performed CUT&RUN to profile the distribution of YAP, TEAD1, and BAF155 (a DNA binding subunit of BAF complexes) across the genome.

Baf53a is involved in survival of mouse ES cells, which can be compensated by Baf53b.

Project description:The human Baf (Brg1/Brm associated factor) complex, also known as the mammalian SWI/SNF chromatin-remodeling complex, is involved in a variety of cellular processes. The pluripotency and self-renewal abilities are major characteristics of embryonic stem (ES) cells and are regulated by the ES cell-specific BAF (esBAF) complex. Baf53a is one of the subunits of the esBAF complex. Here, we found that growth of Baf53a-deficient ES cells was repressed, and expression of p53, p21, and cleaved Caspase 3 was increased. Interestingly, Baf53b, a homologue of Baf53a, rescued cell death of Baf53a-deficient ES cells. Baf53a-deficient ES cells overexpressing exogenous Baf53a or Baf53b remained in the undifferentiated state and proliferated. In summary, our findings suggest that Baf53a is involved in the survival of ES cells, and that Baf53b is able to compensate for this functional aspect of Baf53a.

The study of dpf2 in mouse ES cells

Project description:Brg-or Brm-associated factor (BAF) complexes, is a 12 subunit complex which contains an ATPase subunit, Brg or Brm, that uses energy derived from ATP hydrolysis to disrupt histone:DNA contacts to catalyze transcriptional events such as promoting gene expression or repression. Genetic studies in mice demonstrated that BAF complexes are essential for early embryonic development and pluripotency. ES cells express distinctive compleses, termed esBAF complexes by the presence of BAF155, Brg, BAF60a. Purification of Brg and Brm-associated proteins reveals a new family of four stoichiometric subunits of mSWI/SNF or BAF complexes which was termed BAF45a, b, c, and d. The progenitors to both neurons and glia are maintained in a proliferative state by a specified SWI/SNF-like npBAF complex that contains both BAF45a and BAF53a. The transition from proliferative to neurogenic divisions requires the exchange of these subunites for the homologous BAF45b or BAF45c and BAF53b proteins. The function of BAF45d remwains unclear so far.At present, we found that the knockout of dpf2 in ES cells impared the differention of ES cells. We will identify the target genes of dpf2 by Chip-seq so that we could study how dpf2 affect the differentiation of ES cells into germ layers.Protocol: DNA was prepared from ES cells by standard ChIP method.

BAF subunit switching regulates chromatin accessibility to control cell cycle exit in the developing mammalian cortex [ATAC-seq]

Project description:mSWI/SNF or BAF chromatin regulatory complexes are dosage-sensitive regulators of human neural development frequently mutated in autism and intellectual disability. Cell cycle exit and differentiation of neural stem/progenitor cells is accompanied by BAF subunit switching to generate neuron-specific nBAF complexes. We manipulated the timing of BAF subunit exchange in vivo and found that early loss of the npBAF subunit BAF53a stalls cell cycle exit to disrupt neurogenesis. Loss of BAF53a results in decreased chromatin accessibility at specific neural transcription factor binding sites, including the pioneer factors Sox2 and Ascl1, due to Polycomb accumulation. This results in repression of cell cycle genes, thereby blocking cell cycle progression and differentiation. Cell cycle block upon Baf53a deletion could be rescued by premature expression of the nBAF subunit BAF53b but not by other major drivers of proliferation or differentiation. Wnt, EGF, FGF, Sox2, myc or Pax6 all fail to maintain proliferation in the absence of BAF53a, highlighting a novel mechanism underlying neural progenitor cell cycle exit in the continued presence of extrinsic proliferative cues.
