Altered BAF53A (ACTL6A) Stoichiometry Drives Human Squamous Cell Carcinoma [RNA-seq]

ABSTRACT: To identify genes regulated by BAF53A, we carried out RNA-seq analysis in three SCC cell lines after BAF53A knockdown by siRNA and in normal keratinocytes with BAF53A overexpression.

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

Project description: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.

Increased ACTL6A occupancy within mSWI/SNF chromatin remodelers drives human squamous cell carcinoma.

Project description:Mammalian SWI/SNF (BAF) chromatin remodelers play dosage-sensitive roles in many human malignancies and neurologic disorders. The gene encoding the BAF subunit actin-like 6a (ACTL6A) is amplified early in the development of many squamous cell carcinomas (SCCs), but its oncogenic role remains unclear. Here we demonstrate that ACTL6A overexpression leads to its stoichiometric assembly into BAF complexes and drives their interaction and engagement with specific regulatory regions in the genome. In normal epithelial cells, ACTL6A was substoichiometric to other BAF subunits. However, increased ACTL6A levels by ectopic expression or in SCC cells led to near saturation of ACTL6A within BAF complexes. Increased ACTL6A occupancy enhanced polycomb opposition genome-wide to activate SCC genes and facilitated the co-dependent loading of BAF and TEAD-YAP complexes on chromatin. Both mechanisms appeared to be critical and function as a molecular AND gate for SCC initiation and maintenance, thereby explaining the specificity of the role of ACTL6A amplification in SCCs.

BAF53A drives colorectal cancer development by regulating DUSP5-mediated ERK phosphorylation.

Project description:BAF53A, an important subunit of the SWI/SNF epigenetic chromatin regulatory complex, has been implicated as the driver of diverse cancers. However, the role of BAF53A in colorectal cancer (CRC) remains poorly understood. Here, we examined the expression of BAF53A in CRC samples and observed that BAF53A was significantly upregulated in CRC tissues compared with paired adjacent normal tissues. In vitro and in vivo studies suggested that ectopic expression of BAF53A promoted colorectal cancer cell proliferation, colony formation, and tumorigenesis, whereas knockdown of BAF53A hindered these cellular functions. DUSP5 (dual-specificity phosphatase 5), an ERK1/2-specific endogenous phosphatase, was expressed at low levels in CRC. We found a negative correlation between BAF53A and DUSP5 expression in a set of CRC samples. Mechanistic studies revealed that P63 was a potential transcription repressor of DUSP5. BAF53A could interact with P63, decreasing the DUSP5 expression level and subsequently promoting ERK1/2 phosphorylation. Thus, our study provides insights into the applicability of the BAF53A-DUSP5-ERK1/2 axis as a potential therapeutic target in CRC.

Altered DNA Methylation Patterns in Human Oral Squamous Cell Carcinoma Cells

Project description:To gain insight into the DNA methylation changes during OSCC carcinogenesis, we utilized cytosine conversion and next generation sequencing based technique- enhanced reduced representation bisulfite sequencing (ERRBS) - to assess DNA methylation in cultured, human TERT-immortalized, non-tumorigenic OKF6-TERT1R and OSCC SCC-9 cells. OKF6-TERT1R cells and SCC-9 cells were plated in 10 cm2 tissue culture plates at the density of 2 M-CM-^W 106 cells/plate. Total genomic DNA was extracted from OKF6-TERT1R and SCC-9 cells using DNeasy Blood & Tissue Kit (Qiagen, Germantown, MD, USA), including an RNAse treatment step.
