(Submitter supplied) The Facilitates Chromatin Transcription (FACT) is involved in chromatin remodeling during transcription, replication and DNA repair and is considered to be an ubiquitously expressed complex that has no known associations with any disease. However, we discovered that FACT is expressed in very limited number of cells of adult mammalian organism, mostly presented by stem and undifferentiated cells. Here, we show that FACT is present in poorly differentiated aggressive cancers with an overall low survival rate. more...

(Submitter supplied) Histone chaperone FACT is commonly expressed and essential for the viability of transformed but not normal cells and its expression levels correlate with poor prognosis in cancer patients. FACT binds several components of nucleosomes and has been viewed as a factor destabilizing nucleosomes to facilitate RNA polymerase passage. To connect FACT’s role in transcription with the viability of tumor cells, we analyzed genome-wide FACT binding to chromatin in conjunction with transcription in mouse and human cells with different degrees of FACT dependence. more...

(Submitter supplied) Small molecule curaxin CBL0137 has broad anti-cancer activity in different preclinical models. It interferes with histone-DNA interactions via binding to DNA without causing DNA damage. It resposents first in class "chromatin damaging" agent without genotoxic properties. Its effect on the transcription in human tumor cells was evaluated. DNA-targeting small molecules are widely used for anticancer therapy based on their ability to induce cell death, presumably via DNA damage. more...

(Submitter supplied) Small molecules directly binding DNA in cells destabilized chromatin what is "sensed" by histone chaperone FACT. FACT binds regions with destabilized chromatin via "c-trapping". DNA-targeting small molecules are widely used for anticancer therapy based on their ability to induce cell death, presumably via DNA damage. DNA in the eukaryotic cell is packed into chromatin, a highly-ordered complex of DNA, histones, and non-histone proteins. more...

(Submitter supplied) Diffuse intrinsic pontine glioma (DIPG) is an aggressive and incurable childhood brain tumor for which new treatments are needed. A high throughput drug screen of 3600 pharmaceutical compounds found that anti-malarials, including quinacrine had potent activity against DIPG neurospheres. CBL0137 is a novel anti-cancer compound developed from quinacrine, which targets Facilitates Chromatin Transcription (FACT), a chromatin remodelling complex involved in transcription, replication, and DNA repair. more...

(Submitter supplied) To assess the mechanisms by which FACT depletion leads to increased sensitivity of cells to be reprogrammed, we measured the chromatin accessibility landscape using ATAC-seq following mock treatment, SSRP1 knockdown, or SUPT16H knockdown in human fibroblasts and mock, hmg-3 or hmg-4 knockdown in whole worms, and differential gene expression in hmg-3 knockout mutants or following mock, hmg-4, or spt-16 knockdown by RNAseq.

(Submitter supplied) The conserved FACT (FAcilitates Chromatin Transcription) complex is a chromatin-reorganizing complex that promotes RNAPII transcription through chromatin templates by interacting with histones. It facilitates promoter activation by nucleosome eviction, and transcription elongation by nucleosome disruption and reassembly ahead and behind the RNAP. It also has a role in replication not fully understood yet. more...

(Submitter supplied) Transcription is a major obstacle for replication fork progression and transcription-replication collisions constitute a main cause of genome instability. At a genome-wide scale these obstacles can be detected by the accumulation of the replicative Rrm3 helicase required for RF progression through protein obstacles. Here we show that FACT, a chromatin-reorganizing complex that swaps nucleosomes around the RNA polymerase during transcription elongation and that also has a role in replication, is needed to resolve transcription-replication conflicts in Saccharomyces cerevisiae. more...

(Submitter supplied) Histone chaperones prevent promiscuous histone interactions before chromatin assembly. They guarantee faithful deposition of canonical histones and functionally specialized histone variants into chromatin in a spatial- and temporally-restricted manner. Here, we identify the binding partners of the primate-specific and H3.3-related histone variant H3.Y using several quantitative mass spectrometry approaches, and biochemical and cell biological assays. more...

(Submitter supplied) Preservation of nucleosomes during replication has been extensively studied, while the maintenance of nucleosomes during transcription has gotten less attention. The histone chaperone FACT is involved in transcription elongation, although whether it disassembles or assembles nucleosomes during the passage of RNA polymerase is still unclear. We deleted the FACT subunit in adult mice to clarify the function of FACT in mammals. more...

(Submitter supplied) Transcription factor access to regulatory elements is prevented by the nucleosome. Heat shock factor 1 (HSF1) is a winged helix transcription factor that plays roles in control and stressed conditions by gaining access to target elements, but mechanisms of HSF1 access have not been well known in mammalian cells. We show a physical interaction between the wing motif of human HSF1 and replication protein A (RPA), which is involved in DNA metabolism. more...

(Submitter supplied) The FACT complex and Spt6 are conserved histone chaperones that are recruited to the open reading frames of transcribed genes. In this study, we provide evidence that FACT interaction with acetylated H3 tail is important for its localization to the coding sequences. Pol II CTD kinase Kin28 additionally stimulates FACT recruitment to a subset of genes. Pol II occupancies in the 5’ ends of transcribed genes are greatly reduced on depleting FACT, whereas reduced occupancies at the 3’ ends were observed upon Spt6 depletion indicating that these factors modulate Pol II progression through distinct regions of transcribed coding sequences. more...

(Submitter supplied) Although the advances in genome-wide approaches have elucidated the functions of macrophage-specific distal regulatory elements in transcriptional responses, chromatin structures associated with PU.1 priming and the underlying mechanisms of action of these cis-acting sequences are not characterized. Here, we show that, in macrophages, FACT subunit SPT16 can bind to positioned nucleosomes directly flanking PU.1-bound sites at previously uncharacterized distal regulatory elements located near genes essential for macrophage development and functions. more...
