WebAug 31, 2016 · Indeed, we found that DNA supercoiling at CTCF sites was: (1) lost after treatment with the RNA polymerase II inhibitor alpha-amanitin; (Fig. 7a); (2) is reduced … WebCCCTC-binding factor (CTCF) is a DNA-binding protein that interacts with a large number of highly divergent target sequences throughout the genome. It is implicated in a variety of functions, including chromatin organization and transcriptional control. The functional role of CTCF in tumour pathogenesis remains elusive.
Elevated enhancer-oncogene contacts and higher oncogene
WebOct 14, 2024 · Both HOX gene expression and CTCF regulation have been well demonstrated to play a critical role in regulating maintenance of leukemic stem cells (LSCs) that are known to be resistant to BET inhibitor (BETi). To investigate the regulatory role of CTCF boundary in aberrant HOX gene expression and the therapeutic sensitivity of BETi … WebT-ALL is characterized by specific driving oncogene rearrangements that delineate 4 to 5 subtypes that harbor unique expression signatures. 63, 69, 70, 71 CTCF aberrations were especially frequent in patients with T-ALL with TLX3-rearrangements (53%) compared with patients with other driving oncogenic rearrangements (6%, p = 2.2 × 10 −16; Figure 1 E). foam sections
Transcription Factor CTCF - an overview ScienceDirect Topics
WebIn SEM cells, CTCF and RAD21 show a strong positive correlation at ATAC peaks (Fig. 1b), suggesting that all or most of these CTCF binding sites are competent to enrich or stabilize RAD21 ... WebDec 20, 2024 · Among the latter, a relevant role is played by the insulator factor CCCTC-binding factor (CTCF), which is a direct target of covalent and non-covalent PARylation [38,44]. Moreover, CTCF interaction with the PARP-1 protein stimulates its enzymatic activity independently of DNA damage [42,45]. WebCohesin is a more potent inhibitor of KSHV transcription than CTCF but both proteins are also required for efficient transcription of a subset of KSHV genes. These data reveal novel effects of CTCF and cohesin on transcription from a relatively small genome that resemble their effects on the cellular genome by acting as gene-specific activators ... greenwood village colorado spectrum
