Myc influences global chromatin structure.
The family of myc proto-oncogenes encodes transcription factors (c-, N-, and L-Myc) that regulate cell growth and proliferation and are involved in the etiology of diverse cancers. Myc proteins are thought to function by binding and regulating specific target genes. Here we report that Myc proteins are required for the widespread maintenance of active chromatin. Disruption of N-myc in neuronal ...
متن کاملAnalysis of Myc-Induced Histone Modifications on Target Chromatin
The c-myc proto-oncogene is induced by mitogens and is a central regulator of cell growth and differentiation. The c-myc product, Myc, is a transcription factor that binds a multitude of genomic sites, estimated to be over 10-15% of all promoter regions. Target promoters generally pre-exist in an active or poised chromatin state that is further modified by Myc, contributing to fine transcriptio...
متن کاملAn active chromatin structure acquired by translocated c-myc genes.
We used general sensitivity to DNase I digestion to analyze the chromatin structure of c-myc genes in seven murine plasmacytomas. In every case, the 3' portion of c-myc juxtaposed with C alpha displayed a much more DNase I-sensitive chromatin structure than untranslocated c-myc or, in one case analyzed, the reciprocally translocated 5' portion. Our data suggest the presence of regulatory sequen...
متن کاملComparison of the Initial Treatment Results of N-myc Positive and N-myc Negative Neuroblastoma Patients
Background: Neuroblastoma is the most common extra cranial malignant solid tumor of childhood. Various molecular and cytogenetic factors have been implicated in the pathogenesis of neuroblastoma, some of which have proven useful in predicting clinical behavior. Over expression of the oncogen N-myc, is an important indicator of prognosis. Materials and Methods: Our study was performed from 20...
متن کاملTranscriptome regulation and chromatin occupancy by E2F3 and MYC in mice
E2F3 and MYC are transcription factors that control cellular proliferation. To study their mechanism of action in the context of a regenerating tissue, we isolated both proliferating (crypts) and non-dividing (villi) cells from wild-type and Rb depleted small intestines of mice and performed ChIP-exo-seq (chromatin immunoprecipitation combined with lambda exonuclease digestion followed by high-...
