MetabolomicsIDH1 Reprograms Nucleotide Metabolism by Inducing Chromatin Remodeling and DHODH Transcription to Drive Chemoresistance in Nasopharyngeal Carcinoma

Metabolic reprogramming under therapeutic stress may represent a targetable vulnerability for cancer treatment. Elucidation of the metabolic alterations linked to chemotherapy in nasopharyngeal carcinoma (NPC) could uncover potential therapeutic strategies. Using proteomics and transcriptomic pro...

GenomicsMultiple Overlapping Mammalian Chromatin Remodeling Systems Collaborate Genome-wide at Dynamic Chromatin Transitions (ChIP-Seq)
ATP-dependent chromatin remodeling is an essential process required for the dynamic organization of chromatin structure. Here we describe the genome-wide location and activity of three remodeler proteins with diverse physiological functions in the mouse genome: Brg1, Chd4, and Snf2h. The localizatio...

TranscriptomicsDiet-induced chromatin remodeling in mice livers
The tissue-specific packaging of the genome into the nucleus through chromatin is fundamentally involved in gene regulation, and aberrant modifications to chromatin are a hallmark of many diseases. We show here that a high fat (HF) diet leads to substantial chromatin remodeling in the livers of C57B...

GenomicsHistone H2B ubiquitylation represses gametogenesis by opposing RSC-Dependent chromatin remodeling at the ste11 master regulator locus
Chromatin modifications play a pivotal role in cell fate decision. In fission yeast, the ste11 gene encodes the master regulator initiating the switch from vegetative growth to gametogenesis when cells starve. The methylation of H3K4 by Set1-COMPASS and consequent promoter nucleosome deacetylation w...

TranscriptomicsANGUSTIFOLIA 3 binds SWI/SNF chromatin remodeling complexes to regulate transcription during Arabidopsis leaf development
The transcriptional coactivator ANGUSTIFOLIA 3 (AN3) stimulates cell proliferation during Arabidopsis leaf development, but the molecular mechanism is largely unknown. We show here that inducible nuclear localization of AN3 during initial leaf growth results in differential expression of important t...

TranscriptomicsInvolvement of a chromatin remodeling complex in damage tolerance during DNA replication
ATP-dependent chromatin remodeling complexes have been shown to participate in DNA replication in addition to transcription and DNA repair. However, the mechanisms of their involvement in DNA replication remain unclear. Here, we reveal a specific function of the yeast INO80 chromatin remodeling comp...

TranscriptomicsCHD5, A Brain-Specific Chromatin Remodeling Enzyme, Regulates Expression Of Neuronal Genes.
CHD5 is frequently deleted in neuroblastoma, and appears to be a tumor suppressor gene; however, little is known about the role of CHD5. We found CHD5 mRNA was restricted to brain; by contrast most other remodeling ATPases were broadly expressed. CHD5 protein isolated from mouse brain was associat...

TranscriptomicsGenome-Wide Specificity of DNA-Binding, Gene Regulation, and Chromatin Remodeling by TALE- and CRISPR/Cas9-Based Transcription Factors
Synthetic DNA-binding proteins have found broad application in gene therapies and as tools for interrogating biology. Engineered proteins based on the CRISPR/Cas9 and TALE systems have been used to alter genomic DNA sequences, control transcription of endogenous genes, and modify epigenetic states. ...
