A barcode screen for epigenetic regulators reveals a role for the NuB4/HAT-B histone acetyltransferase complex in histone turnover. [PDF]

PLoS Genetics, 2011
Dynamic modification of histone proteins plays a key role in regulating gene expression. However, histones themselves can also be dynamic, which potentially affects the stability of histone modifications.

Histone Mutants Separate R Loop Formation from Genome Instability Induction [PDF]

, 2017
R loops have positive physiological roles, but they can also be deleterious by causing genome instability, and the mechanisms for this are unknown. Here we identified yeast histone H3 and H4 mutations that facilitate R loops but do not cause instability.

Histone modification in Drosophila [PDF]

Briefings in Functional Genomics, 2012
Post-translational modifications (PTMs) of nucleosomal core histones play roles in basic biological processes via altering chromatin structure and creating target sites for proteins acting on chromatin. Several features make Drosophila a uniquely effective model for studying PTMs.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Histone Deubiquitination Assay in Nicotiana benthamiana

Bio-Protocol, 2018
Histone modifications are a group of post-translational modifications on histones which can alter chromatin structure and affect gene expression. Histone ubiquitination is a histone modification found in particular on histone H2A and H2B.

Tumor mutational burden as a determinant of metastatic dissemination patterns

Molecular Oncology, EarlyView.
This study performed a comprehensive analysis of genomic data to elucidate whether metastasis in certain organs share genetic characteristics regardless of cancer type. No robust mutational patterns were identified across different metastatic locations and cancer types.

Involvement of histone modification in regulating CUP-SHAPED COTYLEDON genes during shoot regeneration in Arabidopsis

Biologia Plantarum, 2017
Histone modification is a ubiquitous regulator of gene transcription. Arabidopsis CUP-SHAPED COTYLEDON (CUC) genes serve as a marker for shoot apical meristem initiation, but how they are regulated during shoot regeneration from in vitro culture, it is ...

Interactions between core histone marks and DNA methyltransferases predict DNA methylation patterns observed in human cells and tissues

Epigenetics, 2020
DNA methylation and histone modifications are two major epigenetic marks in mammalian cells. Previous studies have revealed that these two mechanisms interact although a quantitative model of these is still lacking in mammalian cells.

Predicting gene expression in the human malaria parasite Plasmodium falciparum using histone modification, nucleosome positioning, and 3D localization features. [PDF]

, 2019
Empirical evidence suggests that the malaria parasite Plasmodium falciparum employs a broad range of mechanisms to regulate gene transcription throughout the organism's complex life cycle.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...
