Transcriptionally Driven DNA Replication Program of the Human Parasite Leishmania major

Cell Reports, 2016
Faithful inheritance of eukaryotic genomes requires the orchestrated activation of multiple DNA replication origins (ORIs). Although origin firing is mechanistically conserved, how origins are specified and selected for activation varies across different

Stage‐Specific H3K14 and H3K23 Succinylation Orchestrates Insect Metamorphosis and Oogenesis

Advanced Science, EarlyView.
Stage‐specific succinylation of histone H3 at lysine 14 and 23 differentially controls insect metamorphosis and oogenesis through distinct GPCR‐PKC signaling cascades, revealing an evolutionarily conserved epigenetic mechanism that coordinates key life‐history traits.

Short Histone H2A Variants: Small in Stature but not in Function

Cells, 2020
The dynamic packaging of DNA into chromatin regulates all aspects of genome function by altering the accessibility of DNA and by providing docking pads to proteins that copy, repair and express the genome.

In Vitro Studies of Nucleosome Positioning and Stability at the PHO5 and PHO8 Promoters in Saccharomyces cerevisiae [PDF]

, 2006
The PHO5 and PHO8 genes in yeast provide typical examples for the role of chromatin in promoter regulation. Both genes are regulated by the same transcriptional activator, Pho4, which initiates nucleosome remodeling and transcriptional activation.

A Non‐Canonical Core Transcriptional Regulatory Circuit Orchestrates Chromatin Reprogramming to Drive Osimertinib Resistance in Non‐Small Cell Lung Cancer

Advanced Science, EarlyView.
A non‐canonical core transcriptional regulatory circuit, composed of ID3, SMAD3, and NR2F2, drives Osimertinib resistance in non‐small cell lung cancer through super‐enhancer‐mediated activation of EPAS1, which couples neuroendocrine differentiation with ferroptosis evasion.

Mechanism of chromatin reassembly at the yeast PHO5 promoter upon repression [PDF]

, 2007
The goal of this study has been to elucidate the mechanisms responsible for rebuilding nucleosomes at the PHO5 promoter upon rerepression. In this work, I could unambiguously show that histones are incorporated at the PHO5 promoter upon repression ...

Telomeric nucleosomes are intrinsically mobile

, 2007
Nucleosomes are no longer considered only static basic units that package eukaryotic DNA but they emerge as dynamic players in all chromosomal processes.

Pyrosequencing positions nucleosomes precisely [PDF]

, 2007
New parallel-sequencing technology has recently been used to map with unprecedented accuracy the positions of nucleosomes enriched for the histone variant H2A.Z throughout the yeast ...

Stem Cell Differentiation Disperses Transcriptional Clusters via a Conserved Surface‐Condensate Trajectory

Advanced Science, EarlyView.
Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...

Whole genome regulatory effect of MoISW2 and consequences for the evolution of the rice plant pathogenic fungus Magnaporthe oryzae

mBio
Isw2 proteins, ubiquitous across eukaryotes, exhibit a propensity for DNA binding and exert dynamic influences on local chromosome condensation in an ATP-dependent fashion, thereby modulating the accessibility of neighboring genes to transcriptional ...
