Consensus Formation and Change are Enhanced by Neutrality

Advanced Science, EarlyView.
Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Exploring the Link between Nucleosome Occupancy and DNA Methylation

Frontiers in Genetics, 2018
Near promoters, both nucleosomes and CpG sites form characteristic spatial patterns. Previously, nucleosome depleted regions were observed upstream of transcription start sites and nucleosome occupancy was reported to correlate both with CpG density and ...

Nucleosome free regions in yeast promoters result from competitive binding of transcription factors that interact with chromatin modifiers. [PDF]

PLoS Computational Biology, 2013
Because DNA packaging in nucleosomes modulates its accessibility to transcription factors (TFs), unraveling the causal determinants of nucleosome positioning is of great importance to understanding gene regulation.

Nucleosomes and Cisplatin

Chemistry & Biology, 2010
In order to form a covalent complex with DNA inside human cells, cisplatin has to overcome the protective environment of a nucleosome, where DNA is complexed with histone proteins. Todd and Lippard (2010) expand our understanding of this process by describing the structure of a nucleosome containing a Pt-DNA adduct, which has important implications for

Embedded CRISPRi Enhances Gene‐Silencing Efficiency in Drosophila

Advanced Science, Volume 13, Issue 31, 4 June 2026.
Current CRISPR interference (CRISPRi) technology in Drosophila has limited efficiency. This study introduces the emCRISPRi platform, which significantly enhances transcriptional silencing efficacy by embedding inhibitory domains within the dCas9 architecture.

Nucleosome footprinting in plasma cell-free DNA for the pre-surgical diagnosis of ovarian cancer

npj Genomic Medicine, 2022
Fragmentation patterns of plasma cell-free DNA (cfDNA) are known to reflect nucleosome positions of cell types contributing to cfDNA. Based on cfDNA fragmentation patterns, the deviation in nucleosome footprints was quantified between diagnosed ovarian ...

A Functionally Conserved Enhancer is Critical for PGC1A Expression and Thermogenesis in Brown Fat

Advanced Science, Volume 13, Issue 31, 4 June 2026.
An evolutionarily conserved enhancer controls PGC1A expression and thermogenic activation in brown adipose tissue. Integrative multi‐omics analyses identify two BAT‐specific enhancers, with PGC1A‐En1 functioning as the dominant regulatory element that maintains thermogenic capacity across species.

Hijacking the Host Clock: A Nematode Effector Antagonizes Soybean Circadian Defense and Translation Control

Advanced Science, EarlyView.
Soybean employs its circadian clock, governed by GmCCA1, to rhythmically defend against soybean cyst nematodes. The pathogen retaliates by secreting the effector Hg4E02, which hijacks the clock to suppress defense and co‐opt the host's translation machinery for nutrient acquisition.
