Disentangling the mutational effects on protein stability and interaction of human MLH1

In this study, the authors use high-throughput experimental approaches to test how missense mutations affect the cellular abundance of MLH1 and the interaction with its partner, PMS2. They find that many variants disrupting the interaction with PMS2 also lead to reduced cellular abundance levels, suggesting a strong relationship between protein stability and interaction in MLH1.

Mammary gland multi-omics data reveals new genetic insights into milk production traits in dairy cattle

Here, the authors focus on functional classes such as mammary-specific genes, lactation-associated genes, non-coding RNAs, RNA editing sites, DNA methylation and expression quantitative trait loci. Analyzing 3 million variants in 23,566 Holstein bulls, they identify key variants and functional classes that contribute significantly to genetic variation in milk production.

Exploring the molecular basis of the genetic correlation between body mass index and brain morphological traits

Here, the authors investigate the genetic variants that affect both obesity and brain morphology, identifying 21 genes whose expression affects both body mass index and morphological measures obtained from brain magnetic resonance imaging data. These results provide new insight into the complex relationships between the brain and obesity.

Genetic risk for neurodegenerative conditions is linked to disease-specific microglial pathways

In this study, the authors use a 3D genomic approach to map how genetic variants linked to neurodegenerative diseases interact with genes in different brain cell types. Their analysis reveals that genetic risk for Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, and amyotrophic lateral sclerosis is particularly enriched in microglia, the brain’s immune cells.

Conserved chromatin regulators control the transcriptional immune response to intracellular pathogens in Caenorhabditis elegans

In this study, the authors show that transcriptional regulators, previously linked to development in Caenorhabditis elegans, also control immune responses. They also discovered that other chromatin regulators similarly repress IPR gene expression, highlighting a new role in immunity for these conserved regulators of development.

Germline mutation rates and fine-scale recombination parameters in zebra finch

Here, the authors characterize properties of mutation and recombination in the zebra finch, which, like other birds, differs from mammals in several potentially salient respects, including its karyotype and the mechanism by which recombination is directed to the genome. By sequencing the genomes of three-generation pedigrees, the authors identify de novo mutations and recombination events.

YebC2 resolves ribosome stalling and increases fitness of cells lacking EF-P and the ABCF ATPase YfmR

The authors' work in this study suggests that EF-P, YfmR, and YebC2 act independently to prevent ribosome stalling and are important for maintaining cellular fitness.

Probing the limits of cis-acting gene regulation using a model of allelic imbalance quantitative trait loci

In this study, the authors show that in some tissues allelic imbalance is correlated with age; however, this correlation may be due to changes in the abundance of immune cell populations with age.

A phage-encoded counter-defense inhibits an NAD-degrading anti-phage defense system

Here, the authors determine how an anti-phage defense system encoded by an integrative and conjugative element recognizes phage infection to cause cell death prior to the generation of phage progeny.

Across PLOS

PLOS statement on recent US Executive Orders and scientific integrity

PLOS will always anchor our decisions in our values and our principles. And we will continue to speak up vocally for open, independent science.
A catalyst for better

We are on a mission to drive open science forward. We see the world through a lens of possibility, but we are not interested in change for the sake of change. We believe in better.

In 2025 and beyond, we will build on our catalytic legacy to effect positive change across all three of our focus areas.
PLOS Reviewer Center

A collection of free training and resources for peer reviewers of PLOS journals—and for the peer review community more broadly—drawn from research and interviews with staff editors, editorial board members, and experienced reviewers.
Submit your Lab and Study Protocols to PLOS ONE!

PLOS ONE is now accepting submissions of Lab Protocols, a peer-reviewed article collaboration with protocols.io, and Study Protocols, an article that credits the work done prior to producing and publishing results.
Integrating OpenAlex metadata to improve Open Science Indicators

Open Science Indicators (OSIs) are tools developed by us in collaboration with DataSeer to measure open science behaviors such as preprint posting, data-sharing, and code-sharing in a standardized way.
