The tomato Ty-6 gene conferring resistance against begomoviruses has been cloned and shown to be a variant of DNA polymerase delta subunit 1. Ty-6 is a major resistance gene of tomato that provides resistance against monopartite and bipartite begomoviruses. The locus was previously mapped on chromosome 10, and in this study, we fine-mapped Ty-6 to a region of 47 kb, including four annotated candidate genes.

Background: Cumulative risk scores predict negative outcomes including antisocial behaviour and mental health. Less work has examined the role of cumulative protection, despite the availability of preventive interventions focused on bolstering protection across domains. Understanding links between cumulative risk and protection measured in childhood and later outcomes can help to guide the timing of prevention programmes.

The effect of exercise and physical activity on skeletal muscle epigenetics and metabolic adaptations.

Eur J Appl Physiol

January 2025

Department of Kinesiology, Health Promotion, and Recreation, University of North Texas, Denton, TX, USA.

Physical activity (PA) and exercise elicit adaptations and physiological responses in skeletal muscle, which are advantageous for preserving health and minimizing chronic illnesses. The complicated atmosphere of the exercise response can be attributed to hereditary and environmental variables. The primary cause of these adaptations and physiological responses is the transcriptional reactions that follow exercise, whether endurance- (ET) or resistance- training (RT).

Development and validation of a molecular classifier of meningiomas.

Neuro Oncol

January 2025

MacFeeters Hamilton Neuro-Oncology Program, Princess Margaret Cancer Centre, University Health Network and University of Toronto, Toronto, ON, Canada.

Background: Meningiomas exhibit considerable clinical and biological heterogeneity. We previously identified four distinct molecular groups (immunogenic, NF2-wildtype, hypermetabolic, proliferative) that address much of this heterogeneity. Despite the utility of these groups, the stochasticity of clustering methods and the use of multi-omics data for discovery limits the potential for classifying prospective cases.

FGFR2 directs inhibition of WNT signaling to regulate anterior fontanelle closure during skull development.

Development

January 2025

Center for Craniofacial Molecular Biology, Department of Biomedical Sciences, Ostrow School of Dentistry, University of Southern California, Los Angeles, CA, 90033, USA.

The calvarial bones of the infant skull are linked by transient fibrous joints known as sutures and fontanelles, which are essential for skull compression during birth and expansion during postnatal brain growth. Genetic conditions caused by pathogenic variants in FGFR2, such as Apert, Pfeiffer, Crouzon syndromes, result in calvarial deformities due to premature suture fusion and a persistently open anterior fontanelle (AF). In this study we investigated how Fgfr2 regulates AF closure by leveraging mouse genetics and single-cell transcriptomics.

Purpose: To achieve a historical perspective, the chronological changes in primary liver cancer over a 20-year period were investigated at a single institution, focusing on shifts in etiology and the impact on imaging and pathological findings using The Liver Imaging Reporting and Data System.

Materials And Methods: A retrospective study of surgically resected primary liver cancer in 680 patients from 2001 to 2020 resulted in 434 patients with 482 nodules being analyzed. Dynamic contrast-enhanced computed tomography imaging and the Liver Imaging Reporting and Data System 2018 classification were employed.

Many animal species are known to show individuality in their acoustic communication. This variation in individual male signatures can be decisive for female choice. Within the damselfishes, Dascyllus species are known for prolific sound production during the realization of movements associated with courtship (i.

Background: Bioinformatics is fundamental to biomedical sciences, but its mastery presents a steep learning curve for bench biologists and clinicians. Learning to code while analyzing data is difficult. The curve may be flattened by separating these two aspects and providing intermediate steps for budding bioinformaticians.

Mutation impact on mRNA versus protein expression across human cancers.

Gigascience

January 2025

Department of Genetics and Genomic Sciences, Department of Artificial Intelligence and Human Health, Center for Transformative Disease Modeling, Tisch Cancer Institute, Icahn Genomics Institute, Icahn School of Medicine at Mount Sinai, New York, NY 10029, USA.

Background: Cancer mutations are often assumed to alter proteins, thus promoting tumorigenesis. However, how mutations affect protein expression-in addition to gene expression-has rarely been systematically investigated. This is significant as mRNA and protein levels frequently show only moderate correlation, driven by factors such as translation efficiency and protein degradation.

The rate at which mutations arise is a fundamental parameter of biology. Despite progress in measuring germline mutation rates across diverse taxa, such estimates are missing for much of Earth's biodiversity. Here, we present the first estimate of a germline mutation rate from the phylum Mollusca.

Data on Barrett's esophagus (BE) and esophageal cancer (EC) outcomes in patients with eosinophilic esophagitis (EoE) are limited. We aimed to determine the risk of prevalent BE (<1 year after endoscopy), incident BE (≥1 year after endoscopy), and incident EC in patients with versus without EoE, and to identify predictors of BE/EC in EoE patients. We identified adult patients in the Merative MarketScan Database who underwent first-time upper endoscopy between 2008 and 2020.

Spatiotemporal dynamics of fetal liver hematopoietic niches.

J Exp Med

February 2025

Immunology Department, Unit of Lymphocytes and Immunity, Institut Pasteur, Paris, France.

Embryonic hematopoietic cells develop in the fetal liver (FL), surrounded by diverse non-hematopoietic stromal cells. However, the spatial organization and cytokine production patterns of the stroma during FL development remain poorly understood. Here, we characterized and mapped the hematopoietic and stromal cell populations at early (E12.

The embryonic environment is critical for the development of many ectothermic vertebrates, which makes them highly vulnerable to environmental change. Changes in temperature and moisture, in particular, are known to influence embryo survival and offspring phenotypes. While most papers concerning phenotypic development of terrestrial ectotherms focus on the role of temperature on eggs and embryos, the comparatively small number of studies on the effects of substrate moisture are well suited for quantitative analysis aimed at guiding future research.

Attention-deficit hyperactivity disorder (ADHD) is a neurobiological condition that affects both children and adults. Microstate (MS) analyses, a data-driven approach that identifies stable patterns in EEG signals, offer valuable insights into the neurophysiological characteristics of ADHD. This review summarizes findings from 13 studies that applied MS analyses to resting-state and task-based brain activity in individuals with ADHD.

This study aimed to analyze the effect of different intervention strategies in physical education classes on the reduction of sedentary time. This is a randomized, school-based intervention with factorial characteristics, carried out with freshmen high school students from 11 full-time schools, allocated in three intervention situations: (A) schools with two extra physical education classes per week; (B) schools with training and engagement actions for physical education teachers; (C) Schools with both A and B strategies; and (D) a group of control schools. Accelerometry was used to obtain the effect measure of the main outcome (sedentary behavior).

Anticipatory Violence and Health Among Black Adults in the United States.

J Racial Ethn Health Disparities

January 2025

New Jersey Gun Violence Research Center, Rutgers University, Piscataway, NJ, USA.

This study analyzes the relationship between anticipatory community and police violence and health outcomes including mental and physical well-being, sleep problems, and functional disability. Using data from a nationally representative survey of 3015 self-identified Black and African American adults in the USA collected in 2023, findings from a series of regression analyses reveal that anticipating community violence is linked to poorer self-rated health and increased sleep problems. Anticipatory police violence is associated with poorer physical health and sleep disturbances.
