Summary: Elemental imaging provides detailed profiling of metal bioaccumulation, offering more precision than bulk analysis by targeting specific tissue areas. However, accurately identifying comparable tissue regions from elemental maps is challenging, requiring the integration of hematoxylin and eosin (H&E) slides for effective comparison. Facilitating the streamlined co-registration of whole slide images (WSI) and elemental maps, TRACE enhances the analysis of tissue regions and elemental abundance in various pathological conditions.

Assessing Metabolic Ageing via DNA Methylation Surrogate Markers: A Multicohort Study in Britain, Ireland and the USA.

Aging Cell

January 2025

MRC Centre for Environment and Health, Department of Epidemiology and Biostatistics, School of Public Health, Imperial College London, London, UK.

Metabolomics and epigenomics have been used to develop 'ageing clocks' that assess biological age and identify 'accelerated ageing'. While metabolites are subject to short-term variation, DNA methylation (DNAm) may capture longer-term metabolic changes. We aimed to develop a hybrid DNAm-metabolic clock using DNAm as metabolite surrogates ('DNAm-metabolites') for age prediction.

Caenorhabditis Elegans as a Model for Environmental Epigenetics.

Curr Environ Health Rep

January 2025

Institute for Society and Genetics, University of California, Boyer Hall, Room 332, 611 Charles E Young Dr E., UCLA, Los Angeles, CA, 90095, USA.

Purpose Of Review: The burgeoning field of environmental epigenetics has revealed the malleability of the epigenome and uncovered numerous instances of its sensitivity to environmental influences; however, pinpointing specific mechanisms that tie together environmental triggers, epigenetic pathways, and organismal responses has proven difficult. This article describes how Caenorhabditis elegans can fill this gap, serving as a useful model for the discovery of molecular epigenetic mechanisms that are conserved in humans.

Recent Findings: Recent results show that environmental stressors such as methylmercury, arsenite, starvation, heat, bacterial infection, and mitochondrial inhibitors can all have profound effects on the epigenome, with some insults showing epigenetic and organismal effects for multiple generations.

Systemic lupus erythematosus (SLE) patients are 90% women and over three times more likely to die of cardiovascular disease than women in the general population. Chest pain with no obstructive cardiac disease is associated with coronary microvascular disease (CMD), where narrowing of the small blood vessels can lead to ischemia, and frequently reported by SLE patients. Using whole blood RNA samples, we asked whether gene signatures discriminate SLE patients with coronary microvascular dysfunction (CMD) on cardiac MRI (n = 4) from those without (n = 7) and whether any signaling pathway is linked to the underlying pathobiology of SLE CMD.

The Janus kinase/signal transducer and activator of transfection (JAK/STAT) system is comprised of multiple cell surface receptors, receptor tyrosine kinases, and signal transducers that are key components of numerous systems involved in malignancy, inflammation, immune surveillance and development, cellular proliferation, metabolism, differentiation, apoptosis, and hematologic disorders, all of which when disrupted can produce severe disease. Nevertheless, small molecule inhibitors of the four known JAKs, termed JAKinibs, have found therapeutic indications for a broad category of diseases. In this perspective, I will summarize the development of JAK inhibitors, whose origins were in antiquity, with particular attention to their use in treating patients with inflammatory bowel disease (IBD).

A data-driven latent variable approach to validating the research domain criteria framework.

Nat Commun

January 2025

Department of Psychiatry & Behavioral Sciences, School of Medicine, Stanford University, Stanford, CA, USA.

Despite the widespread use of the Research Domain Criteria (RDoC) framework in psychiatry and neuroscience, recent studies suggest that the RDoC is insufficiently specific or excessively broad relative to the underlying brain circuitry it seeks to elucidate. To address these concerns, we employ a latent variable approach using bifactor analysis. We examine 84 whole-brain task-based fMRI (tfMRI) activation maps from 19 studies with 6192 participants.
