Phage therapy in oncology: opportunities for cancer prevention and treatment.

Bacteriophages (phages) are emerging as programmable biological therapeutics in oncology, extending beyond their traditional antimicrobial applications. This review proposes a phage-microbiome-immune-oncology axis that links microbial dynamics, immune modulation, and engineered phages to guide precision cancer prevention and therapy. Phages can eliminate cancer-associated bacteria, remodel the tumor microenvironment, enhance antitumor immunity, and deliver targeted therapeutic payloads. However, several critical challenges must be addressed to realize this therapeutic potential, particularly host immune responses that limit repeat dosing, inefficient tumor penetration, and the need for rigorous clinical validation. By examining phage-host-tumor interactions through robust model systems and highlighting translational opportunities, this review establishes phage therapy as a promising frontier in precision oncology that warrants accelerated clinical development.

From population to individual: advocating personalised digital tools for heat-health early warning in a changing climate.

Escalating heat extremes under climate change are imposing substantial health burdens, with 2023 and 2024 consecutively breaking global temperature records. Mounting evidence suggests that heatwaves elevate the risks of hospitalisation and mortality across multiple disease categories, including ischaemic heart disease, stroke, chronic obstructive pulmonary disease, and acute kidney injury. Nonetheless, most existing heat-health warning systems remain primarily reliant on population-level predictions, and considering individual differences and disease-specific considerations when defining warning levels would benefit the effectiveness of early prevention for high-risk groups. In this Viewpoint, which is based on the framework of precision public health-delivering the right intervention to the right population at the right time-we propose a framework for personalised digital heat-health early warning tools comprising three dimensions: individualised, risk-stratified prediction models that generate tiered early warnings; personalised health prompts coupled with theory-informed behavioural interventions; and adaptive, equity-oriented alert delivery mechanisms tailored to diverse populations. Such tools have the potential to bridge precision disease prevention and climate adaptation, thereby helping to mitigate heat exposure risks and disease burdens, particularly among high-risk populations. Future implementation research will be essential to address substantial challenges related to feasibility, validation, and equity.

Updated ENIGMA recommendations for reporting germline variants in cancer susceptibility genes and their translation into twenty languages.

Genetic testing for cancer susceptibility underpins precision cancer prevention and care. Gaps in the healthcare providers' genetic literacy and an ambiguous lexicon for variant description may hinder proper delivery and clinical application of consistently trustworthy test results. The Evidence-based Network for the Interpretation of Germline Mutant Alleles (ENIGMA) international consortium supports controlled terminology and recommends a framework for reporting germline variants in cancer susceptibility genes, using breast cancer as an exemplar. Moving forward towards terminological coherence across disciplines and borders, the ENIGMA Clinical Working Group launched a multinational effort to release consortium-approved translations of the published recommendations. The herein reported Vocabulary Translation Project offered an opportunity to reappraise and align the reference text to the recent BRCA1 and BRCA2 specifications to the American College of Medical Genetics and Genomics/Association for Molecular Pathology rules by the ENIGMA Variant Curation Expert Panel and to highlight country-specific differences in breast cancer risk assessment and management. The updated recommendations and their 20 translations are now provided as easy to handle documents, covering 11 of the most widely spoken languages in the world. They will contribute to minimised erroneous inferences, more informed decision-making, improved health outcomes and equity in the use of genetic testing for cancer predisposition and in translational oncology.

Nutritional anemias.

The role of the metals, iron and copper, and the vitamins E, folic acid, and B12 in the genesis of nutritional anemias in infancy have been reviewed. All are preventable. The precise requirements for each of these trace elements and vitamins in the small premature infant remain to be defined. The nonhematologic consequences of these nutritional deficiencies require further study. Anemia may prove to be the least important manifestation of the deficiency states.

A hybrid effectiveness-implementation trial to integrate precision skin cancer risk feedback in federally qualified health centers.

BACKGROUND: Skin cancers are the most common type of cancer in the United States, occur in all segments of the population, and are preventable. Our previous research with primary care patients' demonstrated interest in and efficacy of a precision prevention intervention providing feedback on MC1R risk level (higher versus average) in combination with prevention education materials relative to a standard educational intervention. Our current study is a hybrid type 1 effectiveness-implementation trial deployed at six federally-qualified health centers. This paper presents the study protocol. METHODS: A community advisory panel will guide development of study materials and measures. Staff training at each clinic will be completed in-person. Patients will be approached and screened in-person. Those completing genetic testing and the baseline survey will be randomized to the precision versus standard intervention for each risk level with a target sample size of 286 for each combination. Primary outcomes of effectiveness, assessed at 6 and 12 months, include a tanning score (5 items assessing intentional and unintentional tanning), number of sunburns, conduct of a skin self-examination, and electronic health record documentation of clinician-patient communication about skin cancer prevention. Effectiveness comparisons will focus on the precision relative to the standard intervention among higher risk participants. Implementation data will be collected to identify barriers and facilitators. RESULTS: Effectiveness and implementation outcomes will be evaluated following study completion. CONCLUSIONS: Results will guide subsequent scale-up of the precision intervention, including modifications of the intervention as well as methods for implementation.

Physical and nutritional factors in gel culture of mammalian cells.

The growth of human glioma cells, cultured as spherical colonies in agarose gel, stopped after about 10 days for both large and small colonies apparently due to an increased osmolality in the gel. When osmolality was kept under control by addition of distilled water, growth continued. However, a continuous increase in the population-doubling period, similar for both large and small colonies, then was observed. The increase persisted although excess amounts of nutrition were added. When the cells were cultured in liquid suspension above a thin layer of agarose gel and most of the medium was repeatedly changed, the colonies continued to grow beyond the limits in gel cultured. HeLa and hamster embryonic lung cell colonies showed a growth pattern in agarose gel similar to the glioma cells. The results imply that the osmolality must be kept under precise control to prevent growth inhibition. However, it seems difficult to ascertain optimal growth in gel culture for more than about 2 weeks probably because of the accumulation of toxic products.

Longitudinal Multi-Organ Transcriptomic Atlas of Salt-Induced Hypertension.

BACKGROUND: Salt-sensitive hypertension is a prevalent and clinically significant subtype of hypertension, where increased dietary salt intake elevates blood pressure and causes injury to multiple organ systems. Despite extensive research, dynamic molecular changes and conserved versus organ-specific transcriptional programs in hypertensive multi-organ damage remain poorly understood. Defining complex molecular pathways both in a temporal sequence and in an organ-specific manner is essential for developing targeted, precision therapies to mitigate hypertensive disease burden. METHODS: We generated a longitudinal multi-organ transcriptomic atlas of salt-sensitive hypertension using RNA sequencing of kidney cortex, kidney medulla, heart, and liver from Dahl salt-sensitive rats across four disease stages. A comprehensive bioinformatic analysis mapped dynamic transcriptional programs, evaluated 50 biological pathways, and defined upstream regulators. Histological and biochemical assays complemented transcriptomic analysis, while integration with human genome-wide association studies (GWAS) and compound-transcriptome analysis provided translational insights and identified candidate therapeutics. RESULTS: Salt-induced hypertension elicited both shared and tissue-specific transcriptional programs that evolved with disease progression. The kidney medulla showed robust early immune activation with metabolic suppression, while the cortex exhibited transient metabolic activation before declining and initiating immune activation. The liver and heart showed time-dependent metabolic and inflammatory remodeling. Cross-organ comparisons revealed a shared early proliferative response that converged on proinflammatory and fibrotic signatures. Upstream regulator analysis identified 79 time- and tissue-specific transcription factors associated with gene expression dynamics. GWAS integration analysis revealed endocrine signaling, ion transport, lipid metabolism, and detoxification as conserved pathways across species, underscoring the translational relevance of the model and study. Predictive compound-transcriptome analyses identified kinase inhibitors targeting phosphoinositide 3-kinase, mechanistic target of rapamycin and cyclin-dependent kinases as top candidates to counteract maladaptive transcriptional programs. CONCLUSIONS: This study defines temporal and tissue-specific transcriptomic remodeling in salt-sensitive hypertension and highlights the need for precision interventions to prevent progressive organ damage.

Impact of sex differences on microglial function in Alzheimer's disease.

Aging is the strongest risk factor for Alzheimer's disease (AD), a multifactorial neurodegenerative disorder characterized by amyloid-β (Aβ) accumulation, tau pathology (hyperphosphorylated tau and neurofibrillary tangles [NFTs]), and associated neuroinflammatory processes. Age-related cellular and molecular stressors, including mitochondrial dysfunction, genomic instability, and chronic low-grade inflammation, progressively increase vulnerability to neurodegeneration. In parallel, sex is increasingly recognized as a biological variable that shapes AD risk, clinical course, and neuropathological burden. Women account for roughly two-thirds of AD cases, a disparity not fully explained by longevity. Multiple factors likely contribute, including hormonal transitions across the lifespan (particularly menopausal estrogen decline), sex chromosome-linked immune regulation, sex-dependent interactions between genetic risk factors (e.g., APOE4 and TREM2) and brain aging, and differences in vascular risk, cognitive reserve, and sociocultural exposures that influence disease expression and detection. Microglia, the brain's resident immune cells, are sexually dimorphic, and respond to Aβ and tau pathology, modulating inflammatory signaling, synaptic remodeling, and neurovascular dysfunction implicated in AD. Emerging human and experimental evidence indicate that microglial activation states, immunometabolism, and functional responses differ between males and females and may contribute to sex-specific AD trajectories. Here, we synthesize current evidence supporting microglial sexual dimorphism across aging and AD, highlight possible candidates (hormonal signaling, immuno-aging, disease-associated microglial states, and immunometabolic remodeling), and discuss key knowledge gaps toward sex-informed precision approaches for prevention and treatment.

Polycystic ovary syndrome and idiopathic central precocious puberty: two sides of the same coin?

PURPOSE: Several studies have reported an association between central precocious puberty (CPP) and a higher prevalence of polycystic ovary syndrome (PCOS), raising the hypothesis that CPP may act as an early-life indicator of increased PCOS risk. This review investigates the shared genetic, epigenetic, and environmental factors potentially underlying CPP and PCOS, with the aim of clarifying their connection and supporting advances in early detection and management. METHODS: A comprehensive literature review was conducted using the PubMed/MEDLINE database, prioritizing research from the past two decades, supplemented by key studies from earlier years. This research included studies on genetic and epigenetic factors, endocrine-disrupting chemicals (EDCs), and metabolic influences related to CPP and PCOS. Both original research and review articles were selected, focusing on the identification of pathophysiological mechanisms and risk factors linking these disorders. RESULTS: Genome-wide association studies (GWAS) have linked genetic variants in the kisspeptin and neurokinin B signaling pathways to increased gonadotropin-releasing hormone (GnRH) secretion, triggering early puberty. Moreover, increased GnRH pulsatility contributes to elevated luteinizing hormone (LH) levels, altered LH/follicle-stimulating hormone (FSH) ratios, and ovarian hyperandrogenism—key pathophysiological features of PCOS. Additionally, epigenetic modifications, particularly changes in DNA methylation at CpG sites, have been observed in both CPP and PCOS. A hyperandrogenic intrauterine environment and inadequate fetal growth contribute to prenatal epigenetic alterations, while postnatal factors such as obesity, insulin resistance, and exposure to EDCs further influence epigenetic modifications. Although insulin resistance and hyperandrogenism are central features linking CPP to PCOS, the precise mechanisms underlying these associations remain complex and not yet fully elucidated. CONCLUSIONS: Identifying shared genetic and environmental factors influencing early puberty onset and PCOS highlights the importance of close clinical monitoring in early life, though preventive interventions remain unproven. Further research is needed to clarify these mechanisms, which will support the development of more precise prevention and treatment strategies in clinical practice.

Purification of rat intestinal maltase/glucoamylase and its anomalous dissociation either by heat or by low pH.

Maltase-glucoamylase, a microvillous membrane ectoenzyme, was solubilized from rat intestinal mucosa by digestion with papain and subsequently purified to homogeneity with an overall yield of 10--20%. An antibody to the purified enzyme formed a single precipitin line in immunodiffusion experiments with an intestinal homogenate. The enzyme was shown to be an acidic glycoprotein (20% sugar by weight) which contained low amounts of cysteine and no sialic acid. At pH3--6, maltase activity was slowly lost, but the enzyme was re-activated by re-adjustment of the pH to neutrality. However, in the presence of sodium dodecyl sulphate, acid pH values inactivated maltase irreversibly, and at the same time converted the enzyme (mol.wt. 500000 approx.) into five new species with apparent molecular weights ranging from 134000 to 480000 as judged by polyacrylamide-gel electrophoresis. The same five fragments were also formed by boiling the enzyme for brief periods in the presence of sodium dodecyl sulphate or urea either with or without reducing agents. The dissociated species were stable on re-electrophoresis, and amino acid analysis showed them to be very similar to each other and to the original enzyme. The bands migrated anomalously on polyacrylamide gels of different concentration, thereby preventing the assignment of precise molecular weights. It is possible that the five species may represent stable aggregates of a common monomer of the enzyme.

Multi-ancestry genome-wide and transcriptome-wide association analyses identified new risk loci and genes for inflammatory bowel disease.

To advance genetic understanding of inflammatory bowel disease (IBD), we conducted genome-wide association meta-analyses of 63,415 IBD cases of European and East Asian descendants and identified 90 previously unknown risk loci. Integrating multi-ancestry transcriptome-wide association studies (TWAS), cell type-specific TWAS, alternative splicing (AS-WAS), and alternative polyadenylation (APA-WAS) analyses using RNA-seq data from normal colon tissues of 707 European and 364 East Asian individuals, we uncovered 506 high-confidence IBD risk genes, including 384 not previously reported. These genes converge on immune regulation, microbial interaction, and other pathways central to IBD pathogenesis, with over half showing transcriptional dysregulation supported by single-cell and spatial omics analyses. Notably, 46 risk genes are targeted by 225 drugs that have been approved or in Phase II/III trials, including sulfasalazine already used in IBD therapy. Our study findings deepen the understanding of IBD genetics and support the development of precision medicine for its prevention and treatment.

miss-SNF: a multimodal patient similarity network integration approach to handle completely missing data sources.

MOTIVATION: Precision medicine leverages patient-specific multimodal data to improve prevention, diagnosis, prognosis, and treatment of diseases. Advancing precision medicine requires the non-trivial integration of complex, heterogeneous, and potentially high-dimensional data sources, such as multi-omics and clinical data. In the literature, several approaches have been proposed to manage missing data, but are usually limited to the recovery of subsets of features for a subset of patients. A largely overlooked problem is the integration of multiple sources of data when one or more of them are completely missing for a subset of patients, a relatively common condition in clinical practice. RESULTS: We propose miss-Similarity Network Fusion (miss-SNF), a novel general-purpose data integration approach designed to manage completely missing data in the context of patient similarity networks. miss-SNF integrates incomplete unimodal patient similarity networks by leveraging a non-linear message-passing strategy borrowed from the SNF algorithm. miss-SNF is able to recover missing patient similarities and is "task agnostic", in the sense that can integrate partial data for both unsupervised and supervised prediction tasks. Experimental analyses on nine cancer datasets from The Cancer Genome Atlas (TCGA) demonstrate that miss-SNF achieves state-of-the-art results in recovering similarities and in identifying patients subgroups enriched in clinically relevant variables and having differential survival. Moreover, amputation experiments show that miss-SNF supervised prediction of cancer clinical outcomes and Alzheimer's disease diagnosis with completely missing data achieves results comparable to those obtained when all the data are available. AVAILABILITY AND IMPLEMENTATION: miss-SNF code, implemented in R, is available at https://github.com/AnacletoLAB/missSNF.

Biomimetic mesoporous silica nanosphere ameliorate experimental autoimmune uveitis by delivering sCD83.

Autoimmune uveitis (AU) is an autoimmune disease that may lead to blindness, but there are currently no precise targeted therapies for its prevention and treatment. Dendritic cell (DC) is key cell involved in the pathogenesis of AU, and specific regulation of their state can help improve AU. In this work, mesoporous silica nanospheres were loaded with the immunomodulator soluble CD83 (sCD83) and subsequently camouflaged with dendritic cell (DC) membranes to fabricate the nanocarrier DCM@MSN/sCD83 for treating experimental autoimmune uveitis (EAU). Research results show that DCM@MSN/sCD83 effectively alleviated the symptoms of uveitis in EAU, reduced the proportion of CD4+CD25-T cell/CD4+CD25+T cell and the percentage of DC in the eyes and cervical lymph nodes. It also decreased the expression of STING in Müller cell. Furthermore, the efficacy of DCM@MSN/sCD83 was found to be primarily targeting DC, and promoted the expression of IL-10 and TGF-β1 in DC by activating the phosphorylated HIF/STAT3 pathway, to induce the production of CD4+CD25+ T. This effect is superior to nanomedicine loaded with dexamethasone. Moreover，DCM enabled the nanocarriers to efficiently cross the blood-eye barrier and reach cervical lymph nodes, thereby regulating peripheral immunity. This research indicate that cell membrane-modified nanoparticles targeting homologous cells can effectively improve treatment efficiency and duration, which is potential therapy strategy for uveitis.

Examination of the premature infant.

Ophthalmoscopic examination of the premature infant requires binocular indirect ophthalmoscopy, use of an eyelid speculum, and wide pupillary dilatation. Normal and pathologic features unique to the infant eye often are encountered. Familiarity with these features is essential for accurate diagnosis and prevention of unnecessary therapeutic intervention. Supplemental oxygen is the mainstay of supportive therapy for idiopathic respiratory distress syndrome, a common cause for morbidity in premature infants. Arterial oxygen monitoring is essential for survival and for prevention of retrolental fibroplasia, but precise arterial oxygen levels associated with development of retrolental fibroplasia have not been established.

Genetic and Epigenetic Approaches to Opioid Use Disorder.

BACKGROUND: Opioid use disorder (OUD) is a major global-scale social issue affecting public health. The high potential for addiction and dependence makes opioid use a significant concern, contributing to substance-related disorders. Both genetic and environmental factors contribute to the predisposition to OUD, with the opioidergic, dopaminergic, and GABAergic systems playing primary roles in itsonset. METHODS: This narrative review documents the association between genes and their variants related to these three systems, along with current evidence on epigenetic interventions in OUD. Relevant studies investigating candidate-gene associations and molecular mechanisms were synthesized to highlight genetic variants and epigenetic processes linked to OUD. RESULTS: Genetic associations play a prominent role in OUD, with several single-nucleotide variants identified in affected populations. Key genes implicated include OPRM1, OPRD1, OPRK1, PDYN, OPRL1, and POMC from the opioidergic system; DRD1, DRD2, DRD3, DRD4, ANKK1, and COMT from the dopaminergic system; and GABRA2, GABRB3, GABRG2, GAD1, and GAD2 from the GABAergic system. Evidence also indicates that chronic opioid use is associated with epigenetic changes through posttranslational histone modifications and DNA methylation. However, limitations in existing studies include small sample sizes, limited replication, and potential stratification biases. CONCLUSIONS: Although many candidate-gene associations have been proposed for OUD, robust evidence remains limited. Large, ancestrally diverse genome-wide association studies (GWAS) and systematic replication studies are urgently needed. A deeper understanding of the genetic, epigenetic, and neurobiological bases of addiction will be essential for the development of precisely targeted medications to improve prevention and treatment outcomes for OUD.

Diet-responsive proteogenomic effects following short-term restriction of animal products in humans.

The effect of diet on genetic regulation in humans remains largely unexplored. Here, we investigate gene-diet interactions in a unique group of healthy individuals (N = 200) who alternate between omnivory and dietary restriction of animal products for religious reasons. Using longitudinal proteomic and genotype data, we identify diet-responsive cis-pQTLs and highlight regulatory effects on LBR and MSRA, proteins involved in cholesterol and methionine metabolism respectively. LBR-associated cis-pQTL rs74148404 colocalizes with obesity exclusively under dietary restriction, suggesting diet-dependent modulation of genetic risk. We also show that a diet-dependent cis-pQTL for metabolic regulator FGF21 colocalizes with eosinophil and platelet traits pointing to diet-sensitive immunometabolic signalling. By parallel profiling of a continuously omnivorous control group (N = 211), we uncover seasonally dynamic genetic regulation for proteins linked to apoptosis in immune system pathways (MAVS, CASP3, PDLIM7, IL12RB1), effects likely masked by animal product restriction. These findings reveal dynamic diet- and season-sensitive regulatory mechanisms with implications for precision nutrition and individualized disease prevention strategies, and underscore the need to integrate environmental context into genetic studies of health and disease.
