Nutrigenomics: A tool to unlock genetic potential of Nigerian indigenous goat breeds.

Nigerian indigenous goats represent a valuable genetic resource for meat and milk production. However, their productivity often falls below their genetic potential because of sub-optimal nutrition. Nutrigenomics offers a revolutionary approach to bridge this gap by exploring the interactions between nutrients and goat genes. This study explores how nutrigenomic tools can be used to identify gene variants associated with feed efficiency, meat quality, and milk production. Various technologies are designed to ensure the realization of genetic potential. Nutrigenomics is aimed at exploiting the noncoding section of an individual's genome, which is disregarded in traditional animal nutrient requirement assessment. Nutrigenomic technology has the potential to unlock the genetic potential of animals and essentially help to confront nutritional challenges and sub-optimal use of available feed resources, particularly in Nigerian indigenous goats, of which there is a dearth of information on their nutritional needs and requirements. This review discusses the potential of nutrigenomics to unlock the genetic potential of Nigerian indigenous goats. In addition, the review discusses the challenges and future directions of nutrigenomic research in Nigerian goats. By implementing nutrigenomic strategies, Nigerian goat production can be revolutionized, leading to increased productivity, improved product quality, and enhanced farmer livelihoods. It is hoped that this review will provide vital information to aid research into the nutrigenomics potential of unlocking the genetic potentials and reproductive performance of Nigerian indigenous goats through nutrition.

Immunomodulatory Effects of Omega-3 Fatty Acids: Mechanistic Insights and Health Implications.

Omega-3 fatty acids play a significant role in immunomodulation, with nutrigenomic approaches highlighting their impact on gene expression related to immune responses. Research indicates that omega-3 fatty acids can modulate inflammatory pathways, potentially reducing chronic inflammation and enhancing immune function. This review discusses the intersection of nutrigenomics and nutriepigenomics, focusing on how omega-3 fatty acids influence gene expression, immune function, and overall health. The immune system is a complex network responsible for defending the body against pathogens and maintaining internal balance. Comprised of innate and adaptive immunity, the system involves various cells, tissues, and organs working together to combat infections and prevent diseases. Omega-3 polyunsaturated fatty acids (PUFAs), particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), play a significant role in modulating the immune system. These fatty acids influence immune cell function, membrane fluidity, and signaling processes, enhancing immune responses and reducing inflammation. Furthermore, EPA and DHA affect several signaling pathways, reducing the expression of proinflammatory cytokines and inhibiting nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation, a critical transcription factor in the inflammatory response. Additionally, they activate PPAR-γ, further diminishing inflammatory gene expression. As precursors to specialized proresolving lipid mediators, EPA and DHA help shift the lipid mediator profile from proinflammatory to antiinflammatory derivatives, thus aiding in the resolution of inflammation.

Identifying Co-Expressed lncRNAs Correlated With Traits of Interest in an Animal Model for Metabolic Diseases in Humans.

Nutrigenomics investigates how nutrients modulate gene expression. Among them, fatty acids (FA) play important roles in regulating gene transcription, while long non-coding RNAs (lncRNAs) may be associated with gene regulation and metabolic diseases. This study aimed to analyze the hepatic transcriptome of pigs, a species frequently used as a model for nutrigenomic studies, to identify novel lncRNAs and their potential target genes in response to diets containing different sources of FA. Seventy-two pigs were fed four diets supplemented with 1.5% soybean oil (control), 3% canola oil, 3% fish oil, and 3% soybean oil. RNA sequencing of liver samples was performed to identify novel lncRNAs. Weighted Gene Co-expression Network Analysis (WGCNA) was used to identify modules associated with phenotypic traits related to lipid metabolism and inflammation. Functional enrichment analyses were then conducted to annotate genes within these modules using Gene Ontology (GO) terms and to assess overlap with Quantitative Trait Loci (QTL). The results revealed 106 novel lncRNAs potentially regulating genes associated with lipid metabolism and immune responses in pigs fed diets with different FA sources. These findings enhance understanding of the regulatory role of lncRNAs in pigs and reinforce their relevance as models for human metabolic diseases.

Nutrition and longevity - diet in centenarians.

BACKGROUND: Nutrition plays a central role in the biological mechanisms that shape aging, health span, and longevity. Micronutrients—including vitamins, trace elements, and polyphenols—support genomic stability, mitochondrial integrity, and antioxidant defense, while dietary patterns rich in plant-based foods modulate inflammation, metabolic regulation, and epigenetic processes. Centenarian populations consuming Mediterranean, Okinawan, Nordic, and Nicoyan diets offer a natural model for understanding how nutrient-rich, minimally processed foods, moderate caloric intake, and balanced lifestyles interact with molecular pathways to extend functional life. MAIN BODY: This review synthesizes current evidence on how micronutrients influence DNA repair, oxidative stress reduction, and mitochondrial protection, particularly through the actions of vitamins C and E, niacin-dependent PARP activity, folate-mediated methylation, and metal cofactors involved in antioxidant enzymes. Plant-based diets rich in fiber and polyphenols enhance microbial diversity and promote beneficial taxa such as Akkermansia and Bifidobacterium, supporting gut barrier integrity and immune balance. Caloric restriction and intermittent fasting activate nutrient-sensing pathways, including AMPK and sirtuins, reduce mTOR activity, and stimulate autophagy, collectively improving cellular resilience. Findings from centenarian regions highlight the convergence of lifestyle, nutrition, and cultural practices that reduce systemic inflammation, maintain metabolic flexibility, and support healthy aging trajectories. CONCLUSIONS: Diet emerges as a decisive modifiable determinant of lifespan and health span. The convergence of molecular nutrition, microbiome composition, and traditional dietary habits underlies the exceptional longevity observed in centenarian populations. Future research should integrate nutrigenomics, metabolomics, and microbiome profiling to clarify causal mechanisms and guide precision nutrition strategies for aging societies.

A Scoping Review of Direct-to-Consumer Nutrigenetic Testing: Mapping Genes and Associated Nutrition Recommendations.

Consumer demand for autonomy in their own health care is fueling the rise of personal genetic testing. Nutrigenetics tests promise tailored dietary recommendations to help consumers achieve their health and well-being goals. To support informed decision-making by both practitioners and consumers, there is a need for a comprehensive evaluation of the current market landscape and the specific nutrition claims being made. A scoping review was completed via an internet search. Companies that provided direct-to-consumer tests with nutritional recommendations were included. Nonhuman, or pediatric tests, and tests requiring a health practitioner to order were excluded. Genes and nutrition recommendations used in the testing panels were mapped, and company characteristics were summarized. The review was prospectively registered with Open Science Framework (DOI: 10.17605/OSF.IO/A4K2R). There were 104 companies providing 204 nutrition-related testing panels that were included. The mean cost was US$234, with North America the most common continent of company registration. Only 56 (54%) companies publicly disclosed the genes used to make nutritional recommendations, with 3309 unique genes identified across testing panels. Micronutrients (n = 1593 genes), cardiovascular health (n = 1446 genes), and weight loss (n = 1383 genes) were the most commonly reported nutrition categories. Posttest support was provided by 55 (53%) companies, but this was often at additional cost (n = 33), and the qualifications of those providing support varied greatly. The expanding nutrigenetics market continues to be unregulated, with high variability in offerings. With thousands of unique genes linked with nutrition recommendations, it is challenging for healthcare practitioners and consumers to keep pace with this dynamic market. Evidence analysis and resources are required to support healthcare practitioners to provide consumers with evidence-based guidance and ensure their best interests are protected.

The advent of precision nutrigeroscience in cancer: from clinic towards molecular biology.

Nutrimental patterns have been deemed to have an impact on cancer development and the response to cancer therapy. Our growing understanding of cancer and host metabolism has highlighted that nutrient availability in the tumor ecosystem is a key factor in inhibiting tumor development. Subsequently, dietary interventions must take into account the specific characteristics of both the cancer and the host, which requires a detailed understanding of the mechanisms that determine the metabolic vulnerabilities in the tumor ecosystem. In this review, we provide an overview of various dietary regimens as interventions in both preclinical models and clinical studies. We discuss how dietary intervention can affect the homeostasis of the tumor ecosystem, including neoplastic, micro- and macro-environmental states that impact cancer progression and therapy. Our emphasis is on the prospects of precision nutrigeroscience, which involves developing individualized therapeutic approaches and predictors based on a thorough exploration of the mechanisms and critical factors. This approach has the potential to enhance the efficacy of anti-cancer treatments and prevention strategies.
