Bee pollen is characterized by an exceptional diversity and abundance of micronutrients bioactive phytochemicals. This richness remains very sparsely investigated, but accumulating evidence strongly supports a promising future for bee in human nutrition medicine. Epigenetic regulation among the most compelling biomedical topics that remain completely untapped derivative research. In our current research, we identified numerous ubiquitous compounds are consistently present this matrix, regardless its botanical geographical origins, have been well studied documented as epigenetic regulators recent years. Given relative newness both research studies within nutritional, pharmaceutical, medical sciences, review aims to bridge these valuable fields advance related experimental investigations. To best knowledge, first work has aimed comprehensively investigate modulatory potential compounds. Our findings also unveiled several intriguing phenomena, such dual effect same compound depending on cellular context or some cross-generational heritability traits. Although whole extract still lacking, study clearly indicates avenue worth further We hope constitutes foundational cornerstone investigations

Biological ageing is a time-dependent process that has implications for health and disease. Cellular senescence key driver in age-related diseases. Senotherapeutic agents have been shown to slow biological by eliminating senescent mammalian cells. Given the increasing awareness of gut microbiome regulating human health, this study aimed investigate effects senotherapeutic as pharmacological interventions on microbiota. In study, bidirectional four agents, quercetin, fisetin, dasatinib, sirolimus, with microbiota sourced from healthy donors were investigated. The results revealed quercetin was completely biotransformed within six hours, while dasatinib most stable compounds. Additionally, metagenomic analysis confirmed all compounds increased abundance bacterial species associated (e.g., Bacteroides fragilis, Bifidobacterium longum, Veillonella parvula), decreased pathogenic bacteria primarily diseases Enterococcus faecalis Streptococcus spp.). findings provide comprehensive understanding pharmacobiomics interventions, highlighting potential microbiome-targeted senolytics promoting ageing.

One-carbon metabolism is a critical pathway for epigenetic mechanisms. Circulating biomarkers of one-carbon have been associated with changes in nuclear DNA methylation levels individuals affected by age-related diseases. More and more studies are showing that even mitochondrial (mtDNA) could be methylated. In particular, the displacement (D-loop) region modulates gene expression replication mtDNA and, when altered, can contribute to development human illnesses. However, no study until now has demonstrated an association between circulating D-loop levels.

Abstract Aging triggers physiological changes in organisms that are tightly linked to metabolic changes. Senolytics targeting many fundamental aging processes currently being developed. However, the host response natural senescence and molecular mechanism underlying antiaging benefits of senolytics remain poorly understood. In this study, we investigated during based on Caenorhabditis elegans model pinpointed potential biomarkers senolytics. These results suggest age-dependent occur C elegans. Betaine was identified as a crucial metabolite process. We explored effects interventions by administering 3 drugs—metformin, quercetin, minocycline—to nematodes. Notably, betaine expression significantly increased under drug treatments. Our findings demonstrated supplementation extends lifespan, primarily through pathways associated with forkhead box transcription factor (FoxO) signaling pathway, p38-mitogen-activated protein kinase (MAPK) autophagy, longevity regulating target rapamycin (mTOR) pathway. addition, autophagy free radicals altered betaine-treated Overall, found is critical extend lifespan nematodes increasing levels promoting antioxidant activity. This finding suggests could be novel therapeutic for longevity.

Autophagy, a vital cell process, has garnered attention for its role in various diseases and potential therapeutic interventions. Dysregulation of autophagy contributes to conditions such as metabolic diseases, neurodegenerative disorders, cancer. In diabetes, plays crucial islet β-cell maintenance glucose homeostasis, offering targets intervention. Nutrigenomics, which explores how dietary components interact with the genome, emerged promising avenue disease management. It sheds light on diet influences gene expression cellular processes, personalized approaches prevention Studies have showed impact specific components, polyphenols omega-3 fatty acids, suggesting their benefits disorders. cancer, autophagy's dual either suppressing tumorigenesis or promoting cancer survival underscores importance understanding modulation through Combined conventional chemotherapy drugs, compounds show synergistic effects treatment.

ABSTRACT Carbon-14 (C-14) has been a major contributor to the human radioactive exposure dose, as it is released into environment from nuclear industry in larger quantities compared other radionuclides. This most abundant nuclide enters biosphere organically bound C-14 (OBC-14), posing potential threat public health. Yet, remains unknown how this relatively low radiotoxic induces health risks via chemical effects, such isotope effect. By establishing trophic transfer model involving algae (Scenedesmus obliquus), daphnia (Daphnia magna) and zebrafish (Danio rerio), we demonstrate that rapid incorporation transformation of inorganic by OBC-14 facilitates blending biomolecules zebrafish. We find internalized persistently retained brain zebrafish, affecting DNA methylation causing alterations neuropathology. Global tracing metabolomics with further reveals involvement various critical metabolic pathways, including one-carbon metabolism nucleotide metabolism. thus characterize kinetic effects for 12C/14C key reactions these pathways through experiments density functional theory computations, showing isotopic substitution carbon biochemicals regulates disrupting reaction ratios effects. Our results suggest discharged can be biotransformed impact providing new insights understanding risk C-14, which traditionally considered nuclide.
