The Fundamental Role of Nutrients for Metabolic Balance and Epigenome Integrity Maintenance
The Fundamental Role of Nutrients for Metabolic Balance and Epigenome Integrity Maintenance
Epigenetic modifications act as crucial regulators of gene activity and are influenced by both internal and external environmental factors, with diet being the most impactful external factor. On the other hand, cellular metabolism encompasses a complex network of biochemical reactions essential for maintaining cellular function, and it impacts every cellular process. Many metabolic cofactors are critical for the activity of chromatin-modifying enzymes, influencing methylation and the global acetylation status of the epigenome. For instance, dietary nutrients, particularly those involved in one-carbon metabolism (e.g., folate, vitamins B12 and B6, riboflavin, methionine, choline, and betaine), take part in the generation of S-adenosylmethionine (SAM), which represents the main methyl donor for DNA and histone methylation; α-ketoglutarate and ascorbic acid (vitamin C) act, respectively, as a co-substrate and cofactor for Ten-eleven Translocation (TET), which is responsible for DNA demethylation; and metabolites such as Acetyl-CoA directly impact histone acetylation, linking metabolism of the TCA cycle to epigenetic regulation. Further, bioactive compounds, such as polyphenols, modulate epigenetic patterns by affecting methylation processes or targeting epigenetic enzymes. Since diet and nutrition play a critical role in shaping epigenome functions and supporting human health, this review offers a comprehensive update on recent advancements in metabolism, epigenetics, and nutrition, providing insights into how nutrients contribute to metabolic balance, epigenome integrity maintenance and, consequently, disease prevention.

The Protective Effects of Trehalose on Gene Expression Linked to Oxidative Stress and Inflammation in Liver Tissue of Adult and Aged Wistar Rats
The Protective Effects of Trehalose on Gene Expression Linked to Oxidative Stress and Inflammation in Liver Tissue of Adult and Aged Wistar Rats
Background: Aging is associated with chronic diseases and increased oxidative stress, particularly affecting liver function. Aging is linked to chronic diseases and heightened oxidative stress, particularly impacting liver function. Recent research has demonstrated that oral administration of trehalose offers multiple benefits for various tissues and organs.Methods: This study investigated the effects of oral trehalose (2% in water) on the gene expression of key markers linked to liver oxidative stress and inflammation in 4-month-old adult and 24-month-old Wistar rats. Thirty-two male Wistar rats (n = 8) were randomly assigned into four groups: adult control, aged control, adult trehalose (2% in water), and aged trehalose, over a treatment period of one month. Following treatment, liver tissues were analyzed using real-time PCR for genes related to oxidative stress (PGC-1α, NRF2, and SOD) and inflammation (NF-κB, IL-1β, TNF-α, and TGF-β).Results: Our findings revealed a significant up-regulation of PGC-1α, NRF2, and SOD in aged trehalose group compared to the aged control (P < 0.001); however, SOD expression increased by trehalose administration in aged rats compared to other 3 groups. Inflammatory markers (NF-κB, IL-1β, TNF-α) were significantly reduced by trehalose, and TGF-β expression, involved in fibrosis, was attenuated exclusively in aged rats compared with controls (P < 0.05).Conclusion: These results suggest that trehalose has a protective effect on hepatic function, particularly in the aging population, and highlight its potential therapeutic role in age-associated liver dysfunction.

Normalization of Immune Response via Chondroitin Sulfate and Fucoidan Targeting N-Acetylgalactosaminidase
Normalization of Immune Response via Chondroitin Sulfate and Fucoidan Targeting N-Acetylgalactosaminidase
This review explores the pharmacological potential of chondroitin sulfate and fucoidan as immunomodulatory agents targeting N-acetylgalactosaminidase (nagalase) to normalize immune responses. Nagalase, an enzyme produced by tumor and virus-infected cells, contributes to immune suppression by deactivating macrophage-activating factor. Both chondroitin sulfate and fucoidan, as representatives of glycosaminoglycans and heteropolysaccharides, exhibit significant potential in inhibiting nagalase activity, thereby restoring immune functionality. Chondroitin sulfate, a key component of the extracellular matrix, demonstrates anti-inflammatory and tissue-regenerative properties by modulating nuclear factor (NF)-κB pathways and cytokine expression. Fucoidan, a sulfated polysaccharide derived from brown seaweed, enhances immune responses through macrophage and natural killer cell activation, while also exhibiting antiviral and anticancer activities. This dual action positions these compounds as promising agents for therapeutic interventions in chronic inflammatory conditions, cancer, and infectious diseases. The synergistic effects of chondroitin sulfate and fucoidan highlight their potential to address the root causes of immune dysregulation. This review aims to elucidate the underlying mechanisms of action and explore the clinical applications of these compounds within the framework of innovative immunotherapeutic strategies. However, current evidence is limited by the predominance of preclinical studies and variability in experimental models. Well-designed clinical trials are needed to validate their efficacy for therapeutic use.
