Polyphenols, epigenetics, and methionine metabolism: unlocking therapeutic potential.
Polyphenols, abundant in tea, fruits, vegetables, and other plant-derived foods, have emerged as key bioactive ingredients in the field of nutritional epigenetics. These polyphenols can modulate epigenetic modifications through endogenous metabolic pathways that are highly sensitive to food signals. Among these, the methionine cycle plays a central role in maintaining the homeostasis of DNA, histone, and RNA methylation by controlling the cellular supply of S-adenosylmethionine (SAM), the universal methyl donor. Dietary polyphenols influence this cycle through multiple mechanisms, including the regulation of methionine adenosyltransferase activity, modulation of SAM biosynthesis, and promotion of S-adenosylhomocysteine clearance. These actions help restore methylation balance and contribute to the dietary prevention of metabolic, inflammatory, and age-related diseases. Furthermore, polyphenols are biotransformed in the gut microbiota to produce metabolites that further influence methionine metabolism and its associated epigenetic modifications. This review provides an overview of dietary polyphenols as functional food supplements that play a role in methionine metabolic homeostasis and epigenetic modification. This review provides new perspectives for the development of precision nutrition strategies, functional foods, and chronic disease prevention approaches. Dietary polyphenols regulate methionine enzymes, restoring SAM/SAH methylation balance.Polyphenols modulate gut microbiota, producing metabolites that enhance epigenetic health.Methionine cycle governs DNA, RNA, and histone methylation via SAM as a methyl donor.Specific polyphenols (EGCG, curcumin, and resveratrol) mitigate diseases via methylation control.
Mild hyperhomocysteinemia alters spatial and recognition memories in male, but not female rats. Are inflammation, blood-brain barrier damage and Tau expression sex-specific predictors?
Homocysteine (Hcy) is a non-proteic amino acid that participates in the remethylation cycle of methionine. Hcy levels in plasma around 16-30 µmol/L are characteristics of mild hyperhomocysteinemia (HHcy), which is a know risk factor for neurodegeneration. Given this, Hcy may serve as an early biomarker of cognitive decline. In the present study, we evaluated behavior in different tasks in adult male and female rats submitted to mild HHcy and analyzed markers of blood-brain barrier (BBB) integrity (aquaporin, occludin, and β-catenin), the expression of p- TAU217, inflammatory mediators (IL-6 and IL-10), and key cellular markers (GFAP, AIF1, and RbFOX3) in the hippocampus and cortex of these animals. Results revealed that mild HHcy induced short-term and spatial memory impairment in adult male rats, accompanied by region-specific alterations in the cortex and hippocampus. In males, we also observed that HHcy reduced occludin content, IL-10 and RbFOX3; in the hippocampus, HHcy increased the expression of IL-10 and AIF1. The female rats did not exhibit memory deficits, o the other hand, the expression of p- TAU217, and GFAP were increased in the cortex of these animals. Together our finding drive that mild HHcy may represent a valuable translational model for studying early-stage cognitive decline and tauopathy, particularly in the context of sex-specific vulnerability.
Activation of USP30 Disrupts Endothelial Cell Function and Aggravates Acute Lung Injury Through Regulating the S-Adenosylmethionine Cycle.
Microvascular dysfunction is a key contributor to the development of acute inflammatory diseases, characterized by heightened vascular hyperpermeability and leukocyte infiltration into interstitial tissues. Despite substantial research efforts, the precise mechanisms remain partially elucidated. Here, it is identified that USP30 is a critical regulator of lung microvascular inflammation and endothelial cell (EC) barrier integrity. Lipopolysaccharide (LPS) induces deubiquitinase activity of USP30. It is demonstrated that USP30 activation exacerbates EC dysfunction. Inhibiting USP30 leads to a 50% attenuation of inflammatory responses in ECs. In vivo, EC-specific USP30-deficient mice exhibit reduced microvascular dysfunction in models of endotoxin-induced and ischemia-reperfusion lung injury. Inhibition of USP30 preserves EC function via a mitophagy-independent mechanism involving the S-adenosylmethionine (SAM) cycle, DNA methylation, and miR-30a-5p expression. Mechanistically, USP30 depletion destabilizes and reduces methionine adenosyltransferase 2A (MAT2A) by deubiquitination, which in turn lowers SAM levels by ≈40%, and decreases global DNA methylation by roughly 35%, thereby resulting in a fourfold upregulation of miR-30a-5p. Elevated miR-30a-5p suppresses MDM2 and NFAT5 expression, contributing to the maintenance of EC function. These findings highlight that targeting USP30 may represent a potential therapeutic strategy warranting further preclinical and clinical exploration in acute lung injury.
Methionine adenosyl-transferase 2A promotes placental angiogenesis by regulating VEGF-A translation via the mTORC1 signalling pathway.
Abnormal placental angiogenesis contributes significantly to fetal growth restriction (FGR) and related complications. Methionine adenosyl-transferase 2A (MAT2A) can regulate the process of embryonic development; however, the role of MAT2A in placental angiogenesis during fetal development remains poorly understood. In this study, placentas from paired normal birth weight (NBW) and FGR piglets were used to quantify placental vascular density and biochemical indexes, while porcine trophoblast cells (pTrs) and porcine vascular endothelial cells (PVECs) were used to investigate the regulatory mechanism of MAT2A on placental angiogenesis. Here, we found that FGR placentas exhibited reduced vascular density and increased glycogen levels. Moreover, FGR placentas showed reduced S-adenosylmethionine (SAM) levels and downregulated protein expression of MAT2A and CD31. Placental SAM levels were positively correlated with vascular density, while MAT2A expression was positively correlated with CD31 expression. Further study showed that MAT2A knockdown disrupted the metabolism of methionine, glycolysis, the tricarboxylic acid cycle and oxidative phosphorylation, and hindered protein synthesis, thereby impairing cell proliferation and migration in pTrs and/or PVECs, and inhibited angiogenesis in a co-culture system. In contrast, SAM supplementation promoted phosphorylation of ribosomal protein S6 kinase 1 (S6K1), downstream of the mammalian target of rapamycin complex 1 signalling pathway, and upregulated vascular endothelial growth factor-A protein expression, thereby increasing endothelial cell tube formation. In conclusion, our study demonstrates the potential of MAT2A in interventional therapy for placental development of FGR. KEY POINTS: Placental vascular density is correlated with decreased S-adenosylmethionine (SAM) levels caused by downregulated adenosyl-transferase 2A (MAT2A) expression. MAT2A regulates the placental mTORC1 signalling pathway and protein synthesis. MAT2A knockdown disrupts methionine metabolism, glycolysis, the tricarboxylic acid cycle and oxidative phosphorylation. MAT2A regulates the proliferation and migration capacity of placental trophoblast and endothelial cells. MAT2A regulates placental angiogenesis via the SAM-mTORC1-S6K1-VEGF-A signalling pathway.
MTHFR allele and one-carbon metabolic profile predict severity of COVID-19.
While the public health burden of SARS-CoV-2 infection has lessened due to natural and vaccine-acquired immunity, emergence of less virulent variants, and antiviral medications, COVID-19 continues to take a significant toll. There are thousands of new hospitalizations and hundreds of deaths per week in the United States, many of whom develop long COVID. Early identification of individuals at high risk of severe COVID-19 is key for monitoring and supporting respiratory status and improving outcomes. Therefore, precision tools for early detection of patients at high risk of severe disease can reduce morbidity and mortality. Here, we report an untargeted, longitudinal plasma metabolomics study of COVID-19 patients. One-carbon metabolism, a pathway previously shown as critical for viral propagation and disease progression, and a potential target for COVID-19 treatment, scored strongly as differentially abundant in patients with severe COVID-19. Targeted metabolite profiling revealed that one arm of the one-carbon metabolism pathway, the methionine cycle, is a major driver of the metabolic profile associated with disease severity. Further, genomic data from the profiled patients revealed a genetic contributor to methionine metabolism and identified the C677T allele of the MTHFR gene as a preexisting contributor to disease trajectory-patients that show aberrant one-carbon metabolite levels and that are homozygous for the MTHFR C677T, have higher incidence of severe COVID. Our results raise the possibility that MTHFR variant status may inform precision COVID-19 treatment strategies.
