This state-of-the-art review proposes a revised Microbiome-Metabolokine-Adipokine (MMA) Axis as a focused framework linking gut microbial metabolic signals with enteroendocrine, hepatic, and adipose responses and the stress-responsive metabolokines fibroblast growth factor 21 (FGF21) and growth differentiation factor 15 (GDF15). Microbiome-derived and microbiome-modified signals, including short-chain fatty acids, bile acids, branched-chain amino acid-related metabolites, tryptophan-derived metabolites, and microbial inflammatory products, can influence intestinal receptor signaling, incretin secretion, hepatic nutrient sensing, adipose lipid buffering, and systemic insulin sensitivity. Within this network, FGF21 and GDF15 are positioned as distinct but complementary adaptive endocrine signals rather than components of a fixed sequential pathway: FGF21 predominantly coordinates responses to nutrient and metabolic stress, whereas GDF15 communicates broader cellular stress through GFRAL-RET-dependent regulation of nutrient intake and energy balance. Importantly, persistent elevation of either metabolokine during insulin-resistant states should not automatically be interpreted as endocrine resistance or maladaptation. We instead propose that progression toward insulin resistance reflects a context-dependent mismatch between increasing metabolic stress and the capacity of integrated endocrine responses to maintain metabolic flexibility and substrate homeostasis. Current evidence strongly supports individual microbiome-metabolite, enteroendocrine, hepatic, adipose, FGF21, and GDF15 signaling modules, but a direct causal microbiome-FGF21-GDF15 sequence has not been established in humans. The revised MMA Axis therefore provides a testable framework for defining how microbiome-derived metabolic signals interface with host endocrine adaptation during the development of insulin resistance.</p>","PeriodicalId":11544,"journal":{"name":"Endocrine reviews","volume":" ","pages":""},"PeriodicalIF":23.9,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149220076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These include alterations in lipoproteins and various metabolites, such as lipids, fatty acids, and amino acids, resulting in a more atherogenic profile and, in some cases, an increased risk in cardiovascular disease (CVD). CVD remains the leading cause of death among women, and lipid profiles change substantially in postmenopause, representing a key sex-specific risk factor. Thus, elucidating the metabolic pathways affected during menopause is crucial to reducing the burden of menopause-related conditions. However, the underlying molecular mechanisms of this increased metabolic burden remain incompletely understood. Recent advances in metabolomic technologies, including mass spectrometry (MS), nuclear magnetic resonance (NMR), and computational tools, have greatly improved our ability to characterize these metabolic shifts.

The fetal glucocorticoid surge is conserved across mammalian species, but mechanisms driving the surge differ. Preterm birth interrupts fetal maturation because babies are born before the rise in endogenous glucocorticoids occurs, placing the newborn at greater risk of morbidity and mortality. In particular, lung immaturity increases risk of short-term and long-term respiratory disease. Antenatal corticosteroids (ACS) are routinely administered to women at risk of preterm birth to mimic the missed maturational signal of elevated glucocorticoids. Consequently, ACS improve neonatal survival and respiratory outcomes. Clinical guidelines universally recommend ACS use, but recommended regimens, gestational age limits, and use in settings of preexisting maternal conditions vary. Importantly, preterm infants have variable responsiveness to ACS treatment, and do not benefit equally. While male fetal sex and fetal growth restriction may be associated with lower ACS responsiveness, there is limited understanding of underlying factors. Emerging evidence points to differential glucocorticoid receptor isoform expression and elevated pretreatment plasma cortisol concentrations as potential contributors to variable ACS response. Improved insight into underlying mechanisms is crucial for identifying responsive subgroups and optimizing ACS treatment beyond the current one-size-fits-all approach to enhance health outcomes for preterm infants.</p>","PeriodicalId":11544,"journal":{"name":"Endocrine reviews","volume":" ","pages":"666-701"},"PeriodicalIF":23.9,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13577750/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148004963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of them, DNA methylation has emerged as an important molecular interface between environmental inputs and changes in gene expression. In this review, we provide an overview of the role of DNA methylation in childhood obesity during the key developmental stages, from prenatal life and childhood to adolescence. We also highlight the available evidence from candidate genes and genome-wide association studies implicating critical loci involved in energy homeostasis and adipogenesis, where DNA methylation is altered. Further, we also provide an overview of how maternal obesity, nutritional status, and bariatric surgery shape offspring's methylation profiles and contribute to the increased risk of programming obesity across generations. Although aberrant methylation patterns are consistently associated with altered metabolic phenotypes, disentangling causality remains a significant challenge. Herein, we highlight emerging approaches, such as rigorous longitudinal cohorts, epigenetic Mendelian randomization, and CRISPR-based epigenome editing, that are beginning to provide the analytical clarity needed to move beyond association. Finally, we examine the potential of DNA methylation signatures to inform early risk stratification and prevention possibilities. Although yet to be clinically validated, whole-genome methylation profiling is increasingly integrated with systems biology and multi-omics frameworks, making the identification of robust, clinically actionable markers more promising.

Elevated circulating GDF-15 levels serve as a biomarker of cellular stress and are increased in a wide range of diseases.

Variable surgical outcomes, biochemical recurrence following adrenalectomy, and refined aldosterone synthase (CYP11B2)-based histopathological classifications highlight PA as a disease spectrum driven by disrupted adrenal zonation, cellular plasticity, and diverse aldosterone-driving somatic mutations.

To attenuate the disinhibited hypothalamic-pituitary-adrenal (HPA) axis under endogenous cortisol deficiency, GCs are often administered at supraphysiological doses and at non-physiological timings, particularly to blunt the HPA axis activation in the early morning before awakening. Long-term studies of adults with CAH show increased risk of co-morbidities, which are often associated with chronic excessive GC exposures. To maintain disease control and to mitigate the adverse effects of conventional therapy, alternative approaches have been trialed. Circadian delivery of hydrocortisone with modified-release preparations or continuous subcutaneous infusion achieves better control at the same or lower daily dose than hydrocortisone tablets. GC-sparing therapies, the first being the corticotropin-releasing factor type 1 receptor antagonist crinecerfont, offer a block-and-replace approach, with near-physiologic dosing of GCs and a second agent to reduce precursor accumulation.
