Metabolic-dysfunction-associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty (NAFLD), is a highly prevalent metabolic disorder characterized by hepatic steatosis in conjunction with at least one cardiometabolic risk factor, such obesity, type 2 diabetes, hypertension, or dyslipidemia. As global rates of obesity and syndrome continue to rise, MASLD becoming major public health concern, projections indicating substantial increase prevalence over the coming decades. The spectrum ranges from simple metabolic-dysfunction-associated steatohepatitis (MASH), fibrosis, cirrhosis, hepatocellular carcinoma, contributing significant morbidity mortality worldwide. This review delves into molecular mechanisms driving pathogenesis, including dysregulation lipid metabolism, chronic inflammation, oxidative stress, mitochondrial dysfunction, gut microbiota alterations. Recent advances research have highlighted role genetic epigenetic factors progression, well novel therapeutic targets peroxisome proliferator-activated receptors (PPARs), fibroblast growth factors, thyroid hormone receptor beta agonists. Given multifaceted nature MASLD, multidisciplinary approach integrating early diagnosis, insights, lifestyle interventions, personalized therapies critical. underscores urgent need for continued innovative treatment strategies precision medicine approaches halt progression improve patient outcomes.

Background Metabolic dysfunction-associated steatotic liver disease (MASLD) is one of the most widespread chronic diseases and a serious global public health problem. Further research to identify novel risk factors associated with MASLD urgently needed. The non-high-density lipoprotein cholesterol high-density ratio (NHHR) was identified as lipid marker. objective this assess association between NHHR in adults. Methods This cross-sectional study utilized data from 2017–2020 National Health Nutrition Examination Survey (NHANES). diagnosed accordance controlled attenuation parameter scores combination cardiometabolic factors. Multivariate logistic regression analyses, conjunction restricted cubic spline method, were employed investigate risk. Furthermore, subgroup interaction analyses conducted. Results included 5,269 individuals, 2,031 individuals 3,238 without MASLD. Logistic revealed significant positive correlation After confounding adjusted, each unit rise correlated 39% higher probability (OR = 1.39, 95% CI: 1.13–1.69). Subgroup that held steady regardless age, gender, race, poverty-to-income ratio, education level, physical activity, body mass index, diabetes, hypertension, dyslipidemia smoking status ( P for >0.05). In addition, non-linear relationship an S-shaped manner found, inflection point at 1.59.

Untargeted lipidomic analysis of metabolic dysfunction-associated steatohepatitis in women with morbid obesity

PLoS ONE, Год журнала: 2025, Номер 20(3), С. e0318557 - e0318557

Опубликована: Март 4, 2025

Metabolic Dysfunction-Associated Steatohepatitis (MASH) represents the severe condition of Steatotic Liver Disease (MASLD). Currently, there is a need to identify non-invasive biomarkers for an accurate diagnosis MASH. Previously, omics studies identified alterations in lipid metabolites involved MASLD. However, these require validation other cohorts. In this sense, our aim was perform lipidomics circulating metabolite profile We assessed liquid chromatography coupled mass spectrometer-based untargeted lipidomic assay serum samples 216 women with morbid obesity that were stratified according their hepatic into Normal (NL, n = 44), Simple Steatosis (SS, 66) and MASH (n 106). First, we are increased MASLD, composed ceramides, triacylglycerols (TAG) some phospholipids. Then, patients SS have characteristic levels diacylglycerols DG (36:2) (36:4), TAG few phospholipids such as PC (32:1), PE (38:3), (40:6), PI (32:0) (32:1). Later, patients, found deoxycholic acid, set TAG, PC, PE, LPI; while decreased (36:0). Finally, reported panel might be used differentiate from made up 9-HODE LPI (16:0) To conclude, investigation has suggested associated MASLD Specifically, seems discriminatory subjects compared individuals. Thus, could diagnostic tool.

Significance of FXR agonists in MASLD treatment: a deep dive into lipid alteration by analytical techniques

Опубликована: Март 25, 2025

Metabolic dysfunction-associated steatotic liver disease (MASLD) is rapidly emerging as a global health crisis, affecting over 30% of the population and demanding urgent attention. This redefined condition, previously known non-alcoholic fatty (NAFLD), reflects deeper understanding intricate interplay between metabolic dysfunction health. At heart MASLD lies troubling accumulation triglycerides (TGs) in hepatocytes, which precipitates insulin resistance oxidative stress, ultimately leading to more severe forms like steatohepatitis (MASH). Excitingly, recent research has spotlighted farnesoid X receptor (FXR) groundbreaking therapeutic target. FXR not only regulates lipid metabolism but also combats inflammation resistance, making it potential game-changer fight against MASLD. With one FDA-approved drug, resmetirom, currently available, exploration agonists opens new avenues for innovative treatments that could revolutionize patient care. By harnessing power restore balance integrating advanced strategies lipidomics acid profiling, we stand on brink transforming how approach its associated complications, paving way healthier future. review delves into promising role combating implications related disorders, emphasizing urgency detect manage this burgeoning epidemic.

Empagliflozin Alleviates Hepatic Steatosis and Oxidative Stress via the NRF1 Pathway in High-Fat Diet-Induced Mouse Model of Metabolic Dysfunction-Associated Steatotic Liver Disease

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(9), С. 4054 - 4054

Опубликована: Апрель 25, 2025

Empagliflozin (EMPA)—a sodium-glucose cotransporter type 2 inhibitor—reduces endoplasmic reticulum (ER) stress, oxidative and inflammation during metabolic dysfunction-associated steatotic liver disease (MASLD) progression. However, the direct effects of EMPA on hepatic lipid metabolism stress are unclear. Through current study, we seek to explore related mechanisms in MASLD. To this end, MASLD was induced C57BL/6J mice using a high-fat diet (HFD); nuclear respiratory factor 1 (NRF1) downregulated via viral transduction (AAV8-shNrf1). Glucose homeostasis histology were assessed, measured. HFD-fed mice-derived tissue samples exhibited more droplets, higher triglyceride levels, elevated ER than chow (CD)-fed mice. attenuated HFD-induced stress. Additionally, HFD significantly decreased NRF1 Sirtuin (SIRT)7 expression compared with CD, which rescued by treatment. these results did not affect insulin resistance or synthesis-related changes upon treatment Nrf1-knockdown Furthermore, alleviated steatosis stress; however, lost Collectively, study suggest that ameliorates reducing attenuating NRF1.
