The nonalcoholic fatty liver disease (NAFLD), which is closely related to westernized dietary (WD) patterns, displays a rising epidemiological and economic burden. Since there is no pharmacological therapy approved for this disease, mechanistic studies are warranted. In this work, we investigated the action of carnosine (CAR), a natural dipeptide with several protection roles against oxidative stress in the liver of NAFLD rats. NAFLD was induced by WD-rich sugars and fat, verifying the histological evidence of steatosis. As intraperitoneal administration of CAR reversed liver steatosis, the protein profiles of NAFLD liver and CAR NAFLD liver were evaluated by label-free proteomics approach. A total of 2531 proteins were identified and the 230 and 276 were significantly up- and downregulated, respectively, by CAR treatment of NAFLD rats and involved in fundamental pathways such as oxidative stress and lipid metabolism. Perilipin 2 and apolipoprotein E, components of the plasma membrane of vesicle, resulted in highly downregulated in the CAR-treated NAFLD liver. The advanced bioanalytical approach demonstrated the efficacy of CAR in overcoming the main symptoms of NAFLD, ameliorating the steatosis in the liver.

Background: Cigarette smoking is a leading cause of preventable death worldwide, with its associated diseases and conditions. Emerging evidence suggests that cigarette smoking contributes to a range of pathological metabolic injuries, including diabetes and nonalcoholic fatty liver disease (NAFLD). The impact of gut microbiota on metabolic health and diseases has been observed, but the causality remains uncertain.

Polycystic ovary syndrome (PCOS) is associated with several mild metabolic disorders, including insulin resistance (IR), obesity, and dyslipidemia, as well as with some more severe ones, including type 2 diabetes mellitus, non-alcoholic fatty liver disease (NAFLD), and cardiovascular disease. Clinically, mild metabolic complications of PCOS such as IR or lipid metabolism disorders are the predictors of these more severe ones. So far, there is no reliable single marker that enables defining metabolic risk in patients with PCOS.

Background: The correlation between serum cotinine and fatty liver index (FLI) needs further investigation for the early identification, prevention, and treatment of metabolic dysfunction-associated steatotic liver disease (MASLD).
Methods: Data from the NHANES database spanning from March 2017 to 2018 was used to perform the population-based study to assess the relationship between serum cotinine and FLI. A variance estimation strategy was applied to address the data volatility.

Purpose: Recently, a significant negative correlation has been found between vitamin D (VD) and metabolic associated fatty liver disease (MAFLD), suggesting a potential beneficial role of VD in preventing of MAFLD, while underscoring the importance of exploring its mechanisms.
Methods: The experiment comprised two parts: male C57BL/6J mice (6 weeks) were fed a high-fat diet (HFD) and intraperitoneally injected with vitamin D (VD) (1.68 IU/g/week) for 16 weeks.
