Cross-sectional designs require careful control of confounding variables, yet essential factors such as genetic predispositions, socioeconomic status, food environment, and family dynamics were not fully addressed. Additionally, behavioral traits like food neophobia, shown by Dos Anjos et al.

The study's lack of dietary pattern analysis, particularly concerning ultra-processed food intake, and absence of age-stratified reliability in dietary reporting limit its interpretability.

Histone 3 lysine 27 (H3K27) modifiers, namely Ezh2, Kdm6a, Kdm6b, Crebbp and Ep300, are vital for the appropriate differentiation and metabolism of adipocytes, as they can either silence or activate transcription. The expansion of perirenal adipose tissue (AT) in obesity is associated with a number of complications, including hypertension and kidney disease. The aim of this study was to assess the expression of H3K27 modifiers and genes involved in adipogenesis and adipocyte metabolism in perirenal AT of HFD-fed and FO-treated (5DHA:1EPA) mice using real-time PCR. This study demonstrates, for the first time, that a high-fat diet (HFD) increases the expression of Kdm6b (H3K27 demethylase) in perirenal AT, and that treatment with FO can completely reverse this effect. Conversely, the expression of the Acly gene, which encodes an enzyme that provides a substrate for histone acetylases, was found to be reduced in HFD-fed mice and this was not reversed by FO treatment. Additionally, transcription factor genes, such as Tbx1, exhibited diminished expression in perirenal AT of mice fed an HFD. These observations suggest that a HFD affects the expression of chromatin modifiers, transcription factors, and metabolic genes in perirenal AT, and that FO can reverse some of these effects, offering a promising avenue for the treatment of obesity.</div></div>","PeriodicalId":19408,"journal":{"name":"Obesity research & clinical practice","volume":"19 2","pages":"Pages 122-129"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143899049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
