Response: The background for this study is the steadily rising prevalence of obesity in the United States, which has been accompanied by an increase in related comorbid conditions, including Metabolic Dysfunction–Associated Steatotic Liver Disease (MASLD). Bariatric surgery and GLP-1 receptor agonists are two commonly used treatment options to address obesity and its associated complications.
While both have demonstrated benefits in weight loss and metabolic improvement, there has been limited direct comparison of their effectiveness specifically in patients with MASLD. Our study aimed to address this gap by comparing clinical outcomes in patients with MASLD treated with GLP-1 receptor agonists versus those treated with bariatric surgery.

MedicalResearch.com: What is the background for this study?
Response: Metabolic dysfunction can lead to several health problems including metabolic dysfunction associated steatotic liver disease (MASLD), is driven by different factors, including: a person’s behavioral or lifestyle factors, environmental factors, and genetics. Limited research exists regarding genetic , epigenetic, or other factors that might impact development of metabolic dysfunction and MASLD. Our group has previously shown that alterations in DNA methylation (a type of epigenetic change), identifiable both in liver tissue and in blood, associate with MASLD and its progression to more severe liver disease. Whether DNA methylation that impacts imprinted gene expression also associates with metabolic dysfunction and MASLD risk remains largely unknown.
In this project, we explored imprinted genes: imprinting is a normal process that regulates genes by silencing one parental copy (either the maternal or the paternal) so that only one copy is expressed. Imprinting is an important biological process for development and has a disproportionate impact on disease - in fact, imprinted genes are hypothesized to affect 1-6% of the human genome. We sought to explore how altered DNA methylation of imprint control regions (ICRs) that help ‘control’ these imprinted genes might impact development of metabolic dysfunction in children (and hence potentially even in adults).
