Special Issue Information

Dear Colleagues,

Steatotic Liver Disease (SLD), including Metabolic dysfunction-Associated Steatotic Liver Disease (MASLD), Alcohol-associated Liver Disease (ALD) and the mixed form MetALD, represents a major health concern wordwide. In the last years, the burden of liver-related morbidity and mortality is rapidly growing especially because of the global epidemic of SLD. Translational research aims to identify molecular mechanisms relevant to the pathogenesis of diseases in order to discover novel therapeutic targets. This special issue will accept translational studies shedding light on the molecular bases of MASLD, ALD and MetALD with particular interest on the crosstalk between the liver and other organs (particularly the gut, the adipose tissue and the muscle). Translational studies in in vitro and in vivo models of SLD, focusing on glucose metabolism and insulin signaling, lipoprotein metabolism and lipotoxicity, oxidative stress and inflammation, fibrosis and oncogenesis, are welcome. Clinical studies identifying molecular markers for the prediction of liver outcomes are also welcome.

Dr. Federico Salomone

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic progressive hepatopathy in children, and the identification of non-invasive biomarkers is urgently needed. Growth differentiation factor 15 (GDF15) was associated with MASLD in adults. In this study, we investigated the circulating and hepatic levels of GDF15 and their association with liver damage in pediatric MASLD and in a murine model. This observational study included 158 children with biopsy-proven MASLD. Patients with MASLD were categorized into two groups based on steatohepatitis (MASH) presence and evaluated for GDF15 circulating levels, while GDF15 hepatic levels were assessed only in a subset of patients. Children with MASLD exhibited higher levels of circulating GDF15 compared to the controls. Moreover, the MASH subgroup had significantly higher values of GDF15 compared to the Not-MASH subgroup. The GDF15 levels in the MASH subgroup showed a positive correlation with fibrosis. Finally, the hepatic expression of the GDF15 gene correlated with GDF15 circulating levels and with the hepatic expression of the COL1A1 and COL3A1 genes in 15 children with MASLD. In conclusion, our study demonstrated that GDF15 levels are associated with liver damage, reinforcing the potential role of GDF15 as a biomarker for MASLD-related fibrosis in children. Full article

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly NAFLD, is the most prevalent chronic liver disease worldwide. Strongly linked to obesity, type 2 diabetes, and metabolic syndrome, MASLD poses a growing health burden. Despite its high prevalence and risk of progression, no pharmacological treatment is currently approved. This narrative review provides an overview of emerging pharmacological treatments under clinical investigation, with a particular focus on agents recently evaluated in randomized clinical trials. A systematic search of the ClinicalTrials.gov database through to April 2025 was conducted to identify relevant studies. Investigational drugs were categorized by their molecular mechanisms, and data on efficacy, safety, and clinical development phases were summarized. The most extensively studied drug classes include GLP-1 receptor agonists, PPAR agonists, and FXR agonists, as well as inhibitors of ACC and DGAT. These therapies have shown promising effects on hepatic steatosis, liver enzyme levels, and metabolic markers and may be introduced into clinical practice in the near future. Full article
