Accumulation of Lipid Droplets as an Underlying Cause of the Progression of Fatty Liver Disease to Liver Cancer

August 18, 2026 updated by: Luca Valenti:, Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico

Metabolic dysfunction-associated steatotic liver disease (MASLD) is currently the leading cause of chronic liver disease, accounting for an increasing burden of cirrhosis, hepatocellular carcinoma (HCC), and related mortality, thus representing a major emerging public health threat. Currently, the primary unmet clinical needs in progressive MASLD remain the development of non-invasive biomarkers and effective therapeutic options.

The objective is to delineate the pathogenic mechanisms driving the transition from hepatic lipid accumulation to steatohepatitis, fibrosis, and HCC, based on the hypothesis that alterations in lipid droplet (LD) biology within hepatocytes and resident liver cells are early, decisive factors in disease progression. To test this, human genetic studies from well-characterized cohorts will be combined with human liver organoids (HLOs) and artificial intelligence (AI) tools.

Specifically, common and rare genetic variants will be integrated into partitioned polygenic risk scores (pPRS) to link genetic predisposition to specific LD morphological and functional traits. Furthermore, an innovative high-throughput screening platform using multi-omic approaches will be developed to deconvolve the genetic diversity of MASLD through LD profiling. Finally, these data will be integrated via AI algorithms to refine risk stratification, develop new diagnostic and prognostic tools for cirrhosis and HCC, and identify novel therapeutic targets. Ultimately, the identification of high-risk MASLD subtypes through specific LD pathways will enable precision medicine strategies, significantly improving clinical management.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • The retrospective cohort consists of patients previously enrolled in the SERENA, REASON, REVEAL, FOGS, and LIVER BIBLE studies who have provided informed consent for the use of their data.
  • In the SERENA study, inclusion is restricted to patients aged 45-75 with a diagnosis of MASLD, MetALD, or cryptogenic SLD, showing evidence of F3-F4 fibrosis or cirrhosis through histology, imaging, or non-invasive markers (stiffness >7.9 kPa).
  • High-risk profiles, such as those with a family history of HCC or specific genetic variants (PNPLA3, TM6SF2, MBOAT7), are also included.
  • The REASON and REVEAL studies contribute adult patients (≥18 years) who underwent liver biopsies for suspected NASH, liver resections for HCC or other lesions, or whole liver explants.
  • The FOGS study includes individuals aged 14-80 who specifically do not present with MASLD, MetALD, or cryptogenic SLD.
  • The LIVER BIBLE study provides a control group of blood donors (40-65 years) who are overweight or obese and present at least two metabolic risk factors such as hypertension, dyslipidemia, or impaired fasting glucose.
  • The prospective cohort is divided into two distinct groups: a healthy control population and a MASLD/HCC population. Healthy controls must be at least 18 years old with no clinical or imaging evidence of liver disease, no significant metabolic disorders (such as diabetes or severe obesity with BMI >30), and normal liver function tests. Their alcohol consumption must remain below 20g/day for women and 30g/day for men. The MASLD/HCC population includes adults with a confirmed diagnosis of MASLD or MetALD via imaging or histology. This group encompasses the full spectrum of the disease, from simple steatosis to advanced fibrosis, cirrhosis, and HCC. HCC cases must be diagnosed according to AASLD/EASL guidelines and staged using the BCLC system.
  • All prospective participants must provide signed informed consent and have comprehensive clinical and laboratory data available.

Exclusion Criteria:

  • The Retrospective, patients with an alcohol intake exceeding 60/40 g/day (M/F) or those with diagnosed genetic liver conditions-such as hereditary hemochromatosis, Wilson's disease, or Alpha-1 Antitrypsin deficiency-are excluded due to their increased baseline risk for HCC. Additionally, the use of medications known to induce secondary steatosis is a disqualifying factor.
  • The SERENA study, any prior diagnosis of HCC before the study start date or a medical prognosis of less than two years results in exclusion.
  • Prospective participants are excluded if they present with liver diseases of known etiologies other than MASLD, including viral, autoimmune, or purely alcoholic cirrhosis. Genetic liver diseases associated with high HCC risk (e.g., Wilson's disease, Hemochromatosis) and the presence of non-HCC hepatic malignancies, such as cholangiocarcinoma or secondary metastases, are also grounds for exclusion. Furthermore, patients are ineligible if they suffer from severe concurrent comorbidities-such as advanced renal or heart failure or systemic infections-that could interfere with study compliance or data interpretation. Finally, the ongoing use of steatogenic medications remains a strict exclusion criterion for this cohort.

Experimental: A Multicenter Longitudinal Study on the Pathogenetic Drivers of MASLD
The study protocol involves a series of procedural interventions aimed at identifying biomarkers and therapeutic targets for MASLD progression. This includes the collection and processing of liver tissue for the generation of Human Liver Organoids (HLOs), which serve as a primary biological model for testing disease mechanisms. Procedural assessment is further enhanced by the use of HistoIndex digital pathology, a specialized diagnostic device that employs second-harmonic generation (SHG) microscopy for AI-driven, stain-free phenotyping of liver fibrosis and lipid droplet morphology. Additionally, the integration of multi-omic screening platforms constitutes a core technical intervention to deconvolve genetic diversity. These diagnostic and technological interventions are applied alongside standardized clinical monitoring of cohorts (Liver-BIBLE, SERENA, REVEAL, REASON, and FOGS) to correlate molecular data with clinical outcomes such as cirrhosis and HCC development.
Other: Comprehensive Genomic and Transcriptomic Profiling
DNA isolation followed by Whole Exome Sequencing (WES) to identify rare and common genetic variants. This intervention includes single-cell transcriptomics for precise immunophenotyping of liver resident cells and the mapping of cellular heterogeneity across the MASLD spectrum.
Other: Patient-Derived Human Liver Organoid (HLO) Development
Generation and analysis of 3D Human Liver Organoids (HLOs) from patient biological samples. These models are utilized to study lipid droplet (LD) biology, hepatocyte function, and the mechanisms of disease progression in a controlled, patient-specific environment.
Other: AI-Driven Digital Pathology (HistoIndex)
Use of a non-invasive, stain-free imaging system based on second-harmonic generation (SHG) microscopy. This device provides automated, AI-driven quantification of liver fibrosis and detailed morphological assessment of lipid droplets.
Other: Targeted LD Lipidomics
Advanced lipidomic profiling of lipid droplets (LD) conducted on liver samples to identify specific lipid signatures associated with the transition from simple steatosis to hepatocellular carcinoma (HCC).
Other: AI-Integrated Predictive Risk Modeling
Application of artificial intelligence algorithms to integrate multi-omic data (genomic, transcriptomic, lipidomic) with clinical outcomes. This intervention focuses on developing refined risk stratification tools and identifying novel therapeutic targets for cirrhosis and HCC.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of High-Risk MASLD with Advanced Liver Fibrosis
Time Frame: up to 24 months
Presence of significant to advanced liver fibrosis, defined as histological or non-invasive stage >= F2 (evaluated via transient elastography/FibroScan liver stiffness >7.9 kPa, liver biopsy, or validated non-invasive scoring systems such as NAFLD Fibrosis Score, APRI, or FIB-4). The predictive accuracy of multi-level polygenic risk scores (PRS/pPRS) and multi-omic models in stratifying this risk will be evaluated using area under the receiver operating characteristic curve (AUC-ROC) and logistic regression odds ratios.
