Comprehensive Transcriptomic and Single-Cell Analyses Enhanced by Artificial Neural Networks Reveal a Distinct Gene Signature for Early Differentiation of MASL and MASH
To develop a robust molecular model for early identification of disease progression and subtype discrimination between metabolic dysfunction-associated steatotic liver disease (MASL) and metabolic dysfunction-associated steatohepatitis (MASH).
Key Findings:
Identified 656 differentially expressed genes between MASL and MASH, with individual genes showing moderate diagnostic performance.
Six key genes (MMP9, FABP5, TREM2, CTSD, UBD, MAP2K1) were consistently identified, with five upregulated in MASH and MAP2K1 downregulated.
The artificial neural network model achieved an AUC of 0.893 in the validation cohort.
Interpretation:
The study provides a high diagnostic accuracy gene signature for distinguishing MASL from MASH, enhancing understanding of immune metabolic mechanisms in disease progression, particularly in the context of inflammation and cellular stress.
Limitations:
The study may be limited by the sample sizes, which could affect the robustness and generalizability of the findings, and the need for further external validation.
Potential biases in data integration and analysis methods could affect results.
Conclusion:
This research establishes a multicohort machine learning-based gene signature with high diagnostic accuracy for MASL and MASH differentiation.
