Summary
Researchers identified TIMP1 and IL18 as key genes in acute liver failure (ALF) by analyzing programmed cell death (PCD) pathways. These genes show promise as diagnostic biomarkers and therapeutic targets for ALF, offering new treatment avenues.
Area of Science:
- Hepatology
- Immunology
- Molecular Biology
Background:
- Acute liver failure (ALF) is a critical condition with high mortality.
- Programmed cell death (PCD) is implicated in ALF pathogenesis but its mechanisms are not fully understood.
Purpose of the Study:
- Identify key PCD-related genes in ALF.
- Explore the potential of these genes as biomarkers and therapeutic targets for ALF.
Main Methods:
- Integrated and analyzed three HBV-ALF microarray datasets.
- Performed differential expression analysis, PPI network construction, and functional enrichment.
- Utilized machine learning (LASSO, random forest) for hub gene identification and assessed immune infiltration.
Main Results:
- Identified 109 differentially expressed PCD genes.
- TIMP1 and IL18 were consistently selected as hub genes, showing high diagnostic and prognostic value.
- Found associations between immune infiltration (macrophage polarization) and PCD, with TIMP1/IL18 linked to immune/metabolic pathways.
Conclusions:
- TIMP1 and IL18 are potential diagnostic biomarkers and therapeutic targets for ALF.
- These genes are closely linked to immune infiltration and PCD processes in ALF.
- Findings offer insights into ALF molecular mechanisms and support targeted therapy development.
