Clinical Report: Identification of PGD, MAPK14, and KRAS as Biomarkers
Overview
This study identifies PGD, MAPK14, and KRAS as biomarkers for neonatal sepsis, supported by machine learning and immune infiltration assessments.
Background
Neonatal sepsis is a critical condition with high mortality rates, particularly in low- and middle-income countries. Current diagnostic methods are often slow, highlighting the need for reliable biomarkers.
Data Highlights
Biomarker
AUC
PGD
> 0.79
MAPK14
> 0.79
KRAS
> 0.79
Key Findings
PGD, MAPK14, and KRAS were identified as biomarkers through multiple machine learning models.
All three biomarkers showed diagnostic performance with AUC values greater than 0.79.
Immune infiltration analysis indicated increased neutrophils and Tregs, with decreased CD8+ T cells in sepsis patients.
Molecular docking revealed dasatinib and gefitinib as binders to MAPK14 and KRAS.
In vitro studies confirmed upregulation of PGD, MAPK14, and KRAS expression following LPS stimulation.
Candidate drugs inhibited macrophage viability in experimental settings.
Clinical Implications
The identification of PGD, MAPK14, and KRAS as biomarkers could facilitate earlier diagnosis of neonatal sepsis, potentially improving clinical outcomes. The study also suggests that dasatinib and gefitinib may have therapeutic potential in managing sepsis-related inflammation.
Conclusion
PGD, MAPK14, and KRAS are identified as biomarkers for neonatal sepsis. Further investigation into their roles in sepsis pathogenesis is warranted.
