Insights
The YWHAH gene, encoding 14-3-3n protein, shows distinct expression patterns differentiating infection from sepsis. This finding may aid in early sepsis detection and treatment strategies.
Area of Science:
- Genomics
- Molecular Biology
- Critical Care Medicine
Background:
- Sepsis is a critical condition in intensive care units (ICUs).
- The YWHAH gene encodes the 14-3-3n protein, with prior research focusing on its role in cancer and schizophrenia.
- Limited understanding exists regarding YWHAH gene expression in sepsis.
Purpose of the Study:
- To investigate the role of YWHAH gene expression in differentiating infection from sepsis.
- To identify potential biomarkers for early sepsis detection.
Main Methods:
- Weighted gene correlation network analysis (WGCNA) and Venn plot analysis.
- Analysis of public single-cell transcriptome databases.
- In vitro validation using real-time polymerase chain reaction (RT-PCR).
Main Results:
- YWHAH gene expression was stable in infected individuals and healthy controls.
- Elevated YWHAH expression potentially indicates the transition from infection to sepsis.
- YWHAH expression patterns were distinctive between sepsis and infection cases in transcriptome data and validated by RT-PCR.
Conclusions:
- This study is the first to identify differential YWHAH gene expression between infection and sepsis.
- YWHAH may serve as a potential biomarker for early sepsis diagnosis.
- Findings could inform the development of novel therapeutic strategies for sepsis.
Abstract:
Sepsis, a complex and multifaceted condition, is a common occurrence with serious implications for critically ill patients in the intensive care unit (ICU). The YWHAH gene encodes the 14-3-3n protein, a member of the 14-3-3 protein family. While existing research primarily focuses on the role of 14-3-3n in conditions such as schizophrenia and various cancers, our study revealed that the expression of the YWHAH gene remained relatively stable in both infected individuals and healthy controls. Through Venn plot analysis following weighted gene correlation network analysis, we observed a potential association between elevated YWHAH expression and the transition from infection to sepsis. In a comprehensive analysis of public single-cell transcriptome databases, the expression of YWHAH was found to be distinctive in cases of sepsis and infection. These findings were corroborated through an in vitro analysis utilizing real-time polymerase chain reaction. This study represents the initial identification of variations in YWHAH gene expression between patients with infection and sepsis, potentially offering insights for the development of early detection and treatment strategies for sepsis.
