Long noncoding RNA and messenger RNA abnormalities in pediatric sepsis: a preliminary study

Area of Science:

• Genomics
• Molecular Biology
• Pediatric Medicine

Background:

• Sepsis involves a complex, dysregulated inflammatory response with high mortality.
• Long noncoding RNAs (lncRNAs) regulate biological processes, but their role in pediatric sepsis is understudied.
• Limited knowledge exists regarding lncRNA involvement in pediatric sepsis.

Purpose of the Study:

• To explore the expression patterns of lncRNAs and messenger RNAs (mRNAs) in pediatric sepsis.
• To identify potential diagnostic and therapeutic targets for pediatric sepsis.

Main Methods:

• Utilized microarray analysis to detect lncRNA and mRNA expression in pediatric sepsis patients and healthy controls.
• Performed enrichment analysis, receiver operating characteristic (ROC) curve analysis, and co-expression network analysis.
• Validated key findings using quantitative real-time PCR (qPCR).

Main Results:

• Identified 1488 differentially expressed lncRNAs and 1460 differentially expressed mRNAs.
• Constructed a co-expression network, revealing correlations between specific lncRNAs and mRNAs (e.g., lnc-RP11-1220K2.2.1-7 with CXCR1 and CLEC4D).
• Validated differential expression of four lncRNAs and four mRNAs via qPCR.

Conclusions:

• Provides a comprehensive understanding of lncRNA and mRNA involvement in pediatric sepsis.
• Highlights potential candidate lncRNAs and mRNAs for pediatric sepsis diagnosis and treatment.
• Guides future experimental research in pediatric sepsis.
