Long non-coding RNA HOTTIP is elevated in sepsis patients and predicts cardiac dysfunction. Knockdown of HOTTIP reduces LPS-induced cell apoptosis and inflammation, suggesting a therapeutic target for sepsis-related heart problems.
Area of Science:
- Molecular Biology
- Cardiology
- Sepsis Research
Background:
- Sepsis frequently leads to cardiac dysfunction.
- The role of long non-coding RNA (lncRNA) HOTTIP in sepsis-induced cardiac dysfunction is under investigation.
Purpose of the Study:
- To explore the clinical significance of lncRNA HOTTIP in sepsis.
- To investigate the association between HOTTIP and sepsis-induced cardiac dysfunction.
Main Methods:
- Serum HOTTIP levels were measured in 120 sepsis patients using RT-qPCR.
- AC16 cells were treated with lipopolysaccharide (LPS) to assess cell viability and apoptosis.
Main Results:
- Elevated serum HOTTIP levels were observed in sepsis patients and correlated with procalcitonin (PCT).
- Serum HOTTIP demonstrated high diagnostic accuracy (AUC=0.927) for sepsis and predicted cardiac dysfunction development.
- HOTTIP knockdown in vitro reduced LPS-induced apoptosis and IL-6 release.
Conclusions:
- LncRNA HOTTIP is a potential biomarker for sepsis and cardiac dysfunction.
- HOTTIP may play a role in LPS-induced myocardial apoptosis and inflammation, suggesting it as a therapeutic target.
