Hypothesis
The study aims to explore the interactions between circRBM33 and miR-15a-5p, EZH1, and how circRBM33 promotes septic acute lung injury via the miR-15a-5p/EZH1 axis.
Conclusion
CircRBM33 improves ALI in septic mice by targeting the miR-15a-5p/EZH1 axis.
Supporting Evidence
- CircRBM33 downregulation ameliorated ALI-induced edema, apoptotic, and inflammatory reactions in mouse lung tissues.
- Apoptosis and inflammation mediated by LPS in MLE-12 cells were ameliorated by circRBM33 downregulation.
- circRBM33 mediated EZH1 expression by competitive adsorption of miR-15a-5p.
Takeaway
This study found that a molecule called circRBM33 helps protect mice from lung injury caused by sepsis by interacting with other molecules.
Methodology
The study involved treating murine lung epithelial cells with LPS, measuring cell viability, apoptosis, oxidative stress levels, and conducting various assays to explore the interactions between circRBM33, miR-15a-5p, and EZH1.
Limitations
The sample size collected in the clinical trial was insufficient, which may cause some errors.
Participant Demographics
60 sepsis patients (34 males and 26 females) and 30 healthy controls (14 males and 16 females).
