Radix Sanguisorbae Improves Intestinal Barrier in Septic Rats via HIF-1 α/HO-1/Fe2+ Axis.
Liu et al., Chin J Integr Med 2024
DOI: 10.1007/s11655-023-3550-2
Summary of Findings:
The study explored the therapeutic potential of Radix Sanguisorbae (RS, Diyu) in treating sepsis-induced intestinal barrier dysfunction using a rat model and cell culture. The key findings are:
- RS treatment significantly improved survival in septic rats, extending survival time to 56 hours and increasing the 72-hour survival rate to 43.75% (7 out of 16 rats).
- RS enhanced intestinal barrier function, reduced inflammation, and decreased lipid peroxidation and ferroptosis, which are better outcomes compared to the control group treated with Ringer’s solution alone.
- Network pharmacology predictions suggested that the beneficial effects of RS might be mediated through the ferroptosis and HIF-1α signaling pathways.
- Experimental validation confirmed the involvement of the HIF-1α/heme oxygenase-1/Fe2+ axis in the protective effects of RS against sepsis.
Importance:
This research is important as it identifies RS as a potential therapeutic agent for sepsis, specifically targeting intestinal barrier dysfunction and ferroptosis. The study also provides insights into the underlying mechanisms of RS’s protective effects, which could guide future therapeutic strategies for sepsis treatment.
Contribution to Literature:
The study contributes to the current literature by demonstrating the efficacy of RS in a septic rat model and by elucidating the molecular pathways involved in its protective effects, particularly highlighting the role of ferroptosis inhibition and the HIF-1α signaling pathway.
