Key Points

The study demonstrates that 7-DHC reduces inflammation and oxidative stress in macrophages, impacting osteoarthritis progression.
Key evidence shows that 7-DHC inhibits the ROS/MAPK/NF-κB pathway and activates the Nrf2/HO-1 pathway to exert its benefits.
The approach involves analysis of 7-DHC's action on oxidative damage, inflammation, and ferroptosis in macrophages.
This highlights the potential of 7-DHC as a therapeutic strategy for osteoarthritis, requiring further clinical evaluation.

Abstract

7-DHC exerts anti-inflammatory and antioxidant effects by inhibiting the ROS/MAPK/NF-κB pathway and activating the Nrf2/HO-1 pathway. This reduces oxidative damage, inflammation, and ferroptosis in macrophages, thereby delaying OA progression. As a promising therapeutic strategy, 7-DHC may provide new research directions and clinical translational opportunities for OA treatment.
