4-Methylesculetin attenuates inflammatory pain via inhibition of Sp1-TRPV1 and inflammation related signaling pathways.

Background: Discovering lead compounds with anti-inflammatory and analgesic activities from natural products with minimal toxic side effects has been a long-term goal for researchers. 4-Methylesculetin (4-ME), a natural coumarin derivative, has been reported to have anti-inflammatory and antioxidant properties, but its analgesic effect has not yet been studied. This research investigates the analgesic effect and underlying mechanism of 4-ME in peripheral inflammatory pain.

Construction of a Novel Necroptosis-Related Signature in Rat DRG for Neuropathic Pain.

Background: Recent studies have shown necroptosis may play a role in the development of inflammation-associated pain. However, research on the correlation between necroptosis-related genes and neuropathic pain in the dorsal root ganglia (DRG) is limited. This study aims to identify a gene signature related to necroptosis in DRG that can predict neuropathic pain.
