Sika Deer antler protein antagonizes the inflammatory response and oxidative damage induced by jellyfish venom.

The investigation into specific treatments for jellyfish stings has consistently presented a significant medical challenge. Sika Deer antler protein (DAP), a valuable component of traditional Chinese medicine (TCM) known for its various pharmacological properties, has been widely utilized for the prevention and treatment of numerous diseases. In this study, proteome analysis and biological activity assays of DAP identified 94 distinct protein components and demonstrated its capability to scavenge free radicals. Moreover, administration of 50 mg/kg DAP notably enhanced survival rates in mice, mitigated increases in hematological indicators and inflammatory markers (IL-6, IL-1β, and TNF-α), and alleviated pathological abnormalities induced by jellyfish venom. Additionally, DAP intervention significantly decreased the hemolysis rate and improved the viability of RAW264.7 cells, while reducing cell apoptosis and oxidative stress. Transcriptome analysis and western blotting of RAW264.7 cells further confirmed that DAP inhibited the activation of the NF-κB and MAPK signaling pathways. Overall, DAP effectively countered the toxicity of jellyfish venom by reducing oxidative damage and inflammatory response, highlighting the potential of TCM in treating jellyfish stings.
