Large yellow croaker skin mucus proteome

Proteomics data demonstrate that skin mucus of the air-exposed large yellow croaker had a complex composition, with an unexpectedly high number of proteins (3,209), suggesting its multiple protective mechanisms possibly involved in antioxidant functions, oxygen transport, immune defence, and osmotic and ionic regulation. These results expand our knowledge of skin mucus secretion and function in fish, highlighting its importance in response to stress.

蛋白质组学（Proteomics）数据显示，暴露于空气的大黄鱼皮肤黏液组成复杂，所含蛋白质数量竟高达3209种，这表明其可能具备多种保护机制，涵盖抗氧化功能、氧转运、免疫防御以及渗透压与离子调节等过程。本研究结果拓宽了我们对鱼类皮肤黏液分泌与功能的认知，凸显了其在应对胁迫过程中的重要意义。
