Channa striata are speculated to contain bioactive proteins with the ability to enhancing wound healing. It is commonly consumed after surgery for a faster recovery of the wound.
To identify the bioactive proteins and evaluate their ability in cell proliferation and angiogenesis promotion.
Freeze-Dried Water Extracts (FDWE) and Spray-Dried Water Extracts (SDWE) of C. striata were tested with MTT assay using EA.hy926 endothelial cell line and ex-vivo aortic ring assay. Later the proteins were fractionated and analysed using an LC-QTOF mass spectrometer. The data generated were matched with human gene database for protein similarity and pathway identification.
Both samples have shown positive cell proliferation and pro-angiogenic activity. Four essential proteins/genes were identified, which are collagen type XI, actin 1, myosin light chain and myosin heavy chain. The pathways discovered that related to these proteins are integrin pathway, Slit-Robo signalling pathway and immune response C-C Chemokine Receptor-3 signalling pathway in eosinophils, which contribute towards wound healing mechanism.
The results presented have demonstrated that C. striata FDWE and SDWE protein fractions contain bioactive proteins that are highly similar to human proteins and thus could be involved in the wound healing process via specific biological pathways.
推测条纹鳢含有具有促进伤口愈合能力的生物活性蛋白。人们通常在手术后食用它以促进伤口更快恢复。
鉴定生物活性蛋白并评估其在细胞增殖和促进血管生成方面的能力。
使用EA.hy926内皮细胞系通过MTT法以及体外主动脉环试验对条纹鳢的冻干水提取物(FDWE)和喷雾干燥水提取物(SDWE)进行测试。随后对蛋白质进行分级分离,并使用液相色谱 - 四极杆飞行时间质谱仪进行分析。所产生的数据与人类基因数据库进行比对,以确定蛋白质相似性和途径。
两个样品均显示出阳性细胞增殖和促血管生成活性。鉴定出四种重要的蛋白质/基因,即XI型胶原蛋白、肌动蛋白1、肌球蛋白轻链和肌球蛋白重链。发现与这些蛋白质相关的途径有整合素途径、Slit - Robo信号通路以及嗜酸性粒细胞中的免疫反应C - C趋化因子受体 - 3信号通路,这些都有助于伤口愈合机制。
所呈现的结果表明,条纹鳢的FDWE和SDWE蛋白组分含有与人类蛋白质高度相似的生物活性蛋白,因此可能通过特定的生物学途径参与伤口愈合过程。
