中文摘要: 蹄叶炎是常见的奶牛多发病,严重影响了奶牛生产性能发挥和动物福利,给奶业造成了巨大的经济损失。但是,蹄叶炎的发病机制尚不明确,奶牛蹄叶炎发生发展过程中,血液流变学性质和血浆蛋白质组表达发生了怎样的变化?目前在国内外尚未见到报道。本项目在前期初步研究奶牛蹄叶炎发生后血浆蛋白组差异表达的基础上,采用比较蛋白质组学、血液流变学、生物信息学和病理学等多学科交叉策略,通过比较健康奶牛和急性蹄叶炎奶牛不同发展时期的血液流变学、血浆蛋白组学和生理生化指标变化,筛选疾病发生发展过程中生物标志物,揭示其与蹄叶炎发生发展的内在联系,筛选早期诊断或监测指标和潜在的药物靶标,为进一步阐明蹄叶炎发生发展的分子机制提供科学依据。

英文摘要: Laminitis is a common frequently-occurring disease in dairy cows, which influences severely the production performance and welfare, and causes huge economic losses, but the pathogenesis is not clear. Plasma proteome and hemorheology changes which take place after laminitis in the body are not described in the previous reports. Through proteomic technology, differential expression of plasma proteome was preliminarily studied to screen the differential proteins of laminitis in dairy cows. The aim of the study to compare the hemorheology and proteome changes between the healthy and laminitis cows in different stage based on cross-disciplinary strategy of proteomics, hemorheology and bioinformatics strategies. The results will screen the potential biomarker for early diagnose and drug target, and reveal the relationship of the changes, which provide an important scientific proof for further clarifying laminitis in dairy cows.
