中文摘要: 大蹼铃蟾(Bombina maxima)betagamma-CAT作为第一个从脊椎动物中得到的天然存在的非晶状体betagamma-晶状体蛋白与三叶因子复合物,探索其生理功能对于揭示其在大蹼铃蟾皮肤存在的合理性并进一步揭示哺乳动物非晶状体晶状体蛋白可能的生理功能,有着非常重要的意义。为了揭示其生理功能,我们从大蹼铃蟾皮肤成功培养了皮肤成纤维细胞以及角质形成细胞,并建立了一套比较完善的大蹼铃蟾皮肤细胞培养方法。基于此基础,我们检测了betagamma-CAT对其自身成纤维细胞以及角质形成细胞的效应,结果发现其可以明显地促进它们的迁移,奠定了其作为伤口修复蛋白的生理基础。在体内水平,我们发现腹腔注射betagamma-CAT可以明显抑制因细菌感染引起的大蹼铃蟾腹膜炎的发生。为了更好地在大蹼铃蟾自身研究betagamma-CAT的生理功能,我们对其皮肤组织以及血液进行了转录组测序,获得多达三万多个基因的序列,这位我们今后更深入地研究奠定了良好基础。结合其他基金资助,相应取得了很多超出项目计划的结果,发表多篇SCI 研究论文。

英文摘要: Bombina maxima betagamma-CAT is the first natural existed betagamma-crystallin and trefoil factor complex. Exploring its physiological function is important to understand its reasonability of existing in skin and further understanding the gene function of non-lens betagamma crystallins in mammals. In order to reveal its function in skin, skin fibroblasts and keratinocytes were successfully cultured in vitro. We examined the biological effect of betagamma-CAT on Bombina maxima skin derived cells and the results indicated that betagamma-CAT was able to enhance the cell migration fibroblast and keratinocyte. We also tested the in vivo effect of betagamma-CAT and it can effectively protect Bombnna maxima against bacteria induce peritonitis. For better understanding of the physiological of betagamma-CAT and other skin secretions, we conducted a transcriptome sequencing of Bombina maxima skin and blood, getting up to over thirty thousand uni-gene sequences, fueling the in-depth study of Bombina maxima skin biology. Co-supported by other fundings , We have obtained many results exceeding the programe plan,and have been applied one national patent. Meanwhile several SCI papers have been published.
