The optimized expression technology of marine animal-sourced antimicrobial peptides in Pichia pastoris and the development of antimicrobial peptide as feedstuff additive [PDF]
, 2015 抗生素污染问题是目前影响我国水产养殖业可持续健康发展的重大科技问题，抗生素（antibiotics）作为常用抗菌药物，被广泛应用于水产养殖业，但是抗生素超标所引起的细菌耐药性问题已成为全球公共健康问题，因此寻找抗生素的有效替代品是目前国内外本领域的研究热点之一。抗菌肽（antimicrobialpeptide）是先天性免疫的重要组分，广泛存在于生物界的各个门类，进化上相对保守，具有广谱抗菌活性、且不会产生细菌耐药性，被预言为最有希望替代抗生素的天然药物，具有广阔的应用前景 ...

Function and mechanism of Repulsive Guidance Molecule RGMb/Dragon during Colorectal Cancer progression [PDF]
, 2016 结直肠癌是我国甚至全球范围内最常见的肿瘤之一，也是肿瘤相关死亡的主要原因之一。及时而有效的诊断是降低结直肠癌死亡率的重要措施。除了临床上常规的诊断及治疗方法外，人们也在不断致力于新型肿瘤标志物的研究，以进一步明确结直肠癌发生发展的机制。排斥导向分子(RGM)家族成员RGMb，又名Dragon，作为骨形态发生蛋白(Bonemorphogeneticprotein，BMP)通路的辅助受体，不但承载着胚胎发生、神经修复和肾脏正常生理功能，还与各种上皮来源肿瘤的发生发展密切相关。然而，RGMb ...
