背景情况:

鸟类的脱毛,或羽毛的损失,影响各种鸟类,由于营养,荷尔蒙,疾病,压力和遗传等因素.
梅拉诺菲林 (Mlph) 基因的突变与其他物种的脱发相关,但其在家禽中的作用尚不清楚.

研究的目的:

调查梅拉诺菲林 (Mlph) 基因在家禽中羽毛发育和脱毛方面的作用.
建立第一个Mlph淘汰赛模型,用于研究脱发症.

主要方法:

利用CRISPR/Cas9基因编辑技术创建了一个Mlph淘汰赛 (HO) 模型.
观察并记录了Mlph淘汰赛的羽毛发育和质量,从化到年龄较大.

主要成果:

Mlph基因的干扰不会影响化时的羽毛质量,但会导致老的羽毛恶化和脱发症状.
该研究在Mlph淘汰赛家禽模型中确定了一种颜色稀释的脱毛表型.
证实了Mlph基因的破坏导致的羽毛流失和白发表型.

结论:

该Mlph淘汰赛模型是第一个研究Mlph基因与家禽脱发之间的联系的模型.

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
