概括

软组织瘤 (STTs) 常常影响老年老鼠,特别是古德曼.

科学领域:

比较病理学比较病理学
灵长类瘤学
衰老研究模型研究模型

背景情况:

鼠 (Microcebus spp.) 是一个有趣的动物. 在衰老研究中是有价值的模型.
在被囚禁的老鼠殖民地中观察到新形成性疾病.
软组织瘤 (STT) 占这些瘤的很大一部分.

研究的目的:

综合审查小鼠鼠中介质瘤性疾病.
在这个灵长类动物模型中描述自发性STT的组织形态.
为了确定风险因素和STT在不同老鼠物种和性别的流行率.

主要方法:

在10年期间对瘤疾病的回顾性分析.
组织病理学检查和瘤的分类.
种类和性别之间的STT发生率的统计比较.

主要成果:

性传播疾病发生在大约一半的瘤病例中 (47/94).
古德曼老鼠鼠的STT比例 (87.5%) 比灰色老鼠鼠 (38.5%) 高.
大多数性传播感染是皮下,纤维/肌纤维细胞和高等级 (II/III);女性比男性更容易受到影响.

结论:

鼠,尤其是古德曼鼠,容易患上高等级的性传播感染.
这些发现有助于理解用于衰老研究的非人类灵长类动物的自发瘤.
需要进一步研究小鼠的性传播病原体和性传播病原体的危险因素.

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,...
