- 口腔医学是指口腔医学.
- 肝病学 肝病学是一种肝病学.
- 炎症性疾病 炎症性疾病
背景情况:
- 牙周炎是一种常见的口腔炎症状况,具有潜在的全身健康影响.
- 牙周病与肝细胞癌 (HCC) 之间存在联系,但潜在的机制尚不清楚.
研究的目的:
- 为了研究实验性牙周炎对非酒精性脂肪肝炎 (NASH) 相关的HCC进展在非酒精性动物模型 (STAM) 小鼠的影响.
- 探索特定分子媒介的作用,如血管蛋白样蛋白2 (ANGPTL2),在这种协会中.
主要方法:
- 在STAM小鼠中诱导实验性牙周炎.
- 肝脏组织的组织病理学和免疫学分析.
- 对TNFα,MMP9,原1和ANGPTL2的基因表达分析.

02:43Mouse 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,...
