- 药理学 药理学是指药理学的学科.
- 毒理学 毒理学 毒理学
- 瘤学 药物开发 药物开发
背景情况:
- 在临床试验之前,对瘤学药物进行非临床毒性评估是强制性的.
- 瘤学药物可能具有固有的毒性,需要识别潜在的目标器官以监测患者.
- 目前的临床前测试旨在预测临床毒性并确保患者的安全.
研究的目的:
- 评估支持60种小分子瘤学候选药物的临床进入的毒性研究.
- 在动物和非动物模型中,在各种身体系统中识别共同的目标器官.

Toxicity Testing in Animals
70
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...

Mutagenicity and Carcinogenicity
2.1K
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Mouse Models of Cancer Study
6.6K
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,...
