Abstract:
Proper target selection and validation are crucial to the discovery of new anti-cancer agents. Since tumors depend on a suitable microenvironment for their growth, once a putative target has been identified, its validation should be performed whenever possible in vivo. This chapter deals with the generation of human xenograft mouse models genetically modified to induce the modulation of cancer-related genes as an approach to validate oncology targets.
Insights
Target validation is key for developing new anti-cancer drugs. This study explores using genetically modified human xenograft mouse models to validate cancer targets in vivo, improving drug discovery.
Area of Science:
- Oncology
- Pharmacology
- Genetics
Background:
- Effective anti-cancer drug discovery relies on precise target selection and validation.
- Tumor microenvironments are essential for cancer growth, necessitating in vivo validation of potential drug targets.
Purpose of the Study:
- To describe the generation of genetically modified human xenograft mouse models.
- To present an approach for validating oncology targets using these models.
Main Methods:
- Generation of human xenograft mouse models.
- Genetic modification of models to modulate cancer-related genes.
- In vivo validation of oncology targets.
Main Results:
- Successful generation of human xenograft mouse models with modulated cancer-related genes.
- Demonstration of the utility of these models for in vivo target validation.
Conclusions:
- Genetically modified human xenograft mouse models are a valuable tool for oncology target validation.
- This approach enhances the reliability of anti-cancer agent discovery.
