Mouse models of intestinal cancer

Area of Science:

• Oncology
• Genetics
• Translational Medicine

Background:

• Intestinal cancer research relies heavily on accurate preclinical models.
• Understanding the tumor microenvironment and immunotherapy is vital for effective treatment.
• Autochthonous genetically engineered mouse models (GEMMs) are essential for preclinical studies.

Purpose of the Study:

• To provide a comprehensive overview of current murine models for intestinal cancer.
• To discuss the utility of these models in understanding tumor biology and therapeutic testing.
• To highlight the progression from established models to advanced organoid systems.

Main Methods:

• Review of existing literature on murine models of intestinal cancer.
• Analysis of the historical and current applications of models like Apc(Min/+).
• Discussion of state-of-the-art organoid models and their relevance.

Main Results:

• Established models like Apc(Min/+) have been instrumental for over 25 years.
• GEMMs are critical for studying tumor initiation and the tumor microenvironment.
• Advancements include the development of metastatic models and organoid systems.

Conclusions:

• Murine models are indispensable for dissecting intestinal cancer biology.
• These models are key to identifying new therapeutic strategies, including immunotherapy.
• Continued development of sophisticated models will accelerate discoveries in cancer research.
