Animal Models: A Tool for Colon Cancer Research.

Area of Science:

• Oncology
• Translational Research
• Animal Models

Background:

• Preclinical animal research, particularly using mouse models, is fundamental for advancing colorectal cancer (CRC) understanding.
• Models utilizing carcinogens like 1,2-Dimethylhydrazine (DMH) and Azoxymethane (AOM) are key for inducing CRC and studying its development.
• Diverse animal strains and the examination of literature are crucial for assessing the fidelity of CRC stage replication in models.

Purpose of the Study:

• To review and summarize common murine models employed in colorectal cancer (CRC) research.
• To highlight the applications of these animal models in translational research for CRC.
• To discuss the role of animal models in understanding CRC mechanisms, tumor microenvironment, and treatment efficacy.

Main Methods:

• Literature review of preclinical studies involving animal models for colorectal cancer (CRC).
• Analysis of common carcinogen-induced and genetically engineered mouse models for CRC.
• Evaluation of how different animal models replicate human CRC features, including tumor progression and the tumor microenvironment.

Main Results:

• Murine models effectively replicate key aspects of human colorectal cancer (CRC), including angiogenesis and immune responses.
• Both immunocompetent and immunocompromised rodents are utilized for evaluating novel therapeutic strategies, including immunotherapies.
• The reviewed models provide valuable platforms for studying CRC progression, metastasis, and the tumor microenvironment.

Conclusions:

• Animal models, especially murine models, are indispensable tools for preclinical colorectal cancer (CRC) research and drug development.
• These models facilitate the investigation of CRC mechanisms, the tumor microenvironment, and the efficacy of various treatment modalities.
• Continued advancements in animal models are expected to further enhance the study of tumor biology and accelerate translational research in CRC.
