Mouse models of metastasis: progress and prospects.

Area of Science:

• Oncology
• Cancer Biology
• Translational Research

Background:

• Metastasis is the primary cause of cancer mortality, responsible for over 90% of cancer-related deaths.
• The metastatic cascade involves complex, multi-step processes including cancer cell escape, survival, extravasation, and secondary tumor formation.
• Tumorigenic metastatic capacity is influenced by intrinsic cancer cell genetics/epigenetics and the tumor microenvironment.

Purpose of the Study:

• To critically evaluate the utility and limitations of current mouse models in studying cancer metastasis.
• To highlight recent advancements in understanding metastasis facilitated by these animal models.
• To discuss the application of mouse models in preclinical cancer therapy testing and translational challenges.

Main Methods:

• Review and critical appraisal of existing literature on mouse models of cancer metastasis.
• Analysis of recent research findings derived from the application of these models.
• Examination of the role of mouse models in evaluating therapeutic strategies for metastatic disease.

Main Results:

• Mouse models are indispensable tools for dissecting the intricate stages of the metastatic cascade.
• Advances in mouse models have significantly improved our comprehension of the molecular and cellular mechanisms driving metastasis.
• These models provide a platform for testing novel anti-metastatic therapies, though translation to clinical practice remains a challenge.

Conclusions:

• Mouse models are crucial for advancing our understanding of cancer metastasis and for preclinical therapeutic development.
• Continued refinement and innovative application of mouse models are essential for overcoming the challenges in treating metastatic cancer.
• Bridging the gap between findings in mouse models and effective clinical treatments is a key future direction.
