Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Tumor invasion and metastasis are critical determinants of cancer patient mortality.
• Understanding cancer cell adaptation during metastasis is crucial for developing effective treatments.

Purpose of the Study:

• To review genetically engineered mouse models (GEMMs) used for studying cancer invasion and metastasis.
• To highlight the utility of GEMMs in elucidating molecular mechanisms of metastasis.

Main Methods:

• Assessment of existing literature on genetically engineered mouse models (GEMMs).
• Analysis of how GEMMs facilitate the study of cancer cell adaptation and spread.

Main Results:

• GEMMs provide powerful tools to investigate the complex molecular processes of cancer metastasis.
• These models allow for in vivo studies of cancer cell adaptation to microenvironments encountered during metastasis.

Conclusions:

• Genetically engineered mouse models are invaluable for dissecting the mechanisms of tumor invasion and metastasis.
• Further research using GEMMs will advance our understanding of metastatic disease and inform therapeutic strategies.
