Abstract:
Metastatic disease is a main cause of mortality in prostate cancer and remains to be incurable despite emerging new treatment agents. Development of novel treatment agents are confined within the boundaries of our knowledge of bone metastatic prostate cancer. Exploration into the underlying mechanism of metastatic tumorigenesis and treatment resistance will further expose novel targets for novel treatment agents. Up to date, many of these researches have been conducted with animal models which have served as classical tools that play a pivotal role in understanding the fundamental nature of cancer. The ability to reproduce the natural course of prostate cancer would be of profound value. However, currently available models do not reproduce the entire process of tumorigenesis to bone metastasis and are limited to reproducing small portions of the entire process. Therefore, knowledge of available models and understanding the strengths and weaknesses for each model is key to achieve research objectives. In this article, we take an overview of cell line injection animal models and patient derived xenograft models that have been applied to the research of human prostate cancer bone metastasis.
Insights
Understanding animal models is crucial for advancing prostate cancer bone metastasis research. This review examines cell line injection and patient-derived xenograft models, highlighting their strengths and limitations for developing new treatments.
Area of Science:
- Oncology
- Cancer Metastasis Research
- Animal Models in Cancer Study
Background:
- Prostate cancer bone metastasis is a leading cause of mortality and remains incurable.
- Current treatment development is limited by incomplete understanding of bone metastatic prostate cancer mechanisms.
- Novel therapeutic targets require deeper insights into metastatic tumorigenesis and treatment resistance.
Purpose of the Study:
- To provide an overview of animal models used in prostate cancer bone metastasis research.
- To discuss the strengths and limitations of existing models for studying prostate cancer metastasis.
- To inform the selection of appropriate models for achieving specific research objectives.
Main Methods:
- Review of cell line injection animal models for prostate cancer bone metastasis.
- Analysis of patient-derived xenograft (PDX) models in prostate cancer bone metastasis research.
- Evaluation of the utility and limitations of these models in preclinical studies.
Main Results:
- Cell line injection models offer a simplified approach but may not fully recapitulate human disease.
- Patient-derived xenograft models provide a more clinically relevant platform for studying prostate cancer bone metastasis.
- No single model currently reproduces the entire process from tumorigenesis to bone metastasis.
Conclusions:
- Accurate assessment of animal model strengths and weaknesses is essential for effective prostate cancer research.
- Improved models are needed to fully understand and treat prostate cancer bone metastasis.
- Further research utilizing and refining these models will guide the development of novel therapeutic agents.
