Mouse Models of Cancer Study02:43

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Area of Science:

  • Immunology
  • Oncology
  • Zebrafish models

Background:

  • Cancer immunotherapy faces challenges with clinical translation from traditional models.
  • Zebrafish (Danio rerio) offer unique advantages for in vivo studies due to transparency and genetic tractability.
  • They provide high-resolution, real-time imaging of tumor-immune interactions.

Purpose of the Study:

  • To review the application of zebrafish in cancer immunotherapy research.
  • To highlight tools for tracking immune responses and modeling tumor microenvironments.
  • To evaluate zebrafish platforms for drug screening and personalized therapy.

Main Methods:

  • Utilizing transgenic zebrafish and xenograft models.
  • Tracking innate and adaptive immune responses.
  • Employing patient-derived xenografts for personalized therapy assessment ('zAvatars').

Main Results:

  • Zebrafish enable real-time imaging of tumor-immune dynamics.
  • They facilitate modeling of immune evasion and checkpoint molecule expression.
  • Platforms for high-throughput drug screening and personalized medicine are being developed.

Conclusions:

  • Zebrafish are a valuable complementary model for immuno-oncology research.
  • Limitations include temperature sensitivity and differences in immune responses.
  • Future directions involve humanized zebrafish and novel immunotherapies to accelerate clinical translation.
