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:

  • Oncology
  • Preclinical Cancer Research
  • Medical Imaging

Background:

  • Pancreatic ductal adenocarcinoma (PDAC) remains a significant challenge in oncology.
  • Effective preclinical models are crucial for understanding PDAC biology and developing new therapies.
  • Current models may not fully recapitulate the complexity of human PDAC.

Purpose of the Study:

  • To establish and characterize the DSL-6A/C1 murine pancreatic ductal adenocarcinoma (PDAC) tumor model in Lewis rats.
  • To compare this model against existing preclinical tumor models.
  • To identify potential diagnostic and therapeutic targets for PDAC.

Main Methods:

  • Histological analysis of DSL-6A/C1 tumors to confirm PDAC features.
  • Immune cell profiling of the tumor microenvironment.
  • Multiparametric MRI and PET imaging, including 68Ga-FAPI-46 tracer uptake.
  • Validation of imaging findings against histological data.

Main Results:

  • Histology confirmed characteristic PDAC features, including malignant ductal cells and cancer-associated fibroblasts (CAFs).
  • The tumor microenvironment showed increased CD8+ T cells and decreased CD4+ T cells.
  • 68Ga-FAPI-46 PET imaging demonstrated high tracer uptake in tumor tissues.
  • MRI revealed increasing necrosis and contrast uptake in vital tumor areas over time.

Conclusions:

  • The DSL-6A/C1 rat model exhibits high tumorigenicity and sensitivity to 68Ga-FAPI-46.
  • This model serves as a valuable alternative to existing small animal models for PDAC preclinical studies.
  • It facilitates research into PDAC diagnostics, tumor microenvironment, and therapeutic strategies.
