简介：
Overview
This study outlines a protocol for longitudinal monitoring of therapeutic efficacy in colonic pathologies using a rigid endoscope in mice. The method allows for the assessment of individual tumor responses and potential disease relapse.
Key Study Components
Area of Science
- Neuroscience
- Oncology
- Gastroenterology
Background
- Colitis and cancer models are essential for testing new therapeutics.
- Recombinant human interleukin 11 protein is used to assess therapeutic effects.
- Endoscopy provides real-time monitoring of disease progression.
- Standard techniques often require multiple cohorts, making this method advantageous.
Purpose of Study
- To evaluate the efficacy of therapeutics in colitis and cancer models.
- To monitor individual mouse responses over time.
- To establish better manipulation of cytokine signaling in disease progression.
Methods Used
- Administration of therapeutic agents and DSS to induce colitis.
- Endoscopic monitoring to assess disease burden and therapeutic response.
- Daily monitoring of mouse health and weight.
- Histological analysis post-euthanasia to confirm colitis pathology.
Main Results
- Reduced disease burden observed through endoscopic scoring.
- Weight loss and endoscopic images correlated with treatment efficacy.
- Individual monitoring allowed for detailed assessment of therapeutic effects.
Conclusions
- The protocol enables precise evaluation of therapeutic efficacy in live mice.
- Endoscopic techniques provide significant advantages over traditional methods.
- Further studies can enhance understanding of inflammation and cancer in the colon.
What is the main goal of this study?
The main goal is to test the efficacy of new therapeutics in colitis and cancer models using a rigid endoscope for monitoring.
How does endoscopy improve monitoring?
Endoscopy allows for real-time assessment of individual mice, providing detailed insights into therapeutic responses.
What therapeutic agent is used in the study?
Recombinant human interleukin 11 protein is used to evaluate its effects on induced colonic pathologies.
What are the advantages of this methodology?
It allows for longitudinal monitoring of the same mouse, reducing the need for multiple cohorts and enhancing data accuracy.
What is DSS and its role in the experiment?
DSS, or dextran sulfate sodium, is used to induce acute mucosal damage in mice, mimicking inflammatory bowel disease.
How is the health of the mice monitored during the study?
Mice are monitored daily for stool consistency, presence of blood, and weight to assess their health status.
