Objective:
To investigate the effects of p16 and GM-CSF combined gene therapy on immune response of tumor-bearing mice (Renca).
Methods:
The model of renal tumor-bearing mice was constructed by subcutaneous injection of Renca cells. The tumor-bearing mice were divided into 5 groups at random three days after injection of Renca cells. Different groups of mice were given different treatments. The antitumor immune responses and the survival time of mice were tested. Histopathologic analysis of tumor tissue was done.
Results:
Enhancement of antitumor immune responses and prolongation of survival period were observed more obviously in tumor-bearing mice after combined therapy than in those of the other four groups.
Conclusions:
p16 and GM-CSF combined gene therapy can enhance the antitumor immune responses of mice and inhibit the growth of pre-established renal cell carcinoma.
Insights
Combined p16 and granulocyte-macrophage colony-stimulating factor (GM-CSF) gene therapy significantly boosts antitumor immune responses and survival in renal cell carcinoma models. This approach effectively inhibits tumor growth in pre-established cancers.
Area of Science:
- Immunotherapy
- Oncology
- Gene Therapy
Context:
- Renal cell carcinoma (RCC) remains a significant clinical challenge.
- Developing effective immunotherapeutic strategies is crucial for improving patient outcomes.
- Gene therapy offers a promising avenue for enhancing the body's anti-cancer defenses.
Purpose:
- To evaluate the efficacy of combined p16 and granulocyte-macrophage colony-stimulating factor (GM-CSF) gene therapy.
- To assess the impact of this combined therapy on antitumor immune responses.
- To determine the effect on survival rates and tumor growth in a murine model of renal cell carcinoma.
Summary:
- Mice with Renca renal tumors received combined p16 and GM-CSF gene therapy.
- Treatment led to enhanced antitumor immune responses and prolonged survival.
- Histopathologic analysis confirmed tumor growth inhibition compared to control groups.
Impact:
- Combined p16 and GM-CSF gene therapy demonstrates significant potential for treating renal cell carcinoma.
- This approach enhances the host's immune system to combat established tumors.
- The findings support further investigation of this gene therapy combination in clinical settings.
