Summary
Researchers developed a conditional Stat1 knockout mouse to study the role of STAT1 in immunity and cancer. This new tool allows for precise deletion of Stat1, enabling the investigation of its cell-specific functions in various biological contexts.
Area of Science:
- Immunology
- Molecular Biology
- Genetics
Background:
- Interferons (IFNs) are crucial cytokines in innate and adaptive immunity.
- IFN signaling relies on the Jak-Stat pathway, with STAT1 activated by all IFN types.
- STAT1 plays a dual role in cancer, acting as both a tumor suppressor and oncogene.
Purpose of the Study:
- To generate and functionally characterize a conditional Stat1 knockout mouse model.
- To provide a tool for investigating cell-autonomous functions of STAT1.
- To explore STAT1's roles in infection and cancer.
Main Methods:
- Generation of a conditional Stat1 knockout mouse.
- Confirmation of the conditional Stat1 locus integrity.
- In vivo deletion of Stat1 using ubiquitous and tissue-specific Cre recombinase.
Main Results:
- Successful generation of a conditional Stat1 knockout mouse.
- Demonstrated integrity of the conditional Stat1 locus.
- Confirmed in vivo deletion of Stat1 via Cre-mediated recombination.
Conclusions:
- The conditional Stat1 null allele is a valuable research tool.
- This model facilitates the study of STAT1's cell-specific functions.
- Enables new investigations into STAT1's roles in host defense and oncogenesis.

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
02:43Mouse 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.
