Abstract:
The knockout mouse is one of the most useful experimental animal systems in which to clarify functions of identified genes in vivo. Numerous knockout mice have been produced, and studies in these models have revealed new aspects in various biological fields. In fair cases, however, mice died during embryogenesis due to complete gene disruption, making it difficult to elucidate functions of given genes in adulthood. To avoid this, conditional gene targeting has been performed and shown to be effective on numerous cases. Here, we will overview established strategies for conditional gene targeting and present the results of our recent studies using the Cre/loxP system in the skin.
Insights
Conditional gene targeting in mice allows researchers to study gene functions in adulthood. This approach, particularly using the Cre/loxP system in skin, overcomes embryonic lethality issues in traditional knockout models.
Area of Science:
- Genetics and Genomics
- Developmental Biology
- Animal Models
Background:
- Knockout mice are vital for in vivo gene function studies.
- Complete gene disruption can cause embryonic lethality, hindering adult gene function analysis.
- Conditional gene targeting offers a solution to study gene roles in adult organisms.
Purpose of the Study:
- To overview established strategies for conditional gene targeting.
- To present recent findings using the Cre/loxP system in mouse skin.
- To elucidate gene functions in adult mice, overcoming developmental limitations.
Main Methods:
- Review of established conditional gene targeting strategies.
- Application of the Cre/loxP recombination system.
- Experimental studies conducted specifically in the skin of genetically modified mice.
Main Results:
- Conditional gene targeting effectively circumvents embryonic lethality associated with complete gene knockout.
- The Cre/loxP system demonstrates utility for targeted gene manipulation in adult mouse models.
- Specific gene functions in the skin were elucidated through this conditional approach.
Conclusions:
