The UCI Transgenic Mouse Facility represents a cornerstone in modern biomedical research, providing essential support for the creation and study of genetically modified mouse models. These models play a crucial role in understanding human diseases, testing new therapies, and exploring complex genetic mechanisms. By enabling precise manipulation of the mouse genome, the facility helps researchers simulate human genetic conditions in a controlled laboratory environment, which has become indispensable for advances in genetics, neuroscience, cancer research, and developmental biology.
Overview of the UCI Transgenic Mouse Facility
The UCI Transgenic Mouse Facility, located at the University of California, Irvine, is dedicated to producing and maintaining genetically engineered mice for scientific research. This specialized facility offers services ranging from microinjection of DNA constructs into embryos to the establishment of transgenic and knockout mouse lines. Its mission is to support academic and industry research by providing high-quality animal models and expertise in advanced genetic techniques.
Services Offered
The facility provides a comprehensive range of services designed to meet the diverse needs of researchers working on genetic studies. Key services include
- Transgenic Mouse ProductionIntroduction of foreign DNA into the mouse genome to create models that express new genes or altered versions of existing genes.
- Knockout and Knock-in ModelsTargeted gene disruption or insertion, allowing researchers to study the effects of specific genes on disease progression, development, or physiology.
- Embryo Manipulation and MicroinjectionPrecise injection of DNA or RNA into fertilized embryos, followed by implantation into surrogate mothers to establish new mouse lines.
- CryopreservationLong-term storage of embryos or sperm for future use, ensuring the preservation of valuable genetic lines.
- Genotyping and Colony ManagementVerification of genetic modifications and careful maintenance of breeding colonies to ensure the reliability of experimental results.
Importance of Transgenic Mouse Models in Research
Transgenic mouse models are essential tools in biomedical research. By mimicking human genetic conditions, these mice allow scientists to investigate disease mechanisms in ways that would be impossible in humans. For example, transgenic mice have been used to study Alzheimer’s disease, diabetes, cancer, and cardiovascular disorders. Knockout mice, where a specific gene is disabled, provide insights into gene function and help identify potential therapeutic targets.
