Summary
Transgenic mice, created using gene targeting in embryonic stem cells, advance physiological and disease studies. Newer methods offer conditional gene control for precise research into kidney function and disease models.
Area of Science:
- Molecular Biology
- Genetics
- Physiology
Background:
- Animal transgenesis is crucial for studying physiological and physiopathological processes.
- Gene targeting in embryonic stem (ES) cells enables precise genetic modifications in mice.
- Transgenic mice models enhance understanding of gene function and human diseases.
Purpose of the Study:
- To review animal models in renal tubular physiopathology.
- To highlight advancements in generating sophisticated transgenic animal models.
Main Methods:
- Classical random DNA integration in the mouse genome.
- Gene targeting using totipotent embryonic stem (ES) cells for targeted transgenesis.
- Development of knock-out and knock-in mouse models.
- Generation of models with conditional transgene expression or mutation.
Main Results:
- Transgenic mice facilitate the study of gene function and the creation of disease models.
- Conditional gene expression and mutation models offer spatial and temporal control.
