In human research, significant advancement has been achieved with molecular biological tools. But for a better understanding of disease biology, an animal model like the mouse model is needed to have genetic similarities with humans.
For preclinical studies, mouse models are commonly used gizmo to predict the disease outcome in humans. The role of the mouse model is significant due to being genetically similar (99%) to humans and successfully used for various aspects of human research, including genome-related diseases, immunological disorders, oncological conditions, pharmacological studies, and reproduction-related studies. To elaborate on the role of the mouse model, here are the reasons why mouse models are used in gene therapy research:
- They are biologically similar to humans
The mouse has similarities with a human concerning genetics, anatomy, and physiology. For example, the laboratory mouse used for human studies has genetic similarities with wild-type mice. These are better than insects, and worms for exploring the complex biological systems of humans (skeletal, nervous, cardiovascular, endocrine, and immune) in similarity with human mice naturally acquire diseases associated with these systems. In addition, the immunologically incompetent mouse can be used for growing human tissues (healthy and diseased) which will be an important gizmo for cancer and AIDs research.
- They can be manipulated to mimic human disease (condition)
The role of the mouse model is pivotal for studying pathology and control of complex diseases, i.e., hypertension, atherosclerosis, genetic disorders, and immunological disorders. The use of mice helps to look deep into genetic involvement in diseases. The mouse can be easily manipulated (insertion and deletion of the gene are easy and better) compared to other animals. Such characteristics help in exploring genetic diseases.
- They can be inbred to yield genetically identical strains
The mouse model has high reproductive performance with a short generation time and larger litter size. Various genetically identical strains can be manufactured via inbreeding with special reference to increase their number and explore inbreeding-related disorders.
- They share an accelerated lifespan
The role of the mouse model is significant due to its overall extended lifespan of 12-18 months with a very short generation time of 10 weeks and a gestation length of 21 days. Mouse colonies can be abducted very easily within a short period.
