Non-Genetically Engineering Model Development Services
Developing animal models has played a vital role in enhancing our comprehension of intricate rare diseases. Our organization specializes in delivering top-notch services for the creation of NON-GEMs, providing diverse model choices customized to meet specific research needs related to rare diseases. By employing non-genetic engineering methodologies, our company possesses the capability to develop NON-GEMs that faithfully replicate rare diseases, thereby expediting the advancement of targeted therapies and investigation into disease pathogenesis.
Introduction to Non-Genetically Engineering Models (NON-GEMs)
Non-genetically engineering models (NON-GEMs) are a category of animal models that aim to create simplified yet comparable representations of human physiology and diseases without genetic modification. The construction methods of NON-GEMs can be divided into physical, chemical, and biological methods.
- Physical factors involve subjecting animals to mechanical injury, surgery, radiation, or other physical means.
- Chemical factors encompass the use of chemical carcinogens (such as alkylating agents, nitrosamines, and aromatic amines), chemical poisoning, or excessive nutrient exposure to induce disease in animals.
- Biological factors involve the introduction of bacteria, microorganisms, parasites, or biotoxins (such as aflatoxin) that act as pathogens in animals.

Rare diseases pose unique challenges due to their limited prevalence and lack of understanding. Through physical, chemical, and biological techniques, researchers can create animal models that exhibit characteristics of rare diseases, including metabolic disorders, neurodegenerative conditions, and lysosomal storage diseases. These models serve as valuable tools for investigating rare disease progression and identifying novel biomarkers. The following are examples of animal models of Parkinson's disease constructed through non-genetic engineering techniques:
Table 1 Non-genetically engineering models (NON-GEMs) of Parkinson's disease. (Su, Cheng-Fu, et al., 2021)
| Model | Mechanism | Behavior Deterioration | Major Usage of the Model | Disadvantages |
|---|---|---|---|---|
| MPTP-induced | A reduction of striatal DA and TH | Dyspraxia | To generate irreversible and severe motor abnormalities | No loss of neurons from locus coeruleus; lack of age-dependent, slow progressive lesion development |
| Rotenone-induced | Suppresses mitochondrial complex I | Impaired motor activity | To trigger deterioration of nigrostriatal DA as well as aggregated proteins like α-synuclein | Age-independent lesions |
| 6-OHDA-induced | Pro-oxidant properties, inhibits complex I activity | Rotational behavior | To induce motor impairment of limbs | Does not cross the BBB |
| Paraquat- and maneb-induced | Accelerates α-synuclein fibril formation | Impaired motor activity | To produce neuronal damage and a Parkinsonian-like syndrome | The dopaminergic toxicity is not selective |
