Monkey-based research on human disease: the implications of genetic differences

Area of Science:

• Biomedical Research
• Comparative Genomics
• Translational Medicine

Background:

• Assertions of scientific validity for using monkeys in human disease research often cite 90-93% genetic similarity.
• However, critical analyses reveal significant physiological and molecular disparities between species.

Purpose of the Study:

• To critically evaluate the scientific validity of using monkeys as models for human diseases.
• To analyze the physiological and molecular differences that impact the translatability of monkey research to human health outcomes.

Main Methods:

• Comparative genomics and molecular biology analyses.
• Review of existing research data on drug trials, infectious diseases (SIV/HIV), and neurological disorders (Alzheimer's, Parkinson's, stroke).

Main Results:

• Genetic similarity does not ensure sufficient physiological similarity for reliable disease modeling.
• Significant molecular differences exist in gene expression, protein function, and chromatin structure.
• Monkey data show poor translation to human clinical practice, exemplified by drug trial failures and differing disease pathologies.

Conclusions:

• The extrapolation of biomedical data from monkeys to humans is highly unreliable.
• The scientific value of using monkeys for human disease research is questionable.
• Alternative research methods offer greater potential for advancing human health.
