Researchers Developed a Genetic Algorithm Operating Within Cellular Structures, Mimicking Artificial Intelligence Biologically
In a groundbreaking development, researchers from the University of Sydney have unveiled PROTEUS, a biological artificial intelligence system designed to mimic natural selection within mammalian cells. This innovative technology promises to accelerate drug discovery and advance gene therapies by harnessing the power of directed evolution.
### Key Features of PROTEUS
1. **Directed Evolution in Mammalian Cells**: By enabling directed evolution within mammalian cells, PROTEUS allows for the rapid creation and adaptation of molecules with new functions, significantly reducing the time required compared to traditional methods.
2. **Enhanced Molecule Design**: PROTEUS can explore millions of potential sequences to design molecules that are highly adapted to solve specific biological problems. This capability is crucial for developing proteins and other molecules that are finely tuned to function effectively in the human body.
3. **Gene Editing Enhancements**: Integrating with gene editing technologies like CRISPR, PROTEUS can enhance their effectiveness, generating new molecules that are highly compatible with human biology, leading to more precise and efficient gene therapies.
4. **Customized Proteins and Nanobodies**: The system has been used to develop improved versions of proteins that can be more easily regulated by drugs and nanobodies that detect DNA damage, a process critical in cancer development.
### Applications in Gene Therapies and Disease-Fighting Proteins
- **Gene Therapies**: PROTEUS can be used to create new gene therapies by evolving molecules that are highly compatible with human cells, potentially leading to more effective treatments for genetic disorders.
- **Disease-Fighting Proteins**: The system can design proteins that are specifically tailored to combat diseases, such as cancer, by targeting unique biological markers or mechanisms involved in disease progression.
The PROTEUS system, with its ability to rapidly evolve customized proteins and molecules, positions itself as a critical tool in the quest for more effective treatments against a wide range of diseases. The system operates with chimeric virus-like vesicles, which are harmless packages of genetic material.
In cells exposed to cisplatin, a chemotherapy drug that damages DNA, the improved biosensor lit up inside the nucleus, forming tiny glowing foci. This demonstrates the system's potential to detect and combat DNA damage, a crucial step in cancer development.
If the technology can be adapted to work in human cell types beyond hamster cells (BHK-21), it could provide researchers with tissue-specific or even disease-specific evolution environments. This would further enhance the system's ability to develop targeted therapies for various diseases.
PROTEUS tests millions of never-before-seen mutations in real, living cells, much like how generative AI tools explore possibilities to find useful answers. The current mutation bias in PROTEUS favors certain genetic changes, and more work is needed to evolve biomolecules with completely unbiased diversity.
The system has been likened to a sort of biological AI, offering a revolutionary platform for accelerating drug discovery and developing advanced gene therapies by leveraging directed evolution in mammalian cells. With its potential to rapidly evolve customized proteins and molecules, PROTEUS is poised to make a significant impact in the field of medicine.
