How ChatGPT and AlphaFold Helped Shrink a Terminal Tumour by 75%

Discover how a Sydney data engineer used DeepMind's AlphaFold and ChatGPT to design a world-first personalised mRNA cancer vaccine for his dog.

In this episode, we deconstruct the "n-of-1" case of Rosie the Staffy, whose terminal mast cell tumours were treated using a bespoke vaccine designed by a non-biologist. We move past the headlines to look at the actual technical workflow: from genomic sequencing and protein-structure prediction to the synthesis of mRNA nanoparticles. This analysis explores the democratization of drug discovery and the role of AI as a scientific project manager in modern oncology.

Key Takeaways

• How AlphaFold 3D protein modeling identifies neoantigens for vaccine design.

• The role of LLMs in navigating complex scientific infrastructures and genomic pipelines.

• The regulatory and ethical challenges of "rapid-response" personalised medicine.
