1. AI-assisted personalised cancer targeting
   An Australian tech entrepreneur used AI tools (including ChatGPT-style systems) to help analyse DNA sequencing data from his dog Rosie’s tumour. The aim was to identify neoantigens—unique mutation-driven markers that could be targeted by the immune system—by sifting through the tumour’s genetic “spelling mistakes”.

2. Creation of a bespoke mRNA cancer vaccine
   Researchers at the University of New South Wales used the AI-informed shortlist of tumour mutations to design a personalised vaccine. Using mRNA vaccine technology, they produced a custom treatment intended to train Rosie’s immune system to recognise and attack her cancer cells.

3. Early, uncertain results and broader implications
   Rosie, an eight-year-old Rosie (dog) with aggressive cancer, reportedly showed tumour shrinkage and improved wellbeing after treatment. However, experts stress this is a single, uncontrolled case: while promising, it is not proof of effectiveness. The case highlights both the potential of AI-accelerated personalised medicine and the need for rigorous testing, safety standards, and ethical oversight in such experimental therapies.
