The quest for innovative cancer therapies has taken a significant leap forward with the introduction of Cell2Sentence-Scale 27B (C2S-Scale), a groundbreaking 27 billion parameter foundation model. Developed in collaboration with Yale University, this AI model has successfully identified a novel hypothesis about cancer cellular behavior, which has been confirmed through experimental validation. This breakthrough has the potential to revolutionize cancer immunotherapy by making “cold” tumors more visible to the immune system.
C2S-Scale is built on the Gemma family of open models, representing a new frontier in single-cell analysis. The model’s capabilities were put to the test by designing a dual-context virtual screen to find a conditional amplifier that would boost the immune signal in a specific “immune-context-positive” environment. The results were striking, with the model predicting a significant increase in antigen presentation when the kinase CK2 inhibitor silmitasertib (CX-4945) was applied in this setting. This prediction was subsequently confirmed in lab tests, demonstrating a roughly 50% increase in antigen presentation.
This achievement marks a milestone for AI in science, showcasing the potential of large-scale models to generate biologically grounded hypotheses and accelerate the discovery of new therapies. The C2S-Scale model and its resources are now available to the research community, inviting scientists to explore and build upon this work. As researchers continue to push the boundaries of AI in biotechnology, we can expect to see more innovative solutions emerge, transforming the way we approach cancer treatment and beyond.
