Researchers have developed a novel approach using knowledge graphs and Large Language Models (LLMs) to predict the effects of gene knockout perturbations on transcriptomic gene expression. Their simplest model, a K-nearest neighbor approach leveraging biological knowledge graphs, achieved competitive performance, outperforming most methods on out-of-distribution predictions. Further enhancements using LLMs trained via reinforcement learning for predictive accuracy matched state-of-the-art results, demonstrating the potential of knowledge graphs as model priors and LLMs as adaptable tools for complex biological response prediction.
