Detection of RNA Editing Sites by GPT Fine-tuning

Accurately predicting RNA editing sites is crucial for leveraging endogenous base editing technologies for therapeutic applications. This study introduces a novel methodology leveraging advanced AI techniques, specifically OpenAI's GPT-3.5, to predict both the occurrence and efficiency of RNA editing by base editors such as ADAR enzymes. By fine-tuning GPT models on extensive datasets of RNA sequences and secondary structures, we observe improvements in predictive accuracy, with our approach outperforming existing approaches. Our approach involves framing the problem in two distinct ways: as a generation problem, predicting new edited structures, and as a classification problem, determining if specific sites are edited. We also implement robust data augmentation strategies and threshold adjustments to optimize the model's performance. Our findings highlight the transformative potential of GPT in solving complex biological problems, providing a robust framework for future genetic interventions.The sources of this work are available at our repository: https://doi.org/10.5281/zenodo.13835229
