DeepREAD — это инновационная ИИ-модель от Shape Therapeutics, созданная для точного редактирования РНК. Она объединяет генеративное глубокое обучение и высокопроизводительный скрининг для проектирования специфических направляющих РНК (gRNA). Это решение открывает новые горизонты в разработке генной терапии, минимизируя побочные эффекты при лечении заболеваний.
Adenosine Deaminase Acting on RNA (ADAR) converts adenosine to inosine within certain double-stranded RNA structures. However, ADAR’s promiscuous editing and poorly understood specificity hinder therapeutic applications. We present an integrated approach combining high-throughput screening (HTS) with generative deep learning to rapidly engineer efficient and specific guide RNAs (gRNAs) to direct ADAR’s activity to any target. Our HTS quantified ADAR-mediated editing across millions of unique gRNA sequences and structures, identifying key determinants of editing outcomes. We leveraged these data to develop DeepREAD (Deep learning for RNA Editing by ADAR Design), a diffusion-based model that elucidates complex design rules to generate novel gRNAs outperforming existing design heuristics. DeepREAD’s gRNAs achieve highly efficient and specific editing, including challenging multi-site edits. We demonstrate DeepREAD’s therapeutic potential by designing gRNAs targeting the MECP2R168X mutation associated with Rett syndrome, achieving both allelic specificity and species cross-reactivity. This approach significantly accelerates the development of ADAR-based RNA therapeutics for diverse genetic diseases.
