Project description
The quest to control alternative splicing
Alternative splicing (AS) is the important process allowing the production of different messenger RNAs and proteins from a single gene in complex organisms, including humans. AS alterations contribute to diseases such as cancer and neurodegeneration. While AS-targeting drugs have recently provided the first therapy for a common genetic disorder, much remains to be learnt about the mechanisms controlling splicing and their modulation by small molecules. Funded by the European Research Council, the multidisciplinary UNLEASH project aims to understand how splice site selection is regulated and whether it can be specifically modulated by small molecules. The project will generate many new tool compounds to study gene function and potentially help develop new therapeutics.
Objective
Alternative splicing (AS) of mRNA precursors plays important roles in tissue-specific gene regulation and biological regulatory mechanisms, as it can radically alter protein expression, cell phenotypes and physiological responses. Altered splicing also contributes to disease mechanisms, ranging from neurodegeneration to cancer. Drugs modulating AS have recently provided the first therapy for Spinal Muscular Atrophy, a common genetic disorder, illustrating the huge potential for treating many other diseases of unmet need, if only we understood the mechanisms controlling splice site selection and how to regulate them with small molecules. Unfortunately, despite decades of research, a comprehensive understanding of the mechanisms that control specificity of AS is lacking. This gap in basic knowledge prevents opportunities to harness splicing modulators as tools to study gene function, novel therapeutics or other biotech applications. This Project addresses head-on the major technical challenges that have limited progress in the AS field. Building on extensive preliminary data, we will use a multidisciplinary approach that combines chemical, structural, cellular, systems biology and machine learning to characterize mechanisms of splice site selection and identify targets for modulating these mechanisms using tool compounds. The outcomes will define key regulatory sequences, splicing factors and molecular interactions involved, thereby illuminating how the splicing machinery efficiently accommodates, yet also discriminates between, a wide range of splice site sequences. This will enable future applications harnessing splice site selection. Our primary goal is to answer the central question, ‘Is it generally possible to modulate splicing with high specificity using small molecules?’ Success will transform our basic understanding of human gene expression and unleash major opportunities for Pharma to develop new therapeutics.
