Silencing protein production inside cells

Small interfering RNA (siRNA) are double-stranded RNA molecules that offer new opportunities for therapeutic intervention because they act inside the cell to reduce protein expression. They do this by targeting RNA to prevent the production of disease-associated proteins.1-3

Through our collaboration with Silence Therapeutics, we aim to develop novel, targeted treatments to address significant unmet need for the treatment of Cardiovascular, Renal, Metabolic and Respiratory diseases.

Harnessing Silence’s established siRNA platform, the collaboration will identify and progress liver-based targets, as well as develop new delivery approaches for targeting other tissues such as the heart, lungs and kidneys. Targeted delivery to these other tissues represents a new opportunity to treat Cardiovascular, Renal, Metabolic and Respiratory diseases.

The collaboration with Silence adds an exciting modality, siRNA, to our toolbox to help us develop novel therapeutics and address unmet medical needs.
