An Expression Makes a World of Difference

At Syros, we are pioneering a new area of medicine focused on controlling the expression of genes. The genes expressed - turned on, off, up or down - in any given cell determine its type and function, and when wrong genes are expressed at the wrong time or in the wrong amounts, it can lead to disease. By creating medicines to control the expression of genes, we aim to make a profound difference in the lives of patients and their families. Join us in understanding the coordinated expression of the Syros team in fulfilling our mission.

We Understand How the Expression of Genes Is Controlled

Regulatory regions of the genome control the expression of genes, turning them on, off, up or down, like genomic dimmer switches and determining how a cell behaves, whether it is a skin cell or a lung cell, whether it is normal or diseased. Because gene expression is fundamental to the function of all cells, alterations in these regulatory regions contribute to virtually all diseases. But until recently, scientists lacked the tools to study these regulatory regions, rendering them poorly understood and largely unexploited for drug discovery and development.

We have built the leading platform dedicated to the regulatory genome to systematically and efficiently identify disease-causing alterations in gene expression and develop medicines that control the expression of genes with the aim of providing a profound benefit for patients with diseases that have largely eluded other genomics-based approaches.
