About Us

SENISCA is an award-winning biotech from the University of Exeter, focused on modulating RNA biology to treat age-related disease.

SENISCA targets the process of cellular ageing (senescence) via the development of RNA senotherapeutics which specifically target the causative molecular mechanisms that drive senescence.

Age-related disease is caused by the failure in basic cell health mechanisms, collectively known as the hallmarks of ageing. 15+ years of world-leading research by SENISCA's founders led to the identification of a novel hallmark of ageing, dysregulated RNA splicing, a fundamental contributor to cellular senescence and ageing. We are leveraging this proprietary knowledge to develop senotherapeutics that specifically reverse senescence for the treatment of age-related disease.

Scientific Approach

A major cause of age-related diseases is the accumulation of senescent cells in ageing tissues and organs. In vivo, the removal of senescent cells has been shown to promote tissue ‘rejuvenation’ and improve organ function. At SENISCA, we have discovered a novel, officially-recognised, and druggable means to reprogram senescent cells through modulation of dysregulated RNA splicing.

When genes are switched on, messenger RNA (mRNA) is produced, which contains the precise instructions or blueprint which is translated into the proteins required by cells. Depending on the needs of the cell, most genes can produce more than one type of mRNA message (called isoforms), in a process termed ‘alternative splicing.’ The balance of mRNA isoforms generated from each gene is critical and determines the way cells adapt and respond to their environment. This ability to ‘fine tune’ gene outputs is vital for long-term health. The choice of which isoforms are produced is made by a set of regulatory proteins collectively termed splicing factors.

SENISCA’s founders have discovered that levels of splicing factors change during ageing, reducing the cells’ ability to conduct this ‘fine tuning’ of gene expression. This is a fundamental reason why cells become senescent. Compromised molecular resilience is a major cause of the ill health and frailty that accompanies ageing. SENISCA’s foundational data demonstrate that restoration of splicing factors to the levels seen in younger cells can effectively turn back the ageing clock in senescent cells, bringing about an attenuation of their deleterious functions.

At SENISCA, we are developing oligonucleotide-based therapeutic approaches to reset splicing factor levels and reprogram senescent cells. Our unique understanding of the molecular basis of rejuvenation enables us to develop new treatments, targeting the causes and not simply the consequences of age-related disease.
