Executive Industry Relevance

Genome-wide measurement of transcript decay rates in proliferating and quiescent human fibroblasts enables biopharma teams to distinguish regulatory mechanisms driving gene expression changes beyond transcriptional control. This approach supports mechanistic de-risking and enhances predictive confidence in target validation by clarifying whether observed gene expression differences are due to altered mRNA stability or transcriptional activity. Integrating transcript decay profiling at early discovery inflection points informs portfolio triage and prioritization of disease-relevant targets.
