High-throughput screening of a cancer cell panel represents a pivotal instrument in the armamentarium of drug discovery and development. The sensitivity profiles of these cell lines serve as a cornerstone for the refinement of in vivo model systems and for the stratification of patient cohorts in clinical trials. Werner Syndrome RecQ Helicase (WRN), a member of the RecQ helicase family, is instrumental in the preservation of genomic integrity. Its multifaceted role encompasses DNA repair, replication, recombination, and telomere maintenance. WRN has garnered significant attention as a potential therapeutic nexus in oncology, particularly within the context of tumors exhibiting microsatellite instability (MSI). The synthetic lethality between WRN and MSI has been the subject of intensive research, demonstrating that WRN inhibition is selectively toxic to cancer cells harboring a high microsatellite instability (MSI-H) phenotype, which is a characteristic observed across a spectrum of malignancies, including colorectal, endometrial, and gastric cancers.
