Lawrence Lum, Ph.D.
Virginia Murchison Linthicum Scholar in Medical Research

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Scarring of the adult heart due to excessive fibrotic responses is common after a heart attack, or following radiation therapy for the treatment of certain cancers. We have identified an anti-cancer agent currently in clinical development called WNT-974 that decreases fibrotic responses and improves heart function following myocardial infarction in mice. This unexpected observation was the outcome of a study focused on identifying unwanted adult tissue toxicities associated with this class of chemicals.
MedicalResearch.com: What should readers take away from your report?
Response: Anti-cancer agents in development such as WNT-974 that disable the production of secreted Wnt proteins should also be evaluated for their potential utility in regenerative medicine.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Response: Other adult tissues in addition to the heart may also see improvements in regeneration following transient suppression of Wnt protein production as a consequence of mitigated fibrotic responses. These possibilities should be further investigated.
