The protein JUN plays a key role in restraining the cancer growth-promoting proteins YAP and TAZ, thereby helping to prevent uncontrolled cancer growth. The findings have now been published in the EMBO Journal under the title „A non-canonical repressor function of JUN restrains the activity of YAP and the growth of liver cancer“. The study was led by Dr. Björn von Eyss, who heads the research group „Transcriptional Control of Tissue Homeostasis“ at the Leibniz Institute on Aging – Fritz Lipmann Institute in Jena.
