Scientists uncover exciting lead into premature aging and heart disease
Date:4/30/2012

actually expected that knocking out Sun1 in these mouse models would worsen their conditions and cause them to die faster but surprisingly we observed the opposite. This is the first time that Sun1 protein has been implicated in diseases linked to Lamin A and it is exciting how basic research has led to a discovery that can potentially have significant impact on us," said Rafidah Abdul Mutalif, who is pursuing her PhD at IMB and one of the main authors of this paper.

Prof. Colin Stewart, Principle Investigator at IMB, said, "Notably, the heart muscle of the mice was restored to near normal function and cardiac function improved when the levels of SUN1 were reduced. Mutations in Lamin A are frequently reported as a cause of heart disease and especially within a group of hereditary cardiomyopathies. This opens up a possibility that from these observations, reduction in SUN1 maybe of therapeutic use for other forms of heart disease. We are very excited about this discovery and look forward to further pursuing this lead which could potentially lead to development of new treatments for heart diseases."
