  RECS1 is one of the mechanical stress responsive genes and functions as a negative regulator of matrix metalloprotease 9 (MMP-9). RECS1 deficient mice are prone to aortic dilation and cystic medial degeneration (CMD) when the mice ages (older than 14 months). Aortic dilation and CMD are frequently encountered pathological findings in aortic aneurysms as well as in normal aging aorta. This strain is useful for study of the function of RECS1 gene and as a mouse model for aortic dilation and CMD.
