CTGF IS HIGHLY EXPRESSED IN BAV AND TAV TISSUES WITH ANEURYSM. CTGF UP-REGULATES ECM BIOSYNTHESIS AND IS INVOLVED IN THE
PHENOTYPIC CHANGE OF AORTIC VSMC IN VITRO.
VSMC PHENOTYPE AND CTGF EXPRESSION AT CV AND CX SIDE OF ASCENDING AORTA
CTGF INDUCES SYNTHETIC MARKERS OF PHENOTYPE IN VSMC ISOLATED FROM CONTROL AND ANEURISMAL AORTA
CONCLUSION AND FUTURE DIRECTIONS
Different stress conditions influence VSMC phenotype in BAV aorta. Characterize CTGF as a regulator of VSMC activation and ECM remodeling could serve as a risk stratification tool for BAV- and
TAV-associated aortopathies.
