Finally, Axin2 expression is decreased and Wnt/β-catenin signalling is increased in myxomatous mitral valves in a murine model of Marfan syndrome, supporting the importance of Wnt/β-catenin signalling in the development of MVD.
The combination of BRAF(V600E) mutation in the setting of altered TGF-β signaling and weak connective tissue integrity associated with MFS may cooperate and possibly be responsible to form this unique villous morphology with epithelial-to-mesenchymal transition and invasive growth.
In vivo noninvasive biomechanical analyses with CST offer a new, non-invasive method to identify pathologic corneal deformation responses in adults with MFS.
Laminin γ-1 was decreased in MV and increased in M. In conclusion, similarities and differences in oxidative stress in the different aortopathies studied including pathologies with aneurysms were found with alterations in SOD, CAT, GPx, GST, and eNOS activity that modify subendothelial basement membrane proteins.
Homocysteinuria arising due to cystathionine beta-synthase (CBS) deficiency is an autosomal recessive disorder of methionine metabolism that produces increased levels of urinary homocysteine and methionine It manifests itself in vascular, central nervous system, cutaneous, and connective tissue disturbances and phenotypically resembles Marfan's syndrome.

Conversely, the synthesis and expression of CD109, a TGFβ co-receptor used to facilitate the diagnosis of high-grade MFS diagnosis, was maintained constant until high cancer cell line passages.
Immunohistochemistry showed increased expression of TGFbeta1 to 3, hyaluronan, and CD34-positive microcapillaries in MFS aneurysm compared with control.
Western blot showed increased expression of TGFbeta1 to 3 in MFS but no change in expression of CD44, MT1-MMP, or beta-3 integrin compared with controls.
APPROACH AND RESULTS: <i>Cdh5-Cre</i> and <i>Sm22-Cre</i> transgenic mice were used to inactivate the At1ar-coding gene (<i>Agt1ar</i>) in either intimal or medial cells of both wild type and Marfan syndrome mice, respectively.
Cultured MFS-VSMC depicted marked phenotype changes vs. wild-type (WT) VSMC, with overexpressed cell proliferation markers but either lower (calponin-1) or higher (SM alpha-actin and SM22) differentiation marker expression.
A substitution at a non-glycine position in the triple-helical domain of pro alpha 2(I) collagen chains present in an individual with a variant of the Marfan syndrome.
The inheritance of restriction fragment length polymorphisms for two fibrillar collagen genes (COL1A2 and COL3A1) has been studied in a large Marfan syndrome kindred.
