Smad3 mutation
WebbThe patient's SMAD3 mutation (c.200 T >G; p.I67S), when expressed from plasmid vectors in HEK293 cells, showed reduced phosphorylation and transcription factor activity compared to normal control and SMAD3 (p.S264Y), a gain-of- function mutation, somatic mosaicism of which causes melorheostosis. WebbMutations of SMAD3 cause FTAAD in 2% of cases and are also causative of Marfan syndrome and Loeys–Dietz syndrome . This is supported by studies of SMAD3 knockout mice, which experience greatly accelerated development of aortic …

Webb1 dec. 2024 · Somatic gain-of-function SMAD3 mutations cause melorheostosis, a sporadic sclerotic dysostosis with distinct local excessive bone formation. Such activating SMAD3 mutations increase TGF-β signaling inhibiting osteoblast proliferation and stimulating osteoblast differentiation. Webb1 juni 1998 · Smad3 and Smad4 bind to the TGFβ-inducible CAGA box. ( A) An EMSA was performed using a 33 P-labelled probe containing the CAGA sequence and nuclear extract from HepG2 cells induced for 30 min by TGFβ or not induced. Bands corresponding to specific TGFβ-induced complexes are indicated.
