SPARC leads to the phosphorylation of SMAD2. 7 / 7
1 | 4 2

reach
"In vitro recombinant SPARC increases Smad 2 phosphorylation, indicating that SPARC activates TGF-beta pathway."

reach
"SPARC also stimulated Smad2 phosphorylation in MB114 endothelial cells but had no effect on bone morphogenetic protein regulated Smad1 phosphorylation in either Mv1Lu or MB114 cells."

"treatment of Mv1Lu cells with SPARC or SPARC-EC stimulated Smad2 phosphorylation"

sparser
"It was reported that SPARC stimulated Smad2 phosphorylation and Smad2/3 nuclear translation in lung epithelial cells [ xref ]."

reach
"Our data indicate that SPARC modulates the TGF-beta1-dependent phosphorylation of Smad-2 in primary mesangial cells derived from wild-type and SPARC-null mice."

reach
"These results were concordant with experiments in vitro, which showed that addition of recombinant SPARC increased Smad2 phosphorylation at baseline as well as after stimulation with TGF-beta1 (XREF_FIG)."

sparser
"Furthermore, Schiemann et al. [ xref ] found that SPARC-induced SMAD2 phosphorylation in endothelial and epithelial cells, an effect that was blocked with a neutralizing TGF- β antibody."
