Article Title: Differential Smad2/3 linker phosphorylation is a crosstalk mechanism of Rho/ROCK and canonical TGF-β3 signaling in tenogenic differentiation
doi: 10.1038/s41598-024-60717-z
Figure Lengend Snippet: Gene expression and Western blot of Smad2/3. Cells cultured as monolayer or on collagen matrix were incubated with 10 ng/ml TGF-β3 and/or 10 μM Y-27632. ( A ) Box plots represent the relative gene expression of Smad2/3. Asterisks mark differences between the stimulation groups with p < 0.05. Letters mark differences with p < 0.05 between collagen matrix and monolayer within same stimulation groups or in comparison to monolayer control (n = 4). ( B ) Representative western blot result of carboxy-terminal phosphorylation at Ser 465/467 after 24 h stimulation. ( C ) Quantitative analysis of carboxy-terminal phosphorylation at Ser 465/467 at 60 min, 12 h (n = 3) and 24 h (n = 5). Box plots represent the ratio of P-Smad to Smad2/3 and dots the values of the different donors.
Article Snippet: After blocking with 5% milk or BSA, depending on the respective antibody, in a Tris–buffered saline 0.5% Tween (TBST) solution overnight at 4 °C, membranes were stained with antibodies against total-smad 2/3 (1:1000, D7G7, #8685, Cell Signaling Technology), p-smad2 S245/250/255 (1:1000, #3104, Cell Signaling Technology), p-smad S465/467 (1:1000, E8F3R, #18338, Cell Signaling Technology) or p-smad3 S204 (1:500, A24906, Bioworld Technology) for 1 h. Then membranes were washed with TBST three times, incubated with an anti-rabbit HRP-conjugated secondary antibody (1:200, #7074, Cell Signaling Technology) for 1 h and washed again four times.
