BMP signaling agonist sb4 (0.05 μM-1 μM; 24 hours) induces phosphorylated SMAD-1/5/9 in a dose-dependent manner in PRECs cells under serum-starved conitions. BMP signaling agonist sb4 (1 μM; 0-60 mins) enhances the efficacy of signaling at each concentration of rhBMP4 tested. This effect is most pronounced at low concentrations of rhBMP4, whereby sb4 increases BRE-luc expression 2-fold at 0.4 ng/ml of rhBMP4. Western Blot Analysis Cell Line: Primary mouse kidney epithelial cells (PRECs) Concentration: 0.05 μM-1 μM Incubation Time: 24 hours Result: Incresed p-SMAD-1/5/9 abundance in PRECs. Western Blot Analysis Cell Line: BRE-Luc cells Concentration: 1 μM Incubation Time: 0min, 5 mins, 15 mins, 30 mins, 45 mins, 60 mins Result: Acted to stabilize p-SMAD-1/5/9 to enhance the transcriptional response.
