a HEK293 cells were transfected overexpression of FBXO30. Thirty-six hours after transfection, BRE-luciferase activity was measured after treatments with BMP-2 (100 ng/ml) and/or RA (1 μM) for 12 h. Data are mean ± s.d. (n = 3). b HEK293 cells were transfected with the siRNA-FBXO30. Thirty-six hours after transfection, BRE-luciferase activity was measured after treatments with BMP-2 (100 ng/ml) and/or RA (1 μM) for 12 h. Data are mean ± s.d. (n = 3). c, d Overexpression of FBXO30 or siRNA-FBXO30 transfected in HEK293 cells as indicated. Thirty-six hours after transfection, cells were stimulated with BMP-2 and/or RA for 12 h before harvesting. Western blot was performed to examine the pSmad1/5 and total Smad1/5 levels in whole-cell lysates. Aliquots of total lysates were immunoblotted to indicate antibody. Numbers at the bottom were generated by quantification (Image J) of the pSmad1/5 signal normalized to the Smad1/5 signal. e siRNA-FBXO30 or siRNA-normal transfected in HEK293 cells as indicated. Thirty-six hours after transfection, cells were stimulated with BMP-2 and/or RA for 12 h before harvesting. Direct visualization or indirect immunofluorescence was performed. Scale bars, 22 μm
