Cells were collected and the total protein and nuclear protein were extracted according to the instructions (Beyotime, P0013B and P0027, respectively). The protein concentration was measured using a BCA protein determination reagent kit (Beyotime, P0011). Western blotting was performed as previously described50 (link). The primary antibodies included anti-GAPDH (YM1038) purchased from Immunoway; anti-LNGFR (ab8874) and anti-RunX2 (ab23981) purchased from Abcam; and anti-β-catenin (8480) and anti-Lamin B1 (13435) purchased from CST.
