Protein extracts were prepared from frontal and parietal bones of one-month-old mice after cutting out the sutures. The bone tissues were immersed into liquid nitrogen, grinded to powder, and then lysed using NP40 lysis buffer (PH 8.0 Tris-HCl 20mM, NaCl 137mM, 1% NP40, 10% Glycerol, Na3VO4 1mM). Western blotting was performed and analyzed similar to our previous studies [39 (link)–41 (link)]. The following primary antibodies were used: rabbit anti-RBCC1 (FIP200) antibody (proteintech, 17250-1-AP), rabbit anti-P62 antibody (Enzolife science BML-PW9860-0100), mouse anti-LC3 antibody (Nanotools, NT-0231-100), mouse anti-vinculin antibody (Sigma-aldrich V4505), and rabbit anti-ATG5 antibody (CST, #13007).
