Total cell lysates were prepared as previously described [24] (link). The protein concentration was determined using Bio-Rad protein assay reagent. A total of 70 µg of proteins was resolved on 10% Bis–Tris gels and transferred to nitrocellulose membranes. The protein levels of target genes were detected using specific primary antibodies and IRDye secondary antibodies on Odyssey Fluorescence Imaging System (LI-COR Biosciences, USA). The density of the immunoblots was analyzed using Odyssey V3.0 software and normalized with β-Actin.
