The upregulated phosphoproteins in the CF compared with the MF group included glycogen synthase kinase-3 beta (GSK3β), thyroid hormone receptor interactor 10 (TRIP10), epidermal growth factor receptor pathway substrate 8 (EPS8), phosphoglucomutase-1 protein (PGM1), and eukaryotic translation initiation factor 4 B (EIF4B). Here, EIF4B is linked to cystic fibrosis.
