EIF4G1 and cystic fibrosis: Interestingly, the levels of hepatic eIF4G1 were lower in SAAR rats when compared to CF rats38, but we found a slight increase in skeletal muscle eIF4G1 protein levels in young male SAAR mice compared to young CF mice, but this difference was not statistically significant, and the same trend was observed in C2C12 myotubes exposed to SAAR.
