RICTOR and cystic fibrosis: CF epithelial cells have an increased expression of both mTOR and Rictor (Reilly et al., 2017), which could explain the disturbed morphology and loss of cortical rim F‐actin in epithelial cells (Abbattiscianni et al., 2016; Castellani et al., 2017) and possibly also in HLMVEC treated with GlyH‐101 observed in the present study; however, this warrants further investigation.
