CFTR regulates PIP5KA expression and PI(4,5)P2 concentration. (A) C2C12 myotubes were treated with CFTR inh172, and the concentration of PI(4,5)P2 was measured by dot blot. **P < 0.01 compared with control (n = 3). (B) The concentration of PI(4,5)P2 in mice FDB muscle was measured by dot blot. **P < 0.01 compared with control (n = 3). (C) C2C12 myotubes were treated with CFTR inh172, and the protein level of PIP5KA was measured by western blot. **P < 0.01 compared with control (n = 3). (D) The protein level of PIP5KA in mice FDB muscle was measured by western blot. **P < 0.01 compared with control (n = 3).
