Fig. 8: The effect of fecal microbiota transplantation from abdominal LIPUS treated mice on the MSTN/AKT/mTOR signaling pathway in hindlimb unloaded mice.

A The protein level of MSTN in gastrocnemius muscle. B The protein level of ActRIIB in gastrocnemius muscle. C The protein level of AKT in gastrocnemius muscle. D The protein level of mTOR in gastrocnemius muscle. The data were expressed as mean ± SD, ∗p < 0.05 and ∗∗p < 0.01.
