Western blotting analysis of GDF15 in the skeletal muscle (SM-GDF15). (A) Representative immunoblotting image of GDF15 and GAPDH in the skeletal muscle. (B) Relative protein expression of GDF15 in the SM from 23 healthy subjects (HS) and 16 patients with lower limb mobility impairment (LLMI). (C) Relative protein expression of GDF15 in the SM from 10 HS <40 years (<40) and 13 HS >70 years (>70). (D) Relative protein expression of GDF15 in the SM from 7 LLMI <40 and 9 LLMI >70. The bars represent mean ± SD. The quantification was performed using Fiji software and normalized to GAPDH expression. Student’s t test was applied.
