Fig 1. MR16-1 administration protocol.

Eleven-week-old C57BL/6J male mice were administered MR16-1 via intraperitoneal injection and subjected to tail suspension. The mice were subjected to two days of tail suspension to examine atrogene expression in the soleus muscles (A, n = 7–8), and to two weeks of tail suspension to measure soleus muscle weight and CSA (B, n = 5). The arrowheads indicate MR16-1 administration and its amount.
