LC3 and p62 mRNA expression in the spinal cord and the skeletal muscle. (a) The transcript levels in the spinal cord of males (black bars) and females (grey bars) from mice at P60, P90, and P120 are shown. Relative expression values are females compared with males (set at 1) at each age. (b) The transcript levels in skeletal muscles of male (black bars) and female (grey bars) mice at P40, P60, P90, and P120 are shown as in (a). Each data point represents the mean ± SEM of twelve mice. Asterisks denote a student -test value <0.05 (*), <0.01 (**), and <0.001 (***).
