Casting and tenotomy induced different rates of proteolytic cleavage. A: total cathepsin activity in tenotomy- and casting-induced atrophy was measured in total muscle extracts. Error bars represent SD; n = 8. B: proteasome activity in tenotomy- and casting-induced atrophy was measured in total muscle extracts. Error bars represent SD; n = 8. C: MMP2 activity in tenotomy- and casting-induced atrophy was measured in total muscle extracts. Error bars represent standard error; n = 10. *P < 1 × 10−7 and #P < 0.001 compared with the respective contralateral control limbs.
