-Two proteins that make up part of the cardiac cell contractile apparatus troponins I and T have become the markers of choice for detecting MI. Cardiac troponin levels become elevated in serum at about the same time as CK- but they remain elevated for a longer period. ST-segment elevation is thought to represent acute cell injury and ischemia.

Nov 01 1982 · Changes in the contractile apparatus of denervated rat soleus muscles were investigated during the course of reinnervation. As observed earlier in the course of denervation atrophy the ratio of myosin to actin filaments decreases because myosin filaments disappear faster than actin filaments (Jakubiec-Puka et al. 1981 a).
