WebAbstract. Recent investigations of titin anchorage and elasticity have been supplemented with in vitro expression studies on isolated domains of titin and nebulin. These have yielded new insights into the molecular basis of the functions of these proteins in muscle. The characterization of a cellular (non-muscle) isoform of titin has extended ... WebPrevious evidence has shown that titin, a muscle cell protein, is increased in the urine of patients with DMD, suggesting its usefulness as a DMD biomarker. Here, we demonstrated that the elevated titin in urine is directly associated with the lack of dystrophin and urine titin responses to drug treatment. We performed a drug intervention study ...
