The chicken gene encoding cardiac troponin T (cTNT) is expressed in both cardiac and skeletal muscle during early embryonic development, but is specifically repressed in skeletal muscle during fetal development. To determine if the cis-acting sequences governing transcription of a single gene in these two related cell types are the same, we have transfected promoter/upstream segments of the cTN...

Transgenic mice expressing an allele of cardiac troponin T (cTnT) with a COOH-terminal truncation (cTnT(trunc)) exhibit severe diastolic and mild systolic dysfunction. We tested the hypothesis that contractile dysfunction in myocardium expressing low levels of cTnT(trunc) (i.e., <5%) is due to slowed cross-bridge kinetics and reduced thin filament activation as a consequence of reduced cross-br...

* B K U U E o the Editor: Post-exercise release of cardiac troponin (cTn)T and TnI has been previously reported after prolonged bouts of exercise 1). However, this release has only been observed in a limited umber of subjects (2). It is unclear whether post-exercise release f cTn represents necrosis of cardiac myocytes, and thus irreversble damage, or a transient and reversible change in membra...

patients and methods this cross-sectional study included a total of 120 adult predialysis ckd patients. forty patients were allocated in each predialysis ckd group of stages 3, 4, and 5. serum ctnt and hs-crp, plasma nt-probnp, and single spot urine albumin creatinine ratio (acr) were measured. ultrasonographic examination of carotid artery was done with 7.5 mhz linear probe in b mode ultrasono...

OBJECTIVES We prospectively evaluated the relation between cardiac troponin T (cTnT) level, the presence and severity of coronary artery disease (CAD) and long-term prognosis in patients with chest pain but no ischemic electrocardiographic (ECG) changes who had short-term observation. BACKGROUND Cardiac TnT is a powerful predictor of future myocardial infarction (MI) and death in patients wit...

question in the cTnT-ESRD debate is the prognostic importance of this biochemical abnormality, and particularly whether these patients require some modification of their treatment. We have followed 81 hemodialysis patients over a 20-month period and have found no increase in mortality in those with increased cTnT (7 deaths from 43 patients) compared with those with cTnT within reference values ...

Introduction. Respiratory distress are very common in Very-low-birth-weight (VLBW) infants and Myocardial injury may play a role in the disease outcome. Cardiac troponin T (cTnT) is the most useful marker of injury in adult population, but has not been extensively studied in this population. Aim. To study the role of cTnT in VLBW infants and its association with clinical outcomes. Methods. All ...

BACKGROUND Increased C-reactive protein (CRP) is an important prognostic indicator for early risk stratification in patients with an acute coronary syndrome (ACS), independent of, and in combination with, increased cardiac troponin T (cTnT). However, increases in both cTnT and CRP also occur secondary to myocardial damage. METHODS AND RESULTS In 156 consecutive patients, early release kinetic...

ported criteria of S/LC -cTnI 6.7 or S/LC -cTnT 5.3 (1, 2 ). Taken together, 55 (15.9%) of the 345 samples were positive for autoantibodies to cardiac troponin I or T isoforms. In these positive samples, 10.9% (6 of 55) were positive for both autoantibodies. The odds of being positive for both autoantibodies increased in the presence of either species; in samples positive for autoantibodies to ...
