troponin


Also found in: Medical, Encyclopedia, Wikipedia.

tro·po·nin

 (trō′pə-nĭn, trŏp′ə-)
n.
A calcium-regulated protein, composed of three subunits, that is found in skeletal and cardiac muscle and regulates contraction by interacting with tropomyosin to control the binding of myosin to actin. Blood troponin levels are a biomarker for muscle damage, as in myocardial infarction.

troponin

(ˈtræʊpənɪn)
n
a protein in muscle tissue that with tropomyosin is involved in the controlling of muscle contraction

tro•po•nin

(ˈtroʊ pə nɪn, ˈtrɒp ə-)

n.
a protein of muscle tissue that binds calcium ions and is involved in contraction.

Madam, cardiac troponin is the diagnostic mainstay for cardiomyocyte damage.
The more damage there is to the heart, the greater will be the amount of troponin in the blood.
Summary: A new study has shown that sitting was more strongly associated with unhealthy levels of troponin, proteins produced by cardiac-muscle cells when they are hurt or dying
Experts from James Cook University Hospital, in Middlesbrough, wanted to test whether troponin - a protein found to be released into the bloodstream during a heart attack - levels could predict long-term survival after surgery.
Twenty years ago in Clinical Chemistry, cardiac troponin I (cTnI) (3) autoantibodies to the stable portion of cTnI near the carboxyterminal end of the molecule were first identified as an etiology for false-negative cTnI results (1).
4] In the last decade, much interest has been drawn to the importance of serum troponin in acute stroke.
The use of the protein troponin I as a diagnostic for cardiac events is well established.
An abnormal troponin T level of 14 ng/L or higher, as measured using a high-sensitivity assay, doubles the risk of cardiovascular (CV) events and death among patients who have stable ischemic heart disease and type 2 diabetes, according to a report.
Troponin consists of three components or subunits, (9,10) tropomyosin-binding subunit (Tn-T), (11) inhibitory subunit (Tn-I), (12) and calcium-binding subunit (Tn-C).
