Cardiac troponin T and fast skeletal muscle denervation in ageing
BACKGROUND Ageing skeletal muscle undergoes chronic denervation, and the neuromuscular junction (NMJ), the key structure that connects motor neuron nerves with muscle cells, shows increased defects with ageing. Previous studies in various species have shown that with ageing, type II fast-twitch skeletal muscle fibres show more atrophy and NMJ deterioration than type I slow-twitch fibres. Howeve...
متن کاملPhosphorylase kinase phosphorylation of skeletal-muscle troponin T.
Rabbit skeletal-muscle troponin T was phosphorylated by a standard preparation of phosphorylase kinase [Cohen (1973) Eur. J. Biochem. 34, 1--14] and by fractions obtained after chromatography of phosphorylase kinase on phosphocellulose. The original preparation of phosphorylase kinase phosphorylated at least two sites, one of which was serine-1. The second and probably the third sites were pres...
متن کاملCardiac troponin I, cardiac troponin T, and creatine kinase MB in dialysis patients without ischemic heart disease: evidence of cardiac troponin T expression in skeletal muscle.
Serum cardiac troponin T (cTnT) concentrations are frequently increased in chronic dialysis patients as measured by the first-generation ELISA immunoassay, as is creatine kinase (CK) MB mass in the absence of acute ischemic heart disease. We designed this study to compare four serum markers of myocardial injury [CK-MB mass, first-generation ELISA cTnT, second-generation Enzymun cTnT, and cardia...
متن کاملTroponin subunit stoichiometry and content in rabbit skeletal muscle and myofibrils.
The quantity and molar ratio of the three troponin subunits to actin were determined in rabbit psoas muscle, muscle homogenates (800 X g pellet), and purified myofibrils. Proteins were separated by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. The quantities of the separated proteins were determined directly from the gel slices by amino acid analysis after correc...
متن کاملEvaluation of Troponin-T level in Neonate with Mechanical Ventilation
Introduction: Troponin- T is the best biological marker of heart injuries, that isn’t affected by sex, age, birth weight and gestational age. Myocardial damage in infancy is a risk factor eventual cardiac disease. This study carried out for cardiac evaluation of neonates with mechanical ventilation by Troponin T. Methods: This case-control study carried out on 60 infants that were admitte...
