How can you use “myocyte” in a sentence? Here are some example sentences to help you improve your vocabulary:
The furazolidone-induced turkey model is a well characterizedexperimental model of dilated cardiomyopathy with features verysimilar to those found in human heart failure [ 19 20 21 22 ] .Decreased contractile function (reduced fractional shortening ofthe left ventricle) and morphological changes (increased heart volumes,left ventricular dilatation, and myocyte hypertrophy) are characteristic featuresof this model [ 21 22 ] .
These observations,and the results from several animal models, demonstrate that apoptoticcells are present in failing hearts, suggesting that apoptosis mightbe a mechanism involved, at least in part, in the progression ofheart failure and the reduction of myocyte mass.
The initial increase in circulating norepinephrineis thought to maintain cardiac function through inotropic mechanisms.However, a direct cardiac myocyte toxicity from norepinephrine iswell recognized [ 6 7 ] . Furthermore, pressure-overloadand stretch associated release of angiotensin II has been shownto induce myocyte apoptosis [ 8 9 10 ] .In an elegant paper by Telger et al.
Recent studies have proposed that myocyte loss incardiomyopathy can occur by apoptosis without an inflammatory response [reviewedin [ 1 2 3 ] ]. In heart failure,growth stimulation initially occurs as a compensatory effort tomeet chronically altered hemodynamic demands and is mediated by systemicand/or local up-regulation of mediators of adrenergic pathways andby various cytokines [ 4 5 ] . However, cytokinescan be directly toxic to cardiac myocytes and result in increasedapoptotic cell death [ 3 6 ] . Local up-regulationof angiotensin II induces immediate-early genes, which may leadto increased protein synthesis and myocardial hypertrophy or, alternatively,may up-regulate expression of apoptotic proteins (such as p53) incardiac myocytes.
The development of well-characterized cardiac progenitor cells offers the promise of using real genetic-based approaches to rapidly define the complex pathways that guide cardiac contractility, excitability, and lineage diversification into atrial, ventricular, and conduction system myocyte cell lineages.
