Long noncoding RNAs (lncRNAs) modulate gene expression at the epigenetic, transcriptional, and posttranscriptional levels. Dysregulation of the lncRNA known as myocardial infarction-associated transcript (MIAT) has been associated with myocardial infarction. Chagas disease causes a severe inflammatory dilated chronic cardiomyopathy (CCC). We investigated the role of MIAT in CCC. A whole-transcriptome analysis of heart biopsy specimens and formalin-fixed, paraffin-embedded samples revealed that MIAT was overexpressed in patients with CCC, compared with subjects with noninflammatory dilated cardiomyopathy and controls. These results were confirmed in a mouse model. Results suggest that MIAT is a specific biomarker of CCC.
长链非编码RNA（lncRNAs）在表观遗传、转录和转录后水平调节基因表达。一种名为心肌梗死相关转录本（MIAT）的lncRNA失调与心肌梗死有关。恰加斯病会引发严重的炎症性扩张型慢性心肌病（CCC）。我们研究了MIAT在CCC中的作用。对心脏活检标本以及福尔马林固定、石蜡包埋样本的全转录组分析显示，与非炎症性扩张型心肌病患者和对照组相比，MIAT在CCC患者中过表达。这些结果在小鼠模型中得到了证实。结果表明，MIAT是CCC的一种特异性生物标志物。
