title: Microarray profiling of long non-coding RNA (lncRNA) associated with hypertrophic cardiomyopathy.
abstract: BACKGROUND
  Hypertrophic cardiomyopathy (HCM) is an inherited disorder with around 1400 known mutations; however the molecular pathways leading from genotype to phenotype are not fully understood. LncRNAs, which account for approximately 98 % of human genome, are becoming increasingly interesting with regard to various diseases. However, changes in the expression of regulatory lncRNAs in HCM have not yet been reported. To identify myocardial lncRNAs involved in HCM and characterize their roles in HCM pathogenesis.
  
  
  METHODS
  Myocardial tissues were obtained from 7 HCM patients and 5 healthy individuals, and lncRNA and mRNA expression profiles were analyzed using the Arraystar human lncRNA microarray. Real-time PCR was conducted to validate the expression pattern of lncRNA and mRNA. Gene ontology (GO) enrichment and KEGG analysis of mRNAs was conducted to identify the related biological modules and pathologic pathways.
  
  
  RESULTS
  Approximately 1426 lncRNAs (965 up-regulated and 461 down-regulated) and 1715 mRNAs (896 up-regulated and 819 down-regulated) were aberrantly expressed in HCM patients with fold change > 2.0. GO analysis indicated that these lncRNAs-coexpressed mRNAs were targeted to translational process. Pathway analysis indicated that lncRNAs-coexpressed mRNAs were mostly enriched in ribosome and oxidative phosphorylation.
  
  
  CONCLUSIONS
  LncRNAs are involved in the pathogenesis of HCM through the modulation of multiple pathogenetic pathways.
