title: [Expression of energy metabolism-related genes in myocardial tissues of rats with diabetic cardiomyopathy].
abstract: OBJECTIVE
  To study the pathogenesis of diabetic cardiomyopathy using DNA microarray.
  
  
  METHODS
  Experimental rats were grouped into a diabetic cardiomyopathy and a normal control group. The cDNA probes were prepared by labeling the mRNA extracted from normal tissue and tissue of diabetic cardiomyopathy with Cy3-dUTP and Cy5-dUTP respectively through reverse transcription. DNA microarray were constructed by spotting PCR products of 4 000 rat cDNAs onto a specially treated glass slides, and were then hybridized against the cDNA probes followed by fluorescent signals scanning.
  
  
  RESULTS
  The expression of energy metabolism-related genes were lower in the tissues of diabetic cardiomyopathy than in normal tissue.
  
  
  CONCLUSIONS
  The energy metabolism disorder may play an important role in the pathogenesis of diabetic cardiomyopathy.
