Second, the cardioprotective effects were compared between the two naked DNA constructs, expressing a single (HGF<jats:sub>728<\/jats:sub>) or both isoforms (HGF<jats:sub>728<\/jats:sub> and HGF<jats:sub>723<\/jats:sub>) of HGF, in the rat ischemic heart disease model. The ischemic injury to the rat heart was created by ischemia\u2013reperfusion in the anterior descending artery. The respective naked DNA constructs were injected into the anterior wall of the rat heart with the ischemia\u2013reperfusion injury. Cardiac function, capillary density and anti\u2010fibrotic activity were compared between the two naked DNA constructs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The intramyocardial administration of pCK\u2010HGF\u2010X7 resulted in transient and localized HGF expression for 3\u2009weeks. At its peak, approximately 678\u2009pg (per mg of tissue protein) of HGF was produced in the injected heart without an increase of HGF protein level in other tissues, and serum. pCK\u2010HGF\u2010X7 more efficiently improved the left ventricular ejection fraction and the systolic anterior wall thickness, increased the capillary density, and inhibited myocardial fibrosis, in a statistically significant manner, compared to the identical vector encoding HGF<jats:sub>728<\/jats:sub> only.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These results demonstrate that transfer of the genomic\u2010cDNA hybrid expressing both isoforms of the HGF gene might provide higher therapeutic effects than the cDNA sequence producing HGF<jats:sub>728<\/jats:sub> alone in the treatment of ischemic heart disease.
