Previous studies successfully demonstrated that transgenic models expressing Cyclin D2 under the transcriptional regulation of the alpha-cardiac myosin heavy chain (MHC) promoter showed a better recovery after Myocardial Infarction (MI), with an increase in the number of living cardiomyocytes (Hassink et al., 2008). The gene discussed is CCND2; the disease is myocardial infarction.
