Epigenetic changes and cardiac reconstruction are among the most important adaptations in endurance training. The aim of this study was to investigate the gene expression of histone deacetylase-4 and myocyte enhancer factor-2c (MEF-2c) in male rats in interaction with exhaustive swimming. 12 male Wistar rats (mean age: 7±1 weeks, weight 275±25 gr) were randomly divided into two groups (each group 6 subjects): control and training. After performing the exhaustive swimming for 3 hours per session and 5 days per week for 10 weeks, their left ventricle was isolated; then the gene expression were investigated by Real Time-PCR. Data were analyzed by independent t test and the significance level was P≤0.05. The results showed that after 10 weeks of exhaustive swimming, the HDAC4 gene significantly increased (P=0.02), but MEF-2c gene significantly decreased (P=0.001) compared with the control group. Therefore, 10 weeks of exhaustive swimming increased gene expression of HDAC-4 and consequently reduced gene expression of MEF-2c by an increase in the activity of transcription factors attached to HDAC-4.
