Abstract:
AIM: Centrifuge training can improve forward acceleration (+Gz) endurance. This study was to analyzed the gene expression of rat heart affected by centrifuge, and to research the molecular mechanism of improving +Gz endurance by centrifuge training. METHODS: Differential expressed genes between high+Gz endurance (+16Gz) rats, of test group after trained 12 d and control were screened using suppression subtractive hybridization (SSH) and dot blot hybridization. The obtained expressed sequence tags (ESTs)were used as probes to perform RNA slot hybridization with heart total RNA isolated from each gruop of centrifuge training and high+Gz endurance and low+Gz endurance (+12Gz) rats, respectively. The positive ESTs were sequenced and analyzed using BLAST(nr) at NCBI.RESULTS: Three down-regulated ESTs were obtained from heart samples, all of them are new, and their expression levels were decreasing during centrifuge training. CONCLUSION: Centrifuge training can significantly affect the special gene expressions of rat heart, and the expression changes of these genes may be ralated to the mechainism that +Gz endurance can be improved by centrifuge training.
