OBJECTIVE: To evaluate the effect of aerobic exercise on genome expression in human skeletal muscle. METHODS: Six healthy sedentary elderly men aged (66+9) years were selected from military cadre retirement centers and after exercise. Testing indices included height, weight, vital capacity, step index and maximal oxygen uptake. Needle biopsies were obtained from the skeletal muscle before and after the last training. Total RNA extracted from the samples was hybridized to Affymetrix U 133A platform, the gene expression datum was analyzed.RESULTS: Aerobic exercise was shown to improve cardiorespiratory function and reduce body fat of elder subjects. It could alter the genome expression in human skeletal muscle, the number of genes that passed filtering criteria was 725. The most differently expressed genes (n=20) were investigated in this study, in which there were 3 upregulated and 17 downregulated. According to gene function annotations, the differential genes were classified into 8 categories which concerned cellular component and biological process, Kyoto Encyclopedia of Genes and Genomes (KEGG) searching showed 4 genes' metabolism pathway. CONCLUSION: Systematic aerobic exercise upregulates expression of enzyme genes concerning tricarboxylic acid cycle, and downregulates expression of genes conceming muscle protein synthesis and sphingolipid. It is suggested that aerobic exercise is good to protect human nerves' integrity, exerts positive action on anti-aging and accelerate the aerobic metabolism of lipid materials in vivo.

Aim To investigate the protective effects of nicorandil, glutamine and metoprolol used in single and combination on the antiapoptosis ability of cardio-cytes and the expression of HSP70 after myocardial is-chemia/reperfusion injury in rats. Methods Male Wistar rats were divided randomly into seven groups:( 1 ) Sham group:in which the coronary artery was not roped;(2) I/R group:in which only 30 min ischemia and 120 min reperfusion of LAD was executed; ( 3 ) Nicorandil group; ( 4 ) Glutamine group; ( 5 ) Meto-prolol group; ( 6 ) Nic + Glu + Met ( NGM ) group;(7) low dose of Nic+Glu+Met ( NGML) group. In the pharmacological precondition groups, correspond-ing drugs were administered 30 min before I/R proto-col, and the initial drug dose in each group was 1 mg ·kg-1 . Myocardial apoptotic rates were measured with TUNEL ( terminal dexynucleotidyl transferase-mediated dUTP nick end labeling) , and the expression of apop-tosis related proteins-Bcl-2/Bax and protective pro-tein-HSP70 was detected by Western blot. ResultsIn I/R group, the apoptotic rate in ischemic region was very high ( 36.9% ± 10.3%) , and Bcl-2/Bax was very low ( 0.14 ±0.08 ) . Compared with I/R group, the apoptotic rate of pharmacological precondition groups was decreased significantly ( P <0.01 ) , and the ratio of Bcl-2 to Bax was raised ( P<0.01 ) . Com-pared with Sham group, the expression of HSP70 in-creased significantly ( P<0.01 ) in I/R group. Com-pared with IR group, the expression of HSP70 of phar-macological precondition groups was elevated ( P <0.01 ) , and the expression in NGM group was higher than in the single drug group ( P<0.01 ) . Conclusion Compared with single therapy after I/R in rat, the combination therapy of nicorandil, glutamine, meto-prolol can decrease the apoptotic rate, and the expres-sion of apoptosis related proteins is developed. In the mean time, the expression of protective protein HSP70 is elevated.
