ABSTRACT: In this study, we proved the exercise-induced promotion of osteogenic differentiation and inhibition of adipogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) through establishing exercise animal model by treadmill running experiment. miRNA sequencing analysis identified 16 upregulated and 2 downregulated miRNAs in exercise group.

Project description:Using Affymetrix GeneChip® Rat Genome 230 2.0 Array chip to screen the effect of Uphill and Downhill treadmill exercise on the key genes that affect bone mass in the peripheral blood mononuclear cells (PBMCs) of young male rats. Thirty-six male Sprague-Dawley rats were randomly assigned to a control group and both running groups of uphill and downhill (n = 12). Bone mineral density (BMD), bone mineral content (BMC) and bone microstructure of the femur were measured. PBMCs were extracted and the gene expression profile of mRNA detected.Gene Ontology and KEGG pathway analysis were used.The results showed exercise mainly activated the biological processes and cellular pathways involved in immune, inflammation and osteoclast differentiation.
Project description:Seventy two rats were randomized to twelve independent groups of rats (n = 6 in all groups) where half of the rats were chosen for training (treadmill exercise training 1.5 hour 5 days a week, in 1, 4, 24, 48 days and for 4 and 8 weeks) or sedentary (no training) as described in detail by Wisloff et al. (Intensity-controlled treadmill running in rats: VO(2 max) and cardiac hypertrophy. Am J Physiol Heart Circ Physiol. 2001 Mar;280(3):H1301-10.) or Kemi et al.(Aerobic fitness is associated with cardiomyocyte contractile capacity and endothelial function in exercise training and detraining. Circulation. 2004 Jun 15;109(23):2897-904. Epub 2004 Jun 1.). The rats were scarified one hour after training (1, 4, 24 and 48 days) or 24 hours after training (4 and 8 weeks). Biopsies form left ventricle was taken form all rats and stored on -80°C for preparation of RNA. The same procedures were performed for the control/sedentary rats which were sacrificed at the same time as the exercised rats.

Project description:Voluntary running exercise after focal cerebral ischemia promotes functional recovery and prevents the ischemia-induced dendritic spine loss in the peri-infarct motor cortex layer 5. Neuronal morphology is affected by the perineuronal environmental change. Glia exert crucial roles in the formation of perineuronal environment, and exercise-induced changes of glial phenotype are expected. Here, we demonstrated that voluntary running exercise increased the population of newborn astrocytes in the acute phase after cerebral ischemia at late phase. Transcriptome analysis detected 10 upregulated genes and 70 downregulated genes by exercise in the ipsilateral cortex astrocytes. Gene cluster downregulated by exercise were significantly associated with neuronal morphology. The expression of Lipocalin 2, a factor of decreasing dendritic spines, tended to be decreased in the postischemic astrocytes by exercise. Our results suggest that exercise modifies the phenotype of postischemic astrocytes, which relate to the exercise-induced amelioration of postischemic dendritic spine loss.
Project description:Gene expression profiles in the tarsal joints of DBA/1 mice whit collagen-induced arthritis that performed treadmill exercise in the post-arthritic phase vs. those who were not exercised were compared. Exercise induced the upregulation of inflammatory genes and signaling pathways.
