Project description:Objective: To evaluate gene expression profiles in multiple sclerosis (MS) patients who improved their fatigue status after a program of physical exercise and to compare them with healthy controls (HC). Methods: A prospective longitudinal study was conducted. Gene expression in whole blood was profiled at baseline in 7 healthy controls and also in 7 fatigued-MS patients. Patients underwent a physical exercise program for 6 months, and their fatigue status and gene expression profiles were again analyzed at the end of this program. Results: MS patients showed a significant activation of genes participating in the systemic interferon response in comparison with healthy controls. Fatigue improved at the end of the physical activity program, and, in parallel, systemic activation of interferon related genes disappeared. Conclusions: Fatigue improvement following an exercise program is associated to down modulation of interferon activity at the systemic level in MS patients. Our results provide a biological basis for the observed benefit of physical exercise in MS.

Project description:One inevitable consequence of the effect of age on our bodies is the graduated deterioration of physical function and exercise capacity, driven, in part by the adverse effect of age on muscle tissue. Our primary purpose was to determine the relationship between patterns of gene expression in skeletal muscle and loss of physical function. We hypothesized that some genes that change expression with age would correlate with functional decline, or conversely with preservation of function. Male C57Bl/6 mice were randomly selected from large cohorts [RNA isolated from: adults (6-7 months old, n=9), older (24-25 months old, n=9), and elderly (28+ months of age, n=9)} that were tested for physical ability using a comprehensive functional assessment battery [CFAB, a composite scoring system: comprised of the rotarod (overall motor function), grip strength (fore-limb strength), inverted cling (4-limb strength/endurance), voluntary wheel running (activity rate/volitional exercise), and treadmill tests (endurance)]. We extracted RNA from the tibialis anterior muscles, ran RNAseq to examine the transcriptome using an Illumina NextSeq 550, comparing adults (n=7) to older (n=7) and elderly mice (n=9). Age resulted in gene expression differences of 1.5 log2 fold change or greater (p<0.01) in 46 genes in the older mice and in 252 genes in the elderly (both compared to adults). Current ongoing work is examining the physiological relevance of these genes to age-related loss of physical function. We are in the process of using linear regression to determine which of the genes with age-related changes in expression are associated (R>0.5 and p<0.05) with functional status as measured by CFAB.

Project description:Human aging is associated with skeletal muscle atrophy and functional impairment (sarcopenia). Multiple lines of evidence suggest that mitochondrial dysfunction is a major contributor to sarcopenia. We evaluated whether healthy aging was associated with a transcriptional profile reflecting mitochondrial impairment and whether resistance exercise could reverse this signature to that approximating a younger physiological age. Skeletal muscle biopsies from healthy older (N = 25) and younger (N = 26) adult men and women were compared using gene expression profiling, and a subset of these were related to measurements of muscle strength. 14 of the older adults had muscle samples taken before and after a six-month resistance exercise-training program. Before exercise training, older adults were 59% weaker than younger, but after six months of training in older adults, strength improved significantly (P<0.001) such that they were only 38% lower than young adults. As a consequence of age, we found 596 genes differentially expressed using a false discovery rate cut-off of 5%. Prior to the exercise training, the transcriptome profile showed a dramatic enrichment of genes associated with mitochondrial function with age. However, following exercise training the transcriptional signature of aging was markedly reversed back to that of younger levels for most genes that were affected by both age and exercise. We conclude that healthy older adults show evidence of mitochondrial impairment and muscle weakness, but that this can be partially reversed at the phenotypic level, and substantially reversed at the transcriptome level, following six months of resistance exercise training.

Project description:The skeletal muscle system plays an important role in the independence of older adults. In this study we examine differences in the skeletal muscle transcriptome between healthy young and older subjects and (pre‐)frail older adults. Additionally, we examine the effect of resistance‐type exercise training on the muscle transcriptome in healthy older subjects and (pre‐)frail older adults. Baseline transcriptome profiles were measured in muscle biopsies collected from 53 young, 73 healthy older subjects, and 61 frail older subjects. Follow‐up samples from these frail older subjects (31 samples) and healthy older subjects (41 samples) were collected after 6 months of progressive resistance‐type exercise training. Frail older subjects trained twice per week and the healthy older subjects trained three times per week. At baseline genes related to mitochondrial function and energy metabolism were differentially expressed between older and young subjects, as well as between healthy and frail older subjects. Three hundred seven genes were differentially expressed after training in both groups. Training affected expression levels of genes related to extracellular matrix, glucose metabolism, and vascularization. Expression of genes that were modulated by exercise training was indicative of muscle strength at baseline. Genes that strongly correlated with strength belonged to the protocadherin gamma gene cluster (r = −0.73). Our data suggest significant remaining plasticity of ageing skeletal muscle to adapt to resistance‐type exercise training. Some age‐related changes in skeletal muscle gene expression appear to be partially reversed by prolonged resistance‐type exercise training. The protocadherin gamma gene cluster may be related to muscle denervation and re‐innervation in ageing muscle.

Project description:Age-related declines in cardiorespiratory fitness and physical function are mitigated by regular endurance exercise in older adults. This may be due, in part, to changes in the transcriptional program of skeletal muscle following repeated bouts of exercise. However, the impact of chronic exercise training on the transcriptional response to an acute bout of endurance exercise has not been clearly determined. Here, we characterized baseline differences in muscle transcriptome and exercise-induced response in older adults who were active/endurance trained or sedentary. RNA-sequencing was performed on vastus lateralis biopsy specimens obtained before, immediately after, and 3 h following a bout of endurance exercise (40 min of cycling at 60%–70% of heart rate reserve). Using a recently developed bioinformatics approach, we found that transcript signatures related to type I myofibers, mitochondria, and endothelial cells were higher in active/endurance-trained adults and were associated with key phenotypic features including V̇o2peak, ATPmax, and muscle fiber proportion. Immune cell signatures were elevated in the sedentary group and linked to visceral and intermuscular adipose tissue mass. Following acute exercise, we observed distinct temporal transcriptional signatures that were largely similar among groups. Enrichment analysis revealed catabolic processes were uniquely enriched in the sedentary group at the 3-h postexercise timepoint. In summary, this study revealed key transcriptional signatures that distinguished active and sedentary adults, which were associated with difference in oxidative capacity and depot-specific adiposity. The acute response signatures were consistent with beneficial effects of endurance exercise to improve muscle health in older adults irrespective of exercise history and adiposity.

Project description:This randomized controlled trial is a multicentre study designed to explore the effects of preoperative exercise on physical fitness, postoperative complications, recovery, and health-related quality of life in older individuals at risk scheduled to undergo colorectal cancer surgery. The hypothesis is that older patients with low preoperative physical capacity will benefit from preoperative exercise in terms of lower risk for postoperative complications and improved recovery after surgery.

Project description:Parkinson’s disease (PD) is a common neurodegenerative disease with movement and balance impairments. It has been shown that physical exercise could ameliorate balance impairments and improve life quality of PD patients. However, the related mechanisms of benefit of exercise are still poorly understood, especially in the peripheral immune system. The present study aimed to utilize sensitive high-throughput transcriptome analyses to investigate potentially favorable effects of physical exercise in leukocytes.

Project description:The primary aim of this study is to establish if it is possible for patients who have undergone major body surgery to complete a home based exercise training program and complete the assessments required to measure physical and cognitive function. If the investigators can establish that it is feasible to complete the training and test’s then further research can follow using these methods to determine whether it is possible to improve the physical function of older patients undergoing major abdominal surgery in the period following surgery by using a simple exercise regimen that can be carried out at home. By targeting physical function in this way the investigators hope to determine if it is a method for improving frailty and well being. In turn it may also have a positive impact on health service provision.

Project description:This phase I trial tests the feasibility, acceptability, and preliminary effectiveness of online dietary and resistance training to improve physical function in older (greater than or equal to 65-years old) cancer survivors. Declines in adequate protein and calorie intake results in faster loss of muscle mass and physical functioning in older adults. A novel approach to improving physical function in older cancer survivors (OCS) is to utilize online, tailored education and counseling from registered dietitians and exercise scientists, to improve dietary intake (protein intake, diet quality) and participation in resistance exercise. The purpose of this study is to help researchers learn whether an online dietary and resistance training intervention improves diet, exercise, physical function, and health outcomes in OCS.
