Project description:Analysis of impact of successful combined aerobic and strength training intervention of CAD patients on lymphomonocyte gene expression. The purpose of this study was to identify the most up/down-regulated gene sets related to the training to increase our knowledge on the mechanisms mediating the exercise-induced effects.

Project description:Human subjects were randomized for treatment with a GnRH-analogue, Goserelin, which suppresses endogenous testosterone or placebo for 12 weeks. Strength training was performed during the last 8 weeks. The suppression of testosterone resulted in an attenuation of the normal muscle adaptation to strength training (increased muscle mass and strength). To identify molecular signals involved in the response to testosterone levels, biopsies were obtained 4 hours after the last training session and gene expression compared with Affymetrix 3' microarrays. This timepoint should capture goserelin effect on both constitutive expression, training induced changes as well as acute exercise induced (4 hours) differences in mRNA levels. Four subject from the placebo group and five subjects from the Goserelin group were compared. Total RNA from vastus lateralis mmuscle biopsies were purified and analyzed on Affymetrix HG-U133 Plus 2.0 arrays.

Project description:This study examined the effectiveness, suitability, and safety of a mixed interval-type aerobic and strength training program (MIAST) on physical fitness in patients with stable coronary artery disease (CAD) without history of myocardial infarction (MI). Twenty-three patients with stable CAD were randomly assigned to a MIAST (n = 12; mean age 58.6 years) or control (n = 11; 63.3 years) group. The MIAST group participated in the progressive training program twice a week for 21 weeks. Peak oxygen uptake (VO2peak), workload, and exercise time were measured as were maximal muscle strength, serum lipids, glucose concentration, and the cross-sectional area (CSA) of knee extensors. The safety and suitability of the program were assessed by wireless electrocardiogram (ECG) monitoring and exercise diaries. VO2peak (6.9%; P < 0.05) and exercise time (11.2%; P < 0.05) improved significantly after 12 weeks of training in the MIAST group compared to the control group. Muscle strength (19.9%; P < 0.05) and CSA (2.2%; P < 0.05) increased, and serum lipids and blood glucose tended to decrease after the training. The successful training program (increase in maximal oxygen uptake) increased the gene expression of oxygen metabolism and decreased the gene expression of inflammation pathways in lymphomonocytes. The MIAST program, including interval-type aerobic and strength training, was safe, did not cause any adverse effects, and led to significant improvements in physical fitness in patients with stable CAD.

Project description:Myotonic dystrophy type 1 (DM1), the most common form of adult-onset muscular dystrophy, is caused by a CTG expansion resulting in significant transcriptomic dysregulation that leads to muscle weakness and wasting. While strength training is clinically beneficial in DM1, molecular effects had not been studied. To determine whether training rescued transcriptomic defects, RNA-sequencing was performed on vastus lateralis samples from nine male DM1 patients before and after a 12-week strength training program and six male controls who did not undergo training. Differential gene expression and alternative splicing analysis were correlated with the one-repetition maximum strength evaluation method (leg extension, leg press, hip abduction, and squat). While training program-induced improvements in splicing were similar among most individuals, rescued splicing events varied considerably between individuals. Gene expression improvements were highly varied between individuals with the percentage of differentially expressed genes rescued after training strongly correlated with strength improvements. Evaluating transcriptome changes individually revealed responses to the training not evident from grouped analysis, likely due to disease heterogeneity and individual exercise response differences. Our analyses indicate that transcriptomic changes are associated with clinical outcomes in DM1 patients undergoing training and these changes are often specific to the individual and should be analyzed accordingly.

Project description:Proteomic characterization of skeletal muscle biopsies collected from the vastus lateralis of 44 male and female human subjects. Research subjects were divided in three different groups based on their individual exercise backgrounds and physical performance testing: 1) endurance trained (males; ME, n = 9 and females; FE, n = 9, with at least 15 years’ of regular training experience), 2) strength-trained males (MS, n = 9, with at least 15 years’ of regular training experience), and 3) age-matched healthy untrained controls (males, MC, n = 9 and females FC, n = 8, with a self-reported history of <2 exercise bouts per week over the past 15 years).

Project description:In this study, the primary objective was to characterise the impact of regular post-exercise (20 strength training sessions across 10 weeks) cold-water immersion (CWI) on DNA methhylation. Secondary to this, the effect of regular post-exercise CWI on strength gains and post-exercise soreness was investigated. We used microarrays to detail the global effects of CWI on DNA methylation in vastus lateralis muscle tissue.

Project description:Apolipoprotein C-III was recently acknowledged as a prognostic marker for cardiovascular risk. High levels of Apo-CIII strongly correlate with hypertriglyceridemia and are associated with atherosclerosis and coronary heart disease (CAD). Aim of the present research was to study the plasma proteome profiles of stable CAD patients characterized by different levels of total Apo-CIII. Two subgroups of CAD patients with divergent concentrations (under and upper the median concentration of the population distribution=10mg/dL) of total circulating Apo C-III were examined using a shotgun proteomic approach. 180 plasma proteins of CAD patients were quantified and the data were analyzed by bioinformatic tools and multivariate statistics. The fold change analysis and the Partial Least Square Discriminant Analysis showed a clear separation of the two groups. The dynamic processes that involve Apo C-III concentration in blood and its relation with all other plasma proteins were considered. Lipoproteins (Apo C-II and Apo E), retinol-binding protein 4 and vitronectin were up-regulated in patients with high Apo C-III, while alpha 1-antitrypsin was down-regulated. In this pilot study, the different expression of plasma proteins through the entire range of concentrations of Apo C-III was defined, suggesting possible new players involved in the APO C-III-associated process of arterial damage
