(Submitter supplied) We sought to ascertain the time-course of transcriptional events that occur in human skeletal muscle at the outset of resistance exercise (RE) training in RE naïve individuals, and determine if the magnitude of any response was associated with exercise induced muscle damage. Sixteen RE naïve males were recruited, 8 underwent 2 sessions of 5x30 maximum, isokinetic knee extensions (180°.s-1) separated by 48 hrs. more...

(Submitter supplied) 10 male subjects performed ~45 min one-legged cycling and 4 x 7 maximal concentric-eccentric knee extensions for each leg 15 min later. Thus, one limb performed aerobic and resistance exercise (AE+RE), while the opposing leg did resistance exercise only (RE). Biopsies were obtained from m. vastus lateralis of each leg 3 h after the resistance exercise bout. Gene expression analysis was carried out on the Affymetrix HuGene-2.1-st platform.

(Submitter supplied) Global microarray (HG U133 Plus 2.0) was used to investigate the effects of resistance exercise and resistance training on the skeletal muscle transcriptome profile of 28 young and old adults. Vastus lateralis muscle biopsies were obtained pre and 4hrs post resistance exercise in the beginning (untrained state) and at the end (trained state) of a 12 wk progressive resistance training program.

(Submitter supplied) While acute aerobic and resistance exercise stimulate a number of shared genes, each exercsie mode stimlutes a number of uniquely responsive genes, thus highlighting that different forms of exercise facilitate distinct molecular responses in skeletal muscle.

(Submitter supplied) Skeletal muscle adapts to resistance exercise (RE) performance acutely and chronically. An important regulatory step of muscle adaptation to RE is gene expression. Microarray analysis can be used as an exploratory method to investigate how genes and gene clusters are modulated acutely and chronically by RE. The purpose of the present study was to investigate the effect of training status in the basal (rested) and pre- to 24h post-RE on the global transcriptome in vastus lateralis muscle biopsies of young men. more...

(Submitter supplied) The functions of the Hsp70 genes were studied using a line of D. melanogaster with knockout of six these genes out of thirteen. Namely, effect of knockout of Hsp70 genes on negative geotaxis climbing (locomotor) speed and the ability to adapt to climbing training (0.5-1.5 h/day, 7 days/week, 19 days) were examined. Seven- and 23-day-old Hsp70– flies demonstrated a comparable reduction (2-fold) in locomotor speed and widespread changes in leg skeletal muscle transcriptome (RNA-seq), compared to w1118 flies. more...

(Submitter supplied) We sought to determine the skeletal muscle genome-wide DNA methylation and mRNA respons-es to one bout of lower-load (LL) versus higher-load (HL) resistance exercise. Trained col-lege-aged males (n=11, 23±4 years old, 4±3 years self-reported training) performed LL or HL bouts to failure separated by one week. The HL bout (i.e., 80 Fail) consisted of four sets of back squats and four sets of leg extensions to failure using 80% of participants estimated one-repetition maximum (i.e., est. more...

(Submitter supplied) In our study, we investigated for contractile activity-specific changes in the transcriptome in untrained and trained (after an aerobic training programme) human skeletal muscle. The second goal was to examine effect of aerobic training on gene expression in muscle at baseline (after long term training). Seven untrained males performed the one-legged knee extension exercise (for 60 min) with the same relative intensity before and after a 2 month aerobic training programme (1 h/day, 5/week). more...
