Project description:To define the skeletal muscle adaptations induced by exercise performed at high altitude hypoxia, we investigated if the gene expression profile of Vastus lateralis muscle was affected by 5000 m-above-sl-expedition. Two-condition experiment, Vastus lateralis muscle biopsy post-expedition vs Vastus lateralis muscle biopsy pre-expedition. Five volunteers/climbers. Biological replicates: 1 pre-expedition sample, 1 post-expedition sample.

Project description:Recreationally-trained college aged males underwent 10 weeks of moderate volume, high-load resistance exercise with PRE and POST vastus lateralis skeletal muscle biopsies. Protein isolation was performed on tissue samples and the sarcoplasmic protein fraction was analyzed to evaluate changes PRE to POST.

Project description:The goal of these studies was to determine the effects of fasting on skeletal muscle mRNA levels in healthy human subjects. Seven healthy adult human subjects fasted for 40 hours and then a muscle biopsy (fasting sample) was obtained from the vastus lateralis muscle. Immediately after the first muscle biospy, subjects then ate a mixed meal. Six hours after the first muscle biopsy, a second muscle biopsy (fed sample) was obtained from the contralateral vastus lateralis muscle. In each subject, mRNA levels under fasting conditions were normalized to mRNA levels under fed conditions, which were set at 1.

Project description:We assessed vastus lateralis muscle gene expression levels of 12 women with the metabolic syndrome before and after a 6 month exercise training program RNA was isolated from a vastus lateralis muscle biopsy of 6 women with the metabolic syndrome before and after a 6 month guided endurance exercise training program

Project description:Global microarray (HG U133 Plus 2.0) was used for the first time to investigate the effects of resistance exercise on the transcriptome in slow-twitch myosin heavy chain (MHC) I and fast-twitch MHC IIa muscle fibers of young and old women. 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. A total of 14 females were included in this investigation. The participants included 8 young (23±2y) and 6 old (85±1y) females. All subjects participated in 12 wks of progressive resistance training consisting of bilateral knee extensions with 3x10 reps at 70% of 1-RM, and 3d/wk for a total of 36 training sessions. Vastus lateralis biopsies were obtained in conjunction with the 1st and 36th (last) training session and included a basal biopsy and another biopsy 4hrs post the resistance exercise session. From each biopsy sample, we isolated individual muscle fibers. After myosin isoform identification of isolated fibers (SDS-PAGE), RNA extraction of 20 MHC I and 20 MHC IIa muscle fibers per biopsy sample followed. Thus, each resulting sample contained total RNA from 20 muscle fibers of identical fiber type (MHC I or MHC IIa). A total of 70 samples were analyzed on separate microarray chips, and samples were not pooled between subjects. The study design allowed us to examine the acute effects of resistance exercise on the transcriptome in MHC I and MHC IIa muscle fibers in the untrained and trained state.

Project description:Fasting muscle biopsy samples from the vastus lateralis were collected from lean (LN: BMI < 25 kg/m2) and obese (OB: BMI > 40 kg/m2) subjects. Primary myoblasts were isolated from the biopsy samples, maintained in vitro, and differentiated to myotubes.

Project description:Global microarray (HG U133 Plus 2.0) was used to investigate the basal level skeletal muscle transcriptome profile of young and old adults. One vastus lateralis muscle biopsy was obtained in the basal state from 36 different subjects.

Project description:Transcriptome wide analysis of the skeletal muscle response to exercise in humans. Subjects performed one 60-min bout of moderate-intensity single-leg knee-extension exercise, and samples were obtained by biopsy of the vastus lateralis muscle before, immediately after, and at 3 hr post-exercise. Eight subjects were control (no drug), and eight received combined H1/H2-histamine receptor blockade prior to exercise.
