Project description:vastus lateralis biopsies were obtained from healthy subjects, either young adults (20-29 yr old) or older (65-75 yr old) Keywords = muscle Keywords = aging Keywords: other
Project description:This series includes the global gene expression profile of the vastus lateralis muscle for 10 young (19-25 years old) and 12 older (70-80 years old) male subjects. Keywords: other
Project description:Aging is associated with mitochondrial dysfunction and insulin resistance. We conducted a study to determine the role of long-term vigorous endurance exercise on age-related changes in insulin sensitivity and various indices of mitochondrial functions. Keywords: The effect of excises in young and old human subjects by transcription profiling
Project description:Gene expression approach to differences in stress response between human skin fibroblasts derived from chronologically young (~20 years) and old (~90 years) subjects. Expression of CDKN2A was most different between fibroblasts from young and old subjects and
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:Genome wide DNA methylation profiling of muscle cells extracted from healthy donors at different ages. The Illumina Infinium Human Methylation 450 BeadChip was used to obtain DNA methylation profiles across > 485,000 methylation sites. The muscle cells were extracted from young adults (18-40 years old) and elderly (>70 years old)(n=3 per group, 2 groups : Young and aged adult).
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. A total of 36 subjects were included in this investigation. The young (n=15, 25±1y) participants included 7 males and 8 females. The old (n=21, 78±1y) participants included 10 males and 11 females. All subjects were healthy and had never been involved in any formal exercise. Skeletal muscle biopsies were obtained from the vastus lateralis in the basal state. The RNA integrity of all 36 samples was very good with an average RIN number of 8.2. All samples were analyzed on a separate microarray chip, and samples were not pooled between subjects.
